Before a health plan pays for an expensive specialty drug, it wants proof that the patient meets its written conditions. Prior authorization support is the office work that supplies that proof: reading what the plan demands, finding the page in the patient's chart, filling in the plan's form and getting a letter signed by the doctor. One line without proof can bring a denial weeks later, while the patient waits to start treatment.
This guide is for anyone who does this work or pays for it: prior authorization (PA) coordinators, prescribers and practice managers in specialty offices, and the patient services and field reimbursement teams at drug makers who support those offices. No background needed.
Imagine you are the prior authorization coordinator at a dermatology and rheumatology practice. Dr. Maya Chen wants Jordan Reyes, 41, who has had plaque psoriasis since 2019, to start Veltrimab, a biologic (a drug made from human, animal or microbial sources). She wrote the prescription at 4:20 pm on October 6, 2026, and by the next morning, a Wednesday, the plan's approval is your job. His plan, Crestline Health, has a policy with six lines. The chart export, the set of pages the office pulled from his record, runs to 46 pages.
You go line by line. Five are fine. Line 4 asks for at least three months of methotrexate, an older drug, documented in a visit note.

Jordan did take methotrexate, for 18 weeks. Dr. Chen saw him twice by telehealth, on January 6 and May 12, and a retail pharmacy filled it five times. None of that came out with the chart. Sent as it stood, this request would have looked as if he had skipped a required step.
Good prior authorization support catches that line on the first day, finds the missing pages, and leaves the decision and the signature to the doctor.
Proving a specialty drug request: the plan's criteria, the legal clocks, the chart evidence, the letter and the people who carry it
What the office has to prove, which rules set the plan's deadline, how requests fail and who does the work, explained without selling anything. If you have never seen a prior authorization, start here.
01 · In plain words
What prior authorization support means for one patient and one prescription
The prescription is written and the pharmacy has it, yet the expensive medicine stays on the shelf. The patient's health plan wants to see proof first, and until it has that proof it will not pay. This advance approval is called prior authorization, or PA. Without it, most patients cannot afford to start.
The plan keeps a written list of what it wants for that medicine: the diagnosis, how severe the disease is, what kind of doctor is prescribing, which older drugs the patient has already tried, and a few screening tests. Someone in the doctor's office has to read that list, open the patient's chart and find the page that answers each line. That person is often called a PA coordinator, and on a busy day the requests stack up across several doctors.
When the proof is together, the coordinator fills in the plan's form, or answers its questions on an electronic system. For a specialty drug the office often adds a letter of medical necessity: a short letter, signed by the prescriber, that explains why this patient needs this treatment. Then the request goes to the plan, and the waiting starts.
Prior authorization support is the name for all of that preparation and follow-up. Drug makers' patient services programs use the phrase for the help they offer offices, and specialty practices use it for the job itself. It sits on the office side of the table. The plan's own review, which ends in a yes or a no, is a separate job done by different people under different rules.
One specialty drug request in five steps, and the step where the proof gets built
The prescriptionThe doctor chooses a therapy. The office learns the plan wants prior authorization before it will pay.
The plan's listThe coordinator finds the plan's current policy for this drug and this disease, with its form or electronic questions.
The proof, line by lineEach line is matched to a chart page, gaps are chased, the form is filled and the letter is drafted. This is the step this guide is about.
The signature and the sendThe prescriber reviews the request, signs it and it goes to the plan, by electronic request, portal, fax or phone.
The decisionThe plan approves, asks a question or denies. A denial starts an appeal, and the patient keeps waiting.
What new PA coordinators find surprising about the work
The proof is often already in the building
A telehealth visit, an outside lab or a fill at a retail pharmacy may never reach the chart export, the set of pages pulled from the record, that a coordinator works from. The patient did the step. The packet does not show it.
The famous federal deadline skips drugs
The 7-day and 72-hour rule that took effect on January 1, 2026 "does not apply to prior authorization decisions for drugs".1 Drug requests run on other clocks, some of them shorter.
A denial letter may leave out who decided
In one published review of dermatology denial letters, 75% did not identify a decision maker and 41% gave no information on step therapy or covered alternatives.2
Few denials are appealed, and most appeals win
In Medicare Advantage, the private plans within Medicare, 11.5% of denials in 2024 were appealed and 80.7% of those appeals were overturned at least in part.3 Those figures come from Part C (Medicare Advantage) data, which KFF, a health policy research group, does not break out by service.
What PA, step therapy, an LMN and ePA mean
Prior authorization (PA)
A plan's advance approval for a treatment, given only if the patient meets written conditions.
Step therapy
A plan's rule that a patient must try a preferred or older drug first, and have it fail or cause trouble, before it pays for the prescribed one.
Letter of medical necessity (LMN)
A letter signed by the prescriber explaining why this patient needs this treatment, usually sent with the request or an appeal.
ePA
Electronic prior authorization: the request and the plan's questions travel as structured data from the office's system to the plan's, in place of fax and phone.
What the prescriber's office prepares, what the plan decides, and where a drug maker's program may help
In shortThree parties touch a specialty request. The office owns the request and the prescriber signs it. The plan or its pharmacy benefit manager (PBM) reviews and decides. A manufacturer's support program may help offices understand the process, under limits explained in section 12.
People search for "prior authorization automation" and find two different markets. One serves plans, whose reviewers decide requests. The other serves offices, whose staff prepare them. A tool for one is close to useless for the other, because the two jobs start from opposite documents. A reviewer starts with a request and asks whether it meets the policy. A coordinator starts with a chart and asks what in it proves each line, and what is missing.

A specialty policy is short to read and slow to satisfy. The fictional Crestline policy in this guide has six lines, and two of them are step therapy. Those two lines are where the evidence is hardest to collect, because they reach back across months of care, several drugs and sometimes several pharmacies.

Coverage can also sit in two places. A self-injected drug usually falls under the pharmacy benefit, reviewed by a PBM. A drug given in a clinic usually falls under the medical benefit, reviewed by the plan's medical team. A coordinator has to know which applies before choosing the form. The Centers for Medicare & Medicaid Services (CMS), the federal agency that runs Medicare, treats the two differently in its drug proposal, as section 05 explains.4
03 · CMS-0057-F, dated
CMS-0057-F, the prior authorization rule: what began January 1, 2026, what comes January 1, 2027, and why drugs sit outside it
In shortCMS's Interoperability and Prior Authorization final rule was released January 17, 2024. Decision deadlines and specific denial reasons began January 1, 2026, the first public metrics were due March 31, 2026, and the data links known as APIs generally follow by January 1, 2027. Every part of it excludes drugs.
CMS-0057-F's dates run from a 2024 release to APIs in 2027, and none of them covers a drug
Jan 17, 2024Final rule released
CMS publishes its fact sheet on CMS-0057-F.

