Prior Authorization Turnaround Times: What the Data Shows by Payer Type
Payers now publish how fast they decide, and the medians look fast: about a day. Your coordinator's week says otherwise. Both are true, and the gap between them is where patients actually wait.
How long does prior authorization take? By rule, since January 2026, Medicare Advantage, Medicaid, and CHIP plans must decide standard requests within 7 calendar days and expedited ones within 72 hours. In the first payer-posted data, median decisions ran about one day. The wait your team feels also includes everything before a complete request reaches the payer.
Key takeaways
- Since January 1, 2026, CMS-0057-F caps Medicare Advantage, Medicaid, and CHIP decisions at 7 calendar days standard and 72 hours expedited.
- KFF's read of 2025 payer-posted metrics: median standard decisions of about 1 day in Medicare Advantage and Medicaid managed care (August 13, 2026).
- Yet 95% of physicians say prior authorization delays access to necessary care (AMA survey, released May 13, 2026).
- Employer plans under ERISA: 15 days for a pre-service claim, plus one 15-day extension, and 72 hours for urgent care.
- Measure your own order-to-decision time. The free prior auth tracker has the date columns already.
In August 2026, KFF read the first prior authorization metrics insurers were required to publish and found median standard decisions of about one day in Medicare Advantage. Three months earlier, 95% of physicians in the AMA's survey said prior authorization delays access to necessary care. Both numbers are real. The useful part is the distance between them, and most of it sits on your side of the fax machine.
How long does prior authorization take? The legal clocks by payer
Start with what the rules allow, because the answer to "how long does prior authorization take" depends first on who the payer is. The clocks below are outer limits. Plans may decide faster, and many state laws set shorter limits for the plans they regulate.
| Payer type | Standard | Expedited | Source |
|---|---|---|---|
| Medicare Advantage | 7 calendar days | 72 hours | CMS-0057-F, since January 1, 2026 |
| Medicaid and CHIP, fee-for-service and managed care | 7 calendar days | 72 hours | CMS-0057-F, since January 1, 2026 |
| Federal exchange (ACA) plans | 15 days | 72 hours | Existing federal rules; CMS says the new limits do not apply |
| Employer plans under ERISA | 15 days, one 15-day extension | 72 hours | 29 CFR 2560.503-1 |
| Medicare Part D drugs | 72 hours | 24 hours | 42 CFR 423.568 and 423.572 |
| Traditional Medicare, outpatient department services | 7 calendar days | 2 business days | CMS, since January 1, 2025 |
CMS's own FAQ is explicit that the 72-hour and 7-day limits apply to Medicare Advantage, Medicaid, and CHIP, and not to qualified health plans on the federal exchanges. Those plans post metrics under the same rule but keep the older decision limits. Most commercial employer coverage sits outside CMS-0057-F entirely, and KFF puts 67% of covered workers in self-funded plans (2025), which state laws do not reach.

CMS-0057-F required affected plans to post nine prior authorization metrics for 2025 on their websites by March 31, 2026, including average and median time from submission to decision. Forvis Mazars, citing AuthDenied data, reported that 92% of required plans had posted by July 21, 2026. KFF then analyzed 14 large insurers covering about 71 million enrollees.
| Market | Standard | Expedited | Insurer range, standard |
|---|---|---|---|
| Medicare Advantage | About 1 day | About 0.4 days (about 10 hours) | Under 1 day to 2 days |
| Medicaid managed care | About 1 day | About 0.8 days (about 19 hours) | 1 to 4 days |
| ACA Marketplace | About 0.9 days | About 1 day | Under 1 day to 4 days |
Standard prior auth decisions in 2025: median days against the legal maximum
Teal: median days to a decision. Grey: the legal maximum that applied in 2025. Since January 1, 2026 the Medicare Advantage and Medicaid maximum is 7 calendar days.
KFF found median standard decisions of about one day in Medicare Advantage and Medicaid managed care in 2025, far inside the 14-day limit that applied that year. KFF also flagged the catch: plans report only medians and averages, so nobody can tell from the postings how many decisions blew past the deadline.
| Market | Standard requests denied | Denials overturned on appeal (standard) |
|---|---|---|
| Medicare Advantage | 12% | 67% |
| Medicaid managed care | 14% | 47% |
| ACA Marketplace | 18% | 43% |
Method matters when you compare sources. Forvis Mazars, using AuthDenied's plan-level data, reported a median plan denial rate of 7.2% in Medicare Advantage and about 12% to 14% in Medicaid managed care, CHIP, and marketplace plans, with only 7.3% of denials appealed. Different denominators, same lesson: denials are uncommon per request, rarely appealed, and often reversed when someone does.
Why a one-day median still feels like a week
Picture a Thursday at a hypothetical three-physician orthopedic practice. A physician orders a lumbar MRI at 2 p.m. The order sits in the inbox until Monday, the visit note is not signed until Tuesday, and the request goes to the health plan on Wednesday, which bounces it to its imaging vendor.
The vendor approves it Thursday, one day after receiving it. The payer's posted metric records a one-day turnaround. The patient waited eight days for an answer, and seven of them happened before the payer ever saw the request.
| Delay | Why the payer clock misses it |
|---|---|
| Order to identification | No request exists yet |
| Gathering notes, imaging, failed-therapy history | The clock starts on receipt of the request |
| Submitting to the wrong place | Benefit managers such as EviCore, Carelon, and Evolent run separate front doors |
| Requests for more information | Missing information can delay or deny; under ERISA the clock can pause while the patient side responds |
| Decision to scheduling | The payer is done; the practice is not |
Two more effects pull the median down. Many simple requests are approved in real time, which is why some plans post median decision times of zero days. And the complex requests that consume your coordinator's week, advanced imaging, surgery, specialty drugs, sit in the tail that medians hide. The imaging piece, with its benefit managers, is covered in the MRI and CT prior authorization guide.
What physicians report
The AMA survey measures burden, not minutes, and the burden is large: about 40 requests and 13 hours of physician and staff time per physician per week, with 40% of practices employing staff who work exclusively on prior authorization. In the same survey, 26% of physicians said prior authorization had led to a serious adverse event for a patient. The full breakdown is in the prior authorization statistics roundup.
Patients feel it too. KFF's July 2025 poll, cited in its August 2026 analysis, found 24% of insured adults said their insurer had delayed a requested service, treatment, or medication in the past two years.
A one-day median and a 95% delay rate are not contradictory. One measures the payer's desk. The other measures the whole path, from the order to the appointment.
Reading one payer's numbers
Each plan posts its own report, often one per contract. Here is one large Humana Medicare Advantage contract's 2025 posting, to show what the numbers look like up close.
| Measure | Standard | Expedited |
|---|---|---|
| Requests | 1,303,837 | 10,354 |
| Approved | 92.98% | 82.64% |
| Denied | 7.02% | 17.36% |
| Mean time to decision | 1 day | 9 hours |
| Median time to decision | 0 days | 0 hours |
Humana's posting shows 1,561 appeals on that contract in 2025, with 55.73% approved after appeal. A median of zero days tells you most requests clear almost instantly. The mean of one day, and nine hours for expedited, tells you a slower tail exists without telling you how long it is. How to read these reports for your own payers is walked through in the guide to payers' published prior auth metrics.
The practice-side clock you control
You cannot make a payer decide faster than it does. You can control everything before submission, and that is usually the bigger number.
| Stage | Owner | Target |
|---|---|---|
| Order flagged as needing authorization | Front desk or scheduler | Same day as the order |
| Clinical documentation assembled | Prior auth coordinator with the clinician | Within 1 business day |
| Submitted to the correct payer or vendor | Prior auth coordinator | Within 1 business day of complete records |
| First status check | Prior auth coordinator | 48 hours after submission |
| Patient scheduled after approval | Scheduler | Same day as the decision |
That is the logic behind the 48-hour prior auth pipeline: get a complete request out the door within two business days of the order, then follow up on a fixed cadence. Most of the eight days in the example above disappear without any payer changing anything.