Jan 1, 2027APIs due
Patient Access, Provider Access, Payer-to-Payer and Prior Authorization. Exact dates vary by payer type.
Calendar 2027Electronic PA measure moves
CMS-0057-F set 2027 for hospitals and for clinicians in MIPS, Medicare's clinician quality program. The FY 2027 inpatient rule made it an optional bonus for hospitals in 2027, required from 2028. CMS has proposed the same shift for clinicians.
Which plans CMS-0057-F reaches, and the exchange plan exception
The rule names its "impacted payers": Medicare Advantage organizations, state Medicaid and Children's Health Insurance Program (CHIP) fee-for-service programs, Medicaid managed care plans, CHIP managed care entities, and qualified health plan issuers on the federally facilitated exchanges, the federally run marketplaces for health coverage.1
Those exchange plans are excluded from the decision deadlines, a detail many summaries drop.1 Employer plans and most other commercial coverage are outside the rule altogether: they answer to ERISA, the federal law on employer benefit plans, the Affordable Care Act's claims rule and state law, as section 04 sets out.
How the deadline works when it does apply
Standard requests: seven calendar days. Expedited requests, the fast-track kind: 72 hours. CMS measures both in "calendar time, not business hours".8
The clock starts when the payer receives the request, and it "does not stop or restart" if the payer later asks for documentation it had not disclosed to the provider.8 Some programs may grant an extension of up to 14 calendar days.8
A denial must carry a specific reason, whichever way the request was sent.1
Metrics go on each payer's website every year, starting with 2025 data by March 31, 2026.8
The sentence to remember. CMS's fact sheet says: "As with all policies in this final rule, this provision does not apply to prior authorization decisions for drugs."1 CMS's questions page repeats it: the deadlines cover medical items and services, "excluding drugs".8 So a psoriasis biologic is outside CMS-0057-F whichever plan the patient has. A vendor or a colleague who says "CMS now requires a seven-day answer on drug PAs" is mistaken.
Why a specialty office should still follow this rule
Three things reach the office anyway.
The systems. The Prior Authorization API and the CMS measure that asks clinicians and hospitals to request PA electronically put these requests onto the health record systems offices use. They start with non-drug care, and CMS has proposed extending them to drugs.4,7
The metrics. They give the office a first public view of how each large insurer behaves, and KFF's first analysis of them appears in section 10.
The denial reason. The habit of a specific reason sets an expectation an office can use when it asks a commercial plan or a PBM to explain itself.
04 · Clocks for drug requests
How long a plan has to answer a drug prior authorization: 24 hours in Medicaid, 72 in Part D, up to 15 days in an employer plan
In shortDrugs left out of CMS-0057-F still have deadlines, set by the rule for each type of coverage. Medicaid and expedited Part D requests run on 24 hours. Standard Part D runs on 72. An ERISA employer plan may take 15 days on a pre-service request. Knowing which clock applies tells the office when to chase.
The legal deadline on a drug request runs from 24 hours to 15 days, depending on the coverage

45 CFR 147.136; state law
Part D's rule also sets what the prescriber must say to win an exception to a step. The statement has to say the drug is medically necessary, and give a ground: the required alternatives have not worked, are likely not to work for this patient, or are likely to cause harm.18 The plan may ask for that in writing and may ask for documents.18 A coordinator who knows this drafts for the prescriber the facts that support one of those grounds, then lets the prescriber decide whether it is true.
A deadline measures only the plan's part of the wait. It starts when a request arrives. The days spent finding pages, chasing notes and waiting for a signature come before that, and no rule counts them. Section 11 shows the published waits.
05 · Drug ePA and CMS-0062-P
Electronic prior authorization for drugs: CMS-0062-P is still a proposal, and the NCPDP dates that are already set
In shortCMS proposed in April 2026 to bring drugs into electronic prior authorization, with most changes from October 1, 2027. As of November 2026 it has not been finalized. Part D already has its own electronic standard, with a firm date of January 1, 2028. ePA moves the questions faster. It does not find the proof.
What the drug proposal would do, if finalized
Status: CMS-0062-P was published at 91 FR 19890 on April 14, 2026, and the comment period "closed on June 15, 2026".4,19 CMS's page still called it proposed on November 3, 2026, and we found no final rule.19 One part has moved: the FY 2027 inpatient payment final rule adopted updated electronic PA data standards first listed in the proposal, effective October 1, 2026, according to WEDI.20
Who: Medicare Advantage, Medicaid and CHIP programs and plans, exchange plans, and small-group exchange issuers.4,17
How: drugs under a medical benefit through the FHIR Prior Authorization API; drugs under a pharmacy benefit through NCPDP standards. FHIR and NCPDP are data formats that let systems exchange requests.4
When: October 1, 2027 for most changes, with drug metrics starting in 2028.4,17
Part D: covered Part D drugs stay under their existing rules. Plans that offer both Medicare Advantage and Part D would report drug metrics only for Part B drugs.4,17

What ePA changes in the office, and what it leaves alone
An electronic request sends the plan's questions into the prescriber's system and the answers back. It removes faxes, retyping and hold music. CAQH's yearly index covers medical and dental transactions, and reports electronic adoption of medical PA rising from 31% in its 2023 edition to 40% in its 2025 edition. We read a trade report of the index, which gives no figure for drug requests.23
The same index puts potential medical savings from automating remaining manual transactions at $18.7 billion a year, across all medical transaction types.23 We found no public figure for the share of specialty drug requests sent electronically.
Electronic medical PA reached 40% in the 2025 CAQH Index, up from 31% in the 2023 Index
Speed depends on what the electronic question finds. One network vendor reports approvals "returned in just 18-seconds" on 83 medications, with 45,275 prescribers enabled across 20 health systems in 2025. That is a company's own claim, and the release gives no method.24 A result like that needs the answers to be ready. An electronic question that asks "documented trial of methotrexate, at least 3 months?" still needs someone to know whether the answer is yes and which page shows it.
The insurers' 2025 pledge: fewer requests so far, and no figures for drugs
In June 2025, health insurers made a voluntary pledge to reduce and simplify prior authorization. By April 2026 they reported about 11% fewer requests, roughly 6.5 million, and over 15% fewer in Medicare Advantage.25
AHIP, the health insurers' trade group, describes a 2027 commitment that at least 80% of approvals on electronic requests with all necessary documents will come in real time.26 The reports we read do not show these figures reaching prescription drugs, so an office should not plan on them for a biologic. Physicians are cautious too: in the American Medical Association's December 2025 survey, 33% believed the pledge would make a meaningful difference.26
06 · Reading a plan's criteria
Payer medical-necessity criteria for biologics: step therapy, specialist rules and limits that have grown stricter than the label
In shortA plan's policy is a list of conditions, and its small words decide requests: AND, OR, "at least", "documented in", "within". Commercial specialty policies have tightened: by 2021, 51.7% were stricter than the drug's FDA-approved label, and step therapy and prescriber rules had both grown. Step therapy laws help in some states and do not reach most employer plans.
The six kinds of line in a specialty policy, read from the fictional Crestline one
Kind of line
Example from the fictional Crestline policy
The word to watch
Diagnosis
Member is 18 or older with moderate to severe chronic plaque psoriasis documented for at least 6 months.
"Documented": a diagnosis since 2019 needs a page that says so.
Severity
At least one of: body surface area (BSA) 10% or more; PASI, a standard psoriasis score, 10 or more; plaques on hands, feet, scalp, face or genitals.
"At least one of": one proven option is enough. Name which.
Prescriber and dose
Prescribed by, or in consultation with, a dermatologist; dose within the label.
"In consultation": a referring note may count.
Older therapy
Inadequate response or intolerance to at least 3 months of methotrexate, or cyclosporine or acitretin when methotrexate is contraindicated, after topical therapy.
"Or", "when", "after": three conditions in one sentence.
Preferred drug
Inadequate response, intolerance or contraindication to the preferred biologic after at least 12 weeks.
"12 weeks": a count that fills can confirm.
Screening
Negative screening for latent tuberculosis within 12 months before the first dose; no active infection; not used with another biologic.
"Within": an old result is as bad as no result.
How specialty coverage has tightened since 2017
More than half of specialty policies were stricter than the label by 2021, and prescriber rules had doubled
Share of coverage policies at large US commercial plans
Those figures come from a Tufts analysis of 4,418 policies in 2017 and 4,998 in 2021, across 357 drug and indication pairs.27 They are shares of policies and stop at 2021, the latest published year.
An earlier study found step therapy on 38.9% of specialty coverage policies, ranging from 20.6% at one plan to 57.5% at another.28 Medicare has moved the same way: Part D plans restricted an average of 31.9% of compounds in 2011 and 44.4% in 2020, counting prior authorization, step therapy and exclusions from the plan's covered drug list, on non-protected-class compounds.29
What step therapy laws do and do not reach
A 2026 article in the American Bar Association's Health eSource counts 38 states plus D.C. with some form of step therapy regulation.30 What those laws do for a patient depends on who stands behind the plan.
Kind of plan
What state step therapy law can do
What an appeal can lean on
A plan the state can regulate
Require an exception process and set response times.30
The state's exception process, as well as the plan's own criteria.
A self-funded employer plan
Little: a state cannot generally regulate these plans.30
The plan's own criteria and any exception route it offers.
The federal Safe Step Act (S. 2903), introduced September 18, 2025, would close that gap, and we found no record of its passage as of November 2026.31 So the same step may be contestable for one patient and untouchable for the next, in the same waiting room. An office needs to record which kind of plan each patient has, because the appeal letter changes with it.
Plans also rewrite these lists. When a new version arrives, a request that was fine last week may fail today. A separate guide on this site, payer coverage policy tracking, covers that work from a drug maker's seat. An office's version of the problem is smaller: know which version applies to this request, and use only that.
07 · Finding and counting the proof
Where the proof for a PA criterion hides, and how to count weeks on therapy, lab age and either-or lines
In shortChart exports leave things out: telehealth notes, outside labs and fills at another pharmacy. Most errors in this work are small sums done by hand: weeks from fill dates, days since a lab, which option of an either-or line applies. Working these through with one fictional patient shows why a person should see the page behind each number.

Did Jordan stay on the preferred biologic for 12 weeks?
First dose June 2, last dose September 15, 2026: 105 days, or 15 weeks. Four 28-day fills dispensed 16 weeks of supply, which agrees.
Met. Fifteen weeks taken, 12 required.
Did he take methotrexate for 3 months?
January 6 to May 12, 2026: 126 days, or 18 weeks. Five 28-day retail fills, the last on April 29, cover the period to May 27.
Met once the telehealth notes and retail fills are attached. Without them, unmet.
Is the TB test recent enough?
The chart holds two. The result from August 4, 2025 is 14 months old on October 7, 2026, outside the plan's 12 months. The result from October 3, 2026 is 4 days old.
Met on the newer test. A hurried reader who finds the older page first could reach the wrong answer.
Theo Lindqvist's liver tests: within 90 days?
Last panel April 28, 2026. On October 7 that is 162 days. Silverpine's policy allows 90.
Unmet. The cure is a new blood test, ordered by the doctor.

When visit notes and pharmacy fills disagree, the prescriber sees both
Notes can be vague, and fills can overstate. A fill proves only that a pharmacy handed over a box. The patient may have missed doses, and a fill after a drug was stopped says nothing about treatment. A note can round "about three months" up. Offices that compare the two see disagreements early. The right response is to show the prescriber both pages and let the prescriber say what happened, even when one version would meet the policy and the other would not.
Wording matters as much as dates. "Failed methotrexate" in a template is weaker evidence than "inadequate response at 18 weeks, BSA 15%". If the note says less than the policy asks, the fix is a new or amended note written by the clinician who knows. A stronger word in the letter fixes nothing.
HIPAA, the federal health privacy law, also matters here. Its minimum necessary standard applies to what you send a plan: reasonable efforts to limit information to what the purpose needs.32 It is good practice as well, because a reviewer reading 17 pages with passages marked finds the proof faster than one reading 51.
08 · The letter of medical necessity
What a good letter of medical necessity contains, why every sentence must trace to the chart, and who has to sign it
In shortA letter of medical necessity explains, in the prescriber's voice, why this patient needs this treatment. It works when each statement points to a chart page and the prescriber has read it. Templates fail in two ways: they say nothing specific, or they claim more than the chart holds. A clinician signs, always.