A follow-up cadence built on real deadlines
Now that the outer limits are known, your follow-up cadence can key off them. A Medicare Advantage request with no decision on day 7 is no longer just slow. It is past the regulatory limit, and the call you make sounds different.
| Payer type | Check status | Escalate |
|---|---|---|
| Medicare Advantage, Medicaid, CHIP (standard) | Day 2 and day 5 | Day 7: past the CMS-0057-F limit |
| Any CMS-0057-F payer (expedited) | 24 hours | 72 hours |
| Employer plan under ERISA (pre-service) | Day 2, day 5, day 10 | Day 15, unless an extension was noticed |
| Traditional Medicare outpatient department | Day 3 | Day 7 (standard); 2 business days (expedited) |
Ask for expedited review when it is warranted, and put it in writing. Under 42 CFR 422.570, a Medicare Advantage plan must expedite a physician's request when the physician indicates the standard timeframe could seriously jeopardize the patient's life, health, or ability to regain maximum function. The expiration side of the same problem, approvals that lapse before the visit, is covered in the 48h, 5d, 10d cadence guide.
Measure your own turnaround
Payer postings tell you about their desk. Your tracker tells you about yours. Log four dates per request, by chart number and never by patient name: ordered, submitted, decided, scheduled.
The free prior authorization tracking spreadsheet has those columns. Once a month, compute the median days from order to submission and from submission to decision, by payer. Two numbers per payer, twelve times a year, is enough to see a trend.
Monthly turnaround report, demo tracker (median days, chart numbers only)
| Payer | Order to submission | Submission to decision | vs 2-day practice median |
|---|---|---|---|
| Payer A | 1.5 | 2 | At median |
| Payer B | 1.0 | 1 | Faster |
| Payer C | 2.0 | 6 | 3x the median |
| Payer D | 1.0 | 2 | At median |
| Payer E | 3.5 | 2 | Your side is slow |
If order-to-submission is the bigger bar, the fix is internal and fast. If one payer's decision bar is far above its own posted median, you have evidence for a provider relations call. Either way, you are arguing from your numbers. For the full operating method, start with the prior authorization operations guide.
- Find the posted 2025 prior authorization metrics for your top three payers and note their median standard and expedited times.
- Add ordered and submitted date columns to your tracker if they are missing.
- Filter pending Medicare Advantage and Medicaid requests older than 7 calendar days and call each one today.
- Pick one stage from the practice-side table and assign it a named owner and a target.

Frequently asked questions
How long does prior authorization take?
Since January 1, 2026, Medicare Advantage, Medicaid, and CHIP plans must decide standard requests within 7 calendar days and expedited ones within 72 hours. In payer-posted 2025 data, median decisions ran about one day (KFF, August 2026). Add the time your practice takes to assemble and submit a complete request.
What is the prior authorization turnaround time for commercial insurance?
For employer plans governed by ERISA, the federal outer limit is 15 days for a pre-service claim, with one 15-day extension allowed, and 72 hours for urgent care. State laws can set shorter limits for state-regulated plans. Check the plan documents and your state's rules.
Does traditional Medicare have prior authorization turnaround times?
Yes, where it uses prior authorization. In the hospital outpatient department program, CMS cut standard reviews from 10 business days to 7 calendar days for requests submitted on or after January 1, 2025, and expedited reviews stay at 2 business days.
What qualifies as an expedited prior authorization?
In Medicare Advantage, a plan must expedite a physician's request when the physician indicates the standard timeframe could seriously jeopardize the patient's life, health, or ability to regain maximum function (42 CFR 422.570). Expedited decisions are then due within 72 hours. Use it when the clinical facts support it, and say so in writing.
Where can I see a payer's prior authorization turnaround times?
Plans covered by CMS-0057-F must post prior authorization metrics on their websites each year, including average and median time from submission to decision. The first postings, for 2025, were due March 31, 2026, and Forvis Mazars, citing AuthDenied data, reported 92% of required plans had posted by July 21, 2026.