"Methotrexate 15 mg weekly for 18 weeks, January 6 to May 12, 2026, stopped for inadequate response and a rise in ALT, a liver enzyme, to 2.4 times the upper limit."
The plan's line asks for a drug and a length. Only the second sentence answers it.
"Disease is severe and debilitating."
"BSA 14% including scalp and both palms; DLQI 17."
The plan set thresholds. Give the numbers it asked for. DLQI is a patient questionnaire on how a skin disease affects quality of life.
"The drug is the only appropriate option."
Only what the prescriber judges and can defend.
A claim beyond the chart costs credibility with reviewers and exposes the person who signs.
Why the prescriber's name on a request has real weight
A prior authorization request is a statement to a payer on behalf of a named clinician. In November 2021 the US Department of Justice announced a $12.7 million False Claims Act settlement with a drug maker, kaléo. The government alleged that pharmacies submitted false prior authorization requests for its product, misrepresenting that prescribers had submitted them, between March 14, 2017 and April 30, 2020.33 The release states that these are allegations only, with no determination of liability.33
For any office, the lesson is that the person whose name is on the request reviews it, the login belongs to that person, and nobody else submits as them.
Coordinators may draft. Software may draft. A clinician reads what was drafted, changes what is wrong and decides whether to sign. Anything clinical in a request, including a claim about why a treatment failed, is that clinician's statement.
09 · How requests fail
Missing notes, stale labs, old forms: eight failures a specialty PA request carries to the plan
In shortMost failures are preventable in the office: a missing note, a lab out of date, a form from last year, a letter that says too little. No public study counts these eight causes across practices, so the ranking below is our judgment. Your own denial letters will rank them for you.
What goes wrong
Why it happens
How to catch it
1. Evidence outside the export
Telehealth, outside labs and other pharmacies sit in separate systems.
When a line looks unmet, search those sources before sending.
2. A step too short
Weeks counted to a check-in visit, short of the trial's end.
Count from first dose to last dose, and compare with fills.
3. A lab out of its window
The chart holds a result, so no one checks its date.
Date every lab against the plan's window, and order a new one early.
4. An old policy version
Coordinators rely on memory or a saved PDF.
One approved version for each plan and drug, changed by a named person.
5. The wrong form or benefit
Pharmacy and medical benefit routes differ.
Confirm the benefit before you start the form.
6. A severity score never recorded
The visit note describes the disease and gives no score.
Ask the prescriber to record it at the next visit or in an addendum.
7. A template letter
Time pressure, and a letter that "usually works".
Check each statement against a page.
8. A plan's question left unanswered
A fax or portal message nobody watches.
One owner, and a date on every open request.
Missing evidence and short steps are worth fixing first: common, and costly when they reach the plan

Two small studies show how much of this comes back. At one complex dermatology clinic, 51% of 51 prior authorizations were first denied, with systemic drugs denied more than topical ones.34 At one rheumatology center, 21% of infused-drug requests were first denied, and 82% of those were eventually approved.35 Neither is a national rate, and the second suggests something a coordinator knows well: many first denials end in approval, after a delay the patient should not have had.
10 · Denials and appeals
What PA denial letters leave out, what the first public metrics show, and how often an appeal wins
In shortDenial letters often do not say who decided or what would have worked. Published data show low appeal rates and high success rates, but the Medicare Advantage figures do not separate drugs and the newer metrics leave drugs out. For a drug request, your own denial and appeal log is the best evidence you will get.
Three in four dermatology denial letters did not identify a decision maker
75 in 100
denial letters named no decision maker. Only 7% gave the reviewer's full name
denial letters named no decision maker. Only 7% gave the reviewer's full name
75 of 100
That review, published in the Journal of the American Academy of Dermatology, also found that 41% of letters gave no information on step therapy or covered alternatives, and that among appeal denials only 31% engaged with the prescriber's arguments.36,2 We read a report of the paper and not its full text, and that report does not give the number of letters. A denial that names no missing fact is hard to answer.
The Medicare Advantage funnel from request to overturned denial
Of 4.1 million Medicare Advantage denials in 2024, about 470,000 were appealed and about 380,000 overturned
Part C determinations, millions. Appealed and overturned counts are our arithmetic from KFF's percentages
KFF's data are Part C organization determinations, the plans' coverage decisions, and CMS does not report them by service type, so they do not tell you about drugs under Part D or a specialty biologic under an employer plan.3 A high overturn rate also does not prove the first denial was wrong. It may mean only appeals with good evidence were filed, or that the missing page finally arrived. Denial rates ranged from 4.2% to 12.8% among large insurers.3
What the first CMS-0057-F metrics reveal, and where they stop
Marketplace plans denied the most non-drug requests in 2025, and expedited requests were denied a little less often
Denial rate by market, 14 insurers, calendar 2025, drugs excluded
KFF's analysis, published August 13, 2026, read the metrics of 14 insurers. Median response was about one day on standard requests, and on expedited requests about 0.4 days in Medicare Advantage, 0.8 in Medicaid managed care and 1 day in the Marketplace.37 On standard requests, appeals overturned denials 67% of the time in Medicare Advantage, 47% in Medicaid managed care and 43% in the Marketplace.37
KFF lists the gaps: percentages with no counts, no service categories, optional templates, no share of decisions beyond the deadline, and nothing on self-funded employer plans. It also confirms that drugs are not in these metrics.37
Five moves that answer a drug denial: reason, deadline, pages, call, log
Read the stated reason against the chart. If the plan says "a trial of 8 weeks", find out which page it read.
Check the deadline. ERISA plans must give at least 180 days to appeal.13 Part D denials must describe the standard and expedited redetermination processes; redetermination is Part D's first level of appeal.9
Answer that reason and nothing else first. Quote the note, cite the fills, and attach only those pages.
Offer the prescriber a peer-to-peer call, a conversation with the plan's clinician, if the plan allows one. The prescriber decides whether to take it.
Log the outcome by plan, drug and reason. Over a year that log tells you where requests fail.
11 · Waits and workload
How long patients wait for a biologic, and the hours prior authorization takes from a practice
In shortPublished waits for a biologic run from about a week to well over a month, depending on the plan and the setting. Physicians report 40 prior authorizations a week and 13 hours of work. A US count of specialty drug requests does not exist in public data. Measure your own.
40
prior authorizations per physician per week, in the American Medical Association's survey of 1,000 physicians in December 2025.38
Physicians' own reports, all kinds of PA
13 hours
of physician and staff time a week on those requests, in the same survey.38
About 20 minutes a request, by our division
79%
of those physicians say PA "sometimes, often, or always" leads patients to abandon treatment. 95% report care delays.38
What physicians report
Published waits for specialty drugs, by plan and by denial
Patients with private plans waited about five times longer for a biologic than those on Medicare
Mean days to biologic approval, one Miami health system, 101 patients
Those patients, with psoriasis or psoriatic arthritis, came from one academic health system, and the need for prior authorization significantly predicted a longer wait.39 Same-day approval went to 63% of Medicare patients and 11.5% of those in PPOs.39 The records run from 2000 to 2019, so today's numbers may differ.40 It remains one of few published views of biologic waits for this disease.
A denied request added about three weeks to the wait for an infused drug in rheumatology
Median days from request to infusion, one center, 225 patients. "PA required" includes the requests first denied
That study also found higher steroid exposure in the three months after a denial: a median of 605 mg against 160 mg of prednisone equivalent when no authorization was needed.35 A delay here keeps patients on older treatment while they wait. It is a single-center study, and it cannot prove the denial caused the difference.
Nearly half of dermatology PA decisions took more than a week, by providers' own account
Respondents' estimate of how long determinations take, February 2020 survey. The survey gives the 45% beyond a week and the 17%; the other two bands are our subtraction
The American Academy of Dermatology's survey found that dermatologists and staff spent a mean of 3.3 hours a day on PAs, 60% of dermatologists interrupted patient visits for them, and 12% of PAs led to delaying or abandoning treatment.41 A separate tracking study gave a median of 30 minutes a request, with a middle range of 17 to 105 minutes, and a median 12-day delay to treatment.34 That range is wide because easy renewals and hard biologic starts are different jobs.
The size of the work, and what no one publishes
Medicare Advantage insurers made 52.8 million determinations in 2024, about 1.7 per enrollee.3 We found no public figure for US drug prior authorizations, for the cost of one, or for coordinator hours by step. Any number you see for those in a sales deck is an estimate, and you should ask where it came from. You can measure all of them in your own office within a week, as section 18 shows.
12 · Support from a drug maker
What a manufacturer's patient services team may do on a prior authorization, and what stays with the practice
In shortA drug maker's patient support service, called a hub, and its field reimbursement team often offer prior authorization support. The conservative line is clear: the practice owns the request and the prescriber signs it. The program sees what the patient has agreed to share, and any help must carry no reward for prescribing. Get counsel to review the design.
Drug makers run patient support programs, with hub case managers and field reimbursement managers who help offices understand a plan's process. Patient enrollment and benefit checks are separate pieces of work, covered in their own guides. This section is about one question: how far that help may reach into the request itself.
Anti-kickback, HIPAA and false statements: the rules that limit a program's help
Anti-kickback. The federal health department's Office of Inspector General (OIG) issues guidance on the law against paying for referrals. Its 2003 guidance for drug makers says of reimbursement consultation and similar product support: "Standing alone, services that have no substantial independent value to the purchaser may not implicate the anti-kickback statute." It warns about offering them in tandem with another service that benefits a referring provider, such as a reimbursement guarantee.42 OIG's site lists the 2003 text as archived and shows no publication date for a replacement.43 Take this to counsel, because the analysis depends on the facts.
HIPAA. Sharing a patient's information with a manufacturer's program generally needs a valid authorization, which names the information, who shares it, who receives it, the purpose and an expiry, and carries the patient's signature.44
False statements. The kaléo settlement described in section 08 is a warning about anyone other than the prescriber submitting in a prescriber's name.33
A conservative design keeps chart pages, letters and signatures inside the practice
A design to review with counsel; no law prescribes it. Program access assumes the patient's signed authorization

A program that keeps to status and general education avoids most of these questions. It can tell an office the status of a case the patient has agreed to share, explain publicly what kinds of evidence plans commonly ask for, and leave the rest to the office. If a program wants to do more, such as pay for software an office uses, that is a question for counsel before anyone signs anything, because a free tool can have independent value.42
13 · AI on the office side
Where AI fits between a chart and a PA policy, which rules reach it, and what a clinician keeps
In shortSoftware can read charts, match lines to passages and draft letters, and early studies are promising under tidy conditions. The hard part is the mess: incomplete records and administrative details. Most AI guidance for drug makers does not reach this office work, while HIPAA does. A clinician signs anything clinical.
What the early evidence on AI-drafted PA letters says
The most direct study we found is a preprint dated March 31, 2026, which has had no peer review. Two independent researchers ran three commercial language models across 45 physician-validated, synthetic scenarios in five specialties, 135 letters in all.
Their checks of all 135 letters, with five read line by line, detected no invented clinical facts, and the models averaged above 97% on the authors' rubric. They also found gaps that clinical scoring missed: absent billing codes, missing requests for an approval period and weak follow-up plans.45 The authors warn that all the facts were handed to the models in the prompt, and that the risk is likely higher with incomplete real records.45
Read that as an argument about how such a tool should be built. The drafting step works when the facts are already extracted and tied to pages. Most of the value and risk then lie in the steps before and after it: reading messy records accurately, saying when something is missing, and having a person check.
Start with the long steps a person can check quickly; judging clinical need stays with the prescriber

A state example of rules on automated decisions. Its main sections do not apply to a HIPAA covered entity, or its business associates for services to it, except on employment decisions. A provider must operate from Colorado for that, and owes patients a general notice of such tools.52 Other states differ, so check yours with counsel.
Five ways AI drafting can go wrong on a real PA chart
Records it never saw. Software can only cite what it was given. "No evidence found" must list where it looked.
Poor scans and handwriting. Faxes from outside labs misread easily. A reader should show the page beside the value.
Upgraded wording. A drafter may turn "some improvement" into "inadequate response". Quoting the note protects against this.
Policy changes. Criteria change. A tool must say which version it used, and a person must approve a new one.
Administrative detail. As the preprint found, codes, approval periods and form fields need their own checks.45
14 · Who does the work today
Who runs prior authorization in a specialty practice: coordinators, prescribers, managers and the pharmacy behind them
In shortA coordinator carries most specialty requests from a chart export, a saved PDF and a phone. The prescriber signs between patients. Help may come from a specialty pharmacy, a central team or a manufacturer's program. Time goes to chasing evidence and following up. No public study breaks this down by step, so measure it in your office.
Six roles a biologic request passes through in a practice
PA
PA coordinator
Reads the policy, works through the chart, fills the form, chases gaps and watches the plan's clock.
Cares about: which line will get this request denied.
RX
Prescriber
Decides on the therapy, owns the clinical statements, signs requests, letters and appeals.
Cares about: everything above their name being true.
MA
Medical assistant or nurse
Pulls records, orders repeat labs at the doctor's request, calls patients about missing fills.
Cares about: a clear list of what is missing.
PM
Practice manager
Owns staffing, turnaround and the rules the office applies on top of each plan's.
Cares about: where the days go, and who can cover a vacation.
SP
Specialty pharmacy liaison
Holds the fill record, and in some models starts or completes parts of the paperwork.
Cares about: a request ready before the fill.
PS
Support program contact
A hub case manager or field reimbursement manager, seeing status with the patient's consent.
Cares about: knowing a case's status without touching the chart.

How it works
Where it strains
In-house coordinators
One or more staff work every request, using portals and fax. Common in independent specialty practices.
Knowledge sits in one person's head, and absence stops the queue.
A central or pharmacy-led team
A health system's pharmacists or specialty pharmacy liaisons handle requests across clinics. Some conference posters report better approval rates, in small designs, often from pharmacy vendors.53
Distance from the prescriber, and evidence in clinic systems they cannot see.
Software on top of either
Electronic request tools move the questions. Newer tools read the chart and draft answers, for staff to check.
Evidence outside the connected record, and trust until measured on your own files.

One psoriasis request in Botminds Prior Authorization Support: a 46-page chart, a missing step and a signed approval

15 · One request, start to finish
One unmet line on day one, 18 weeks of methotrexate recovered, and Jordan Reyes's request signed the next morning
In shortPriya Ranvelle, the practice's PA coordinator, opens Jordan's request against Crestline Health's six-line policy. Five lines come back met and one unmet. A search of the practice's own record finds the missing proof. Six agents do the reading and drafting, and Dr. Maya Chen reviews and signs. In the sample, the plan approves 0.7 days after the prescription.

Crestline's six criteria sit beside an empty column
Jordan's chart arrived at 7:52 am: 46 pages in 8 documents. Priya opens his request against Crestline's policy CHP-RX-118, version 2026.10, Commercial. Each criterion shows in the plan's own words, with its verdict and evidence still empty. Across the top are the morning's other requests, each with its count and state, so she can see what else needs her.
On the right the ready-to-submit pack waits, with five empty parts: proven criteria, payer form, letter, cited pages and the prescriber's signature. It reads "nothing goes to the payer before it".
Before the match. The payer's criteria in its own words, and every verdict still waiting. The biologics' doses are taken off these sample screens; the case does not depend on them.
2
Three agents read the chart in view
Priya presses "Match the chart". The Chart Reader reads 46 pages and 8 documents in 38 seconds in the sample, every fact with its page. The Therapy History Builder finds 3 prior therapies and checks their dates against pharmacy fills in 6 seconds. The Criteria Matcher then takes the six lines one at a time in 11 seconds.
Each agent's progress is on the screen, so the coordinator sees what has been read before she trusts what comes back.
Reading in the open. Chart Reader and Therapy History Builder are done. Criteria Matcher is on the first line.
3
Five lines met, and the methotrexate step unmet
Body surface area 14%, including scalp and both palms, on the September 22 note, page 24. That meets two of the plan's three severity options. A board-certified dermatologist at the labeled dose. Fifteen weeks of Tenzira, the plan's preferred biologic, with no meaningful response, confirmed by four fills. A negative TB test from October 3.
Line 4 stays red: "No documented trial of methotrexate." The screen lists what was checked: topicals for 8 weeks and light therapy for 12 weeks are documented, and no methotrexate, cyclosporine or acitretin appears in the 46 pages or the specialty pharmacy fills. It offers two next steps: search the practice record, or ask Dr. Chen.
Criteria line by line. The payer's wording on the left, the verdict and confidence in the middle, the deciding passage with its page on the right. A gap is never marked met.
4
Any citation opens the page it came from
Priya clicks the first citation. The original consultation note opens with the passage marked, the page number and the reader's own label. She can check any verdict this way in a few seconds, before she relies on it.
The same click works for the prescriber at signing and for the practice manager at audit.
The page behind the verdict. Dermatology consult of November 18, 2024, page 4, with the deciding sentence marked.
5
"Search the practice record" finds what the export left out
Priya presses the button on line 4. The agents look through telehealth encounters and outside pharmacy claims for Jordan's record since 2024. They find two telehealth visits with Dr. Chen on January 6 and May 12, 2026, and five methotrexate fills at a retail pharmacy.
They propose the proof and wait: "Methotrexate 15 mg weekly, 18 weeks, inadequate response." Priya can read the May 12 note first. Attaching is her choice.
The search and what it found. Each step of the search is listed, with its source, and nothing joins the chart until a person attaches it.
6
Attached and re-checked: six of six
The chart is now 51 pages in 11 documents. Line 4 turns green at 99% in the sample, with three citations: methotrexate from January 6 to May 12, stopped for inadequate response and a rise in ALT, a liver enzyme, to 2.4 times the upper limit, on pages 47 and 49, and five retail fills on page 51.
The Criteria Matcher only uses proven passages, so the green line rests on the notes it can quote.
Six of six. The pack on the right now offers "Build the submission pack". It stays locked while any line is unmet or unclear.
7
One click builds the form, the letter and the pages
The Form Filler completes the payer form at 32 of 32 fields and the electronic question set at 14 of 14, each answer cited. The Letter Drafter writes a one-page letter of medical necessity in Dr. Chen's voice, with 13 citations. The pack carries 17 of the 51 chart pages from 9 documents, with the proving passage marked on each.
This is the point where the work stops being Priya's. The next button reads "Send to Dr. Chen to sign and submit".
The ready-to-submit pack. Built only from proven lines. 17 pages go to the plan out of 51, in keeping with minimum necessary.
8
A letter where each clinical statement carries a number
The letter gives the request, the severity with its date, a treatment history table and the reasoning. Each number in the text leads to its chart page. The history table shows four earlier therapies, with dates, length and outcome.
No promotional wording appears, and the drafter claims nothing beyond the chart. If Dr. Chen disagrees with a sentence, she changes it, and the change is on the record.
Every statement cited. Numbers beside the text link to the chart pages, and the treatment history table is what a reviewer reads first.
9
Dr. Chen attests and signs between patients
The signing view shows what she is signing: 6 of 6 criteria, the form, the letter and 9 cited documents. Nothing goes to the plan until she signs. She ticks an attestation that she has reviewed the request, the letter and the attached records, that they are accurate, and that Veltrimab is medically necessary for this patient. She can also send it to her signature folder for later.
This setting is locked on, for every request, in the product.
The prescriber decides. A person with a license reads, attests and signs. Agents cannot press this button.
10
Sent electronically, and the decision lands on the same panel
After the signature, the Status Watcher sends the form, the letter and the 17 cited pages by ePA and watches the clock. In the sample, Crestline records its decision minutes later: approved, CH-26-884213, valid 6 months to April 6, 2027, 0.7 days from prescription.
An approval this fast is the sample's result on a request with nothing missing. Your plans will behave as they behave, and the deadlines in section 04 are what you can hold them to.
The plan's decision. The request, signature and approval sit on one panel with the record behind them.
16 · Unmet, unclear, asked, denied
Harder requests: an expedited Part D case with an unclear line, a plan's question, and an appeal that answers a misread trial
In shortMost mornings are not a clean six of six. The same screens handle a lab out of date, a statement a person must confirm, a plan asking for one more document, and a denial built on the wrong page. In each, an agent proposes and a named person decides.
Theo Lindqvist: a stale liver panel, and steroid dependence stated without dates
Theo, 67, has Crohn's disease and a Silverpine Medicare Advantage plan, with an expedited Part D request. The rule gives the plan 24 hours once it receives the request, which section 04 cites.10 Six of the 8 lines are met. His liver tests are from April 28, 162 days ago, and the plan allows 90. One click drafts a panel order for his gastroenterologist, Dr. Lena Ortiz, to sign, with "Ask Dr. Ortiz" beside it. A lab order is her decision.
Line 4 is unclear. The note says steroid-dependent and records no taper dates, so the Criteria Matcher's confidence falls to 84%. Below the practice's 90% setting, a person must look, and Dr. Ortiz still reads and signs the whole request at the end. The pack stays locked until both lines are settled.
Unclear and unmet are different states. Unclear waits for a person's judgment. Unmet says what is missing and what to do. The liver panel is 162 days old against a 90-day rule.
Samuel Okoro: Larkfield Mutual asks for a date
The plan asks for documentation of a topical calcineurin inhibitor trial of at least 4 weeks. The answer is already in the chart, on page 9. The banner shows the question, the citation and a reply button. The Status Watcher has drafted the reply, and it waits for a person. The practice's clock on this one reads "Reply by Oct 9 to keep it open".
A question with its answer beside it. The cited page is one click away. The reply is drafted, and nothing is sent until a person decides.
Rafael Duarte: a denial that read the week-8 check-in
Northgate Rx denied Dravenzo on September 30, because "the records show a TNF blocker trial of 8 weeks". TNF blockers are a class of drug designed to neutralize a protein behind inflammation. The Status Watcher compares that reason with the chart: the 8 is from a check-in visit, and the note of September 15 records 14 weeks with inadequate response. Four 28-day fills from June 9 to September 1 agree. The policy asks for 12.
The Letter Drafter writes the first-level appeal in Dr. Omar Haddad's voice. It answers that one reason, with both pages cited, and asks the plan to overturn its denial. It waits for his signature. The list shows the appeal window, 180 days from the denial, ending March 29.
An appeal aimed at the stated reason. It quotes the denial, says what was misread, and cites the note and the fills. The signature line waits for Dr. Haddad.
17 · Screens, agents, sign-offs
Beyond the criteria screen: the queue, the evidence map, the payer form, plan versions, the dashboard and who signs what
In shortAround the criteria screen sit the request list, a workspace for each request, a list of approved plan policies, a practice dashboard and the settings. Six agents read and draft. People confirm, approve versions and sign.
The request list. Every request with its criteria bar, stage, clock and prescriber. Filter by what needs you, what is ready to sign and what is with the plan. The Part D request's 24-hour clock stands out in red.
Criteria linked to evidence. In this rheumatoid arthritis request, each of the nine criteria connects to the passage that proves it. The source page stays open at the right, and the coordinator can mark a line "Not proven".
The payer form. Pre-filled from proven evidence, each clinical answer cited. A field with no evidence is left empty and flagged.
The activity record. Who or what did each thing, with the time. Agents are marked as agents.
Approved policy versions only. Crestline's new version arrived October 6 and waits for a person. Until then, the matcher keeps version 2026.10. The clock on this screen, 72 hours under a state rule, belongs to the sample policy. Real commercial clocks vary, as section 04 explains.
The practice dashboard, on sample data. Prescription to decision, first-pass approval, gaps caught early and where the hours go. The 1.2 days and 84% are the solution's design targets, shown as sample results. They are no benchmark and no promise.
The practice's own rules. The prescriber's signature is locked on. The lab window, the fill check and the confidence below which a person checks are settings, and each change goes on the audit trail. Sharing with a support program is status only, with consent, or off.
On the sample dashboard, most of the 28.8 hours from prescription to decision belong to the plan

Three design targets: 1.2 days to a decision, 84% first-pass approval, 24 minutes to verdicts
The solution data states three design targets: 1.2 days median from prescription to the plan's decision, 84% of requests approved the first time they are sent, and 24 minutes from chart in to every criterion met, unmet or unclear. They have not been measured at a customer. Part C helps you work out your own starting point.

What a specialty PA denial costs your practice: rework hours, a queue that never clears and patients who wait or walk away
In shortYou will not find a published cost per drug prior authorization. You can measure yours in a week, from your denial letters, your staff's time and your own dates from prescription to first dose. Start with the numbers below for context, and replace them with yours.

Of last year's prescriptions needing PA, how many have no first dose six months on?
For a drug maker's patient services team, the same six rows apply, with one change: you see few of these numbers directly. Ask practices for counts, with their agreement and no patient details.
What a denial log never shows: patients who drift, prescribers who give up, a coordinator who leaves
Patients who drift awayA patient told "the plan said no" may stop asking. In one survey, 12% of PAs led to delaying or abandoning treatment.41
Prescribers who change what they writeWhen a drug is hard to get, some doctors stop prescribing it. That choice is invisible in any denial log.
Your coordinator's knowledgeIf one person knows which fax line works at each plan, a resignation is an operational risk.
Your name on a weak letterA prescriber whose letters say more than the chart loses standing with reviewers, and carries the exposure described in section 08.
19 · Your return on PA support
What PA support software could return on your request volume: hours, fewer denials and days back for patients
In shortValue comes from four places: hours on each request, denials that never happen, fewer days a patient waits, and an audit record that already exists. The calculator counts the first three and is yours to fill in. Every default marked illustrative is an assumption, and the formulas are printed.

Patient days back, not valued0
Time = requests × minutes saved ÷ 60 × hourly cost. Rework = requests × fall in denial rate × rework hours × hourly cost. Patient days = denials avoided × days a denial adds. Total leaves out patient days, on purpose.
Try three sets of inputs. A small office with 300 requests a year and the other defaults has less to gain than the tool costs, so its decision turns on patients and staff time rather than dollars. A practice at the default 1,500 requests shows a modest positive total.
At 5,000 requests the total passes $150,000 with the tool's cost held at the default, so ask what the tool would cost at that volume. Volume is the main driver, and hours saved per request is the second. If your first-pass denial rate is already low, the hours line carries the case.
20 · Your readiness score
Can your practice automate PA yet? Score your denial log, time baseline, records and sign-offs
In shortScore each question from 0 to 2. The result says whether to build your baseline first, run a pilot, or plan the rollout. Your answers stay on this page.
1
Your request volume
Do you know how many specialty requests you send a year, by plan and by drug?
Why it mattersVolume drives the return, and the mix decides where to start.
A strong answer"About 1,500 a year, 40% biologic starts, top five plans named."
2
Your denial log
Do you record each denial with the plan's stated reason and the outcome?
Why it mattersNo public drug benchmark exists, so your log is your only way to show change.
A strong answer"Twelve months in a spreadsheet, with reason and final result."
3
Your baseline of time
Have you timed requests from prescription to first dose?
Why it mattersA vendor's "days saved" only means something against your own starting point.
A strong answer"Median 14 days on 30 patients, split into office, signature and plan."
4
Evidence outside the export
Can your staff reach telehealth notes, outside labs and retail fill history for a patient?
Why it mattersSoftware can only prove lines from records it can see.
A strong answer"Telehealth is in the record; fills come through the benefit check; labs by fax, on a known route."
5
Your plan policies
Do you hold the current policy for your top plans and drugs, with someone responsible for changes?
Why it mattersA match against an old version is confidently wrong.
A strong answer"A list for our top 20 pairs, reviewed monthly, and one named owner."
6
Who signs what
Is it written down who may draft, who reviews, who signs and who may press send?
Why it mattersA prescriber's name goes on the request. Software makes unclear roles worse.
A strong answer"Coordinators draft and may send only after a signature. Prescribers alone sign. No shared logins."
7
Privacy and vendor review
Can you review a vendor on privacy, with a business associate agreement and a named person?
Why it mattersThis tool holds full charts. Your HIPAA duties stay with you.
A strong answer"Our privacy lead reviews vendors in four weeks, using a standard checklist."
8
An owner with time
Is there someone who can spend a few hours a week on a pilot for 12 weeks, with a prescriber who will review?
Why it mattersA pilot with no owner measures nothing.
A strong answer"Our practice manager owns it, our lead coordinator runs it, and Dr. Chen reviews."

Answers on CMS-0057-F, drug deadlines, step therapy, appeals and the letter of medical necessity
In shortShort answers, each one complete by itself, for coordinators, practice managers and patient services teams.
What is prior authorization support?
Prior authorization support is the work of getting a health plan's advance approval for a prescribed treatment: reading the plan's criteria, proving each from the patient's chart, filling the form or electronic questions, drafting a letter of medical necessity, getting the prescriber's signature, sending, following up and appealing. Specialty offices do it themselves, and drug makers' patient services programs often help under strict limits.
Does CMS-0057-F apply to drugs?
No. CMS's fact sheet says the rule "does not apply to prior authorization decisions for drugs". Its 72-hour and 7-day deadlines, which began January 1, 2026, cover medical items and services. Drug requests run on other rules, such as Part D's 72-hour and 24-hour deadlines. CMS-0062-P would extend electronic prior authorization to drugs, and it was still a proposal in November 2026.
What are the CMS prior authorization deadlines for 2026 and 2027?
From January 1, 2026, impacted payers must decide non-drug requests within 72 hours if expedited and 7 calendar days if standard, excluding exchange plan issuers, and give a specific reason for each denial. First public metrics were due March 31, 2026. Patient Access, Provider Access, Payer-to-Payer and Prior Authorization APIs are generally due January 1, 2027, with dates varying by payer type.
How long does a plan have to decide a Part D prior authorization?
A Part D plan must decide a standard request within 72 hours and an expedited one within 24 hours. On an exception request, such as asking to skip a step, the clock starts when the plan receives the prescriber's supporting statement. If no statement arrives, the clock starts after 14 calendar days.
What should a letter of medical necessity include?
A useful letter of medical necessity gives the patient, member number, drug and diagnosis; the measured severity with dates; a table of earlier treatments with dates, length and outcome; the prescriber's clinical reasoning; and what the plan is asked to approve. Each statement should trace to a chart page. The prescriber reads and signs it, because it is the prescriber's own statement.
What is step therapy in prior authorization?
Step therapy is a plan's rule that a patient must try a preferred or older drug first before the plan will pay for the one prescribed. Proving it takes the drug's name, dates, length and outcome, often from visit notes and pharmacy fills. Many states regulate step therapy, but those laws generally cannot reach self-funded employer plans.
What does a prior authorization coordinator do?
A prior authorization coordinator reads the plan's policy, works through the patient's chart, fills in the form or electronic questions, chases missing records and watches the plan's deadline. The prescriber keeps the clinical decisions and signs the request. When that knowledge sits in one person's head, an absence can stop the queue.
Why are prior authorizations for biologics denied?
Common causes include missing proof of an earlier treatment, a trial shorter than the plan's minimum, a lab test outside its time window, no recorded severity score, an outdated form or a letter with no specifics. No national count by cause is published. Your own denial letters, sorted by stated reason, will show which ones matter in your practice.
How long does prior authorization take for a biologic?
Published figures vary widely. One Miami health system reported mean waits of 7.3 days on Medicare and 37 to 41.3 days on private plans for psoriasis biologics. One rheumatology center reported a median of 31 days to infusion when PA was required, and 50 days after a first denial. These are single-center studies, so time your own requests.
Is it worth appealing a prior authorization denial?
Published data suggest so, with caution. In Medicare Advantage in 2024, 11.5% of denials were appealed and 80.7% of appeals were overturned at least in part, though these figures do not separate drugs. At one rheumatology center, 82% of first denials were later approved. An appeal works best when it answers the plan's stated reason with the exact chart pages.
What should a prior authorization appeal letter say?
An appeal letter should quote the plan's stated reason for the denial and answer that reason first, with the exact visit note and pharmacy fills that show otherwise, attaching only those pages. The prescriber reads and signs it. Check the deadline too: ERISA employer plans must allow at least 180 days to appeal.
What is the difference between ePA and prior authorization support?
ePA is the electronic route that carries a plan's questions and the office's answers between systems. Prior authorization support is the work of finding and proving those answers from the chart, drafting the letter and following up. ePA makes sending faster, while the proof still has to be found and checked by someone or something.
Can a drug manufacturer's hub complete a prior authorization for a practice?
The conservative design keeps the request with the practice: the prescriber reviews and signs, and the program sees status only, with the patient's signed authorization. OIG's 2003 guidance discusses reimbursement support services, and the analysis depends on the facts, so counsel should review any program. Anyone submitting in a prescriber's name without that prescriber's review creates serious risk.
Can AI write a letter of medical necessity?
AI can draft one, and a March 2026 preprint found strong clinical content when all facts were supplied, with gaps on billing codes and approval periods. Real records are messier, and the authors warn the risk is likely higher there. The letter remains the prescriber's statement, so a clinician must read it, correct it and sign it.
Does AI used for prior authorization need FDA clearance?
The Federal Food, Drug, and Cosmetic Act excludes software for administrative support of a health care facility, including claims or billing information and determining health benefit eligibility, from the device definition. A tool that helps an office assemble evidence for a clinician's review may fit that description, while one that recommends treatment raises a different question. This is general information, so ask your counsel about your own tool.
