Revenue Cycle & Patient Access
Prior Authorization Denials: What Practice Managers Can Actually Control
Who this is for: practice managers, billing managers, and the medical billing companies, RCM vendors, and practice management software companies who build tools for them. This is about the business and administration of prior authorization, not medical necessity decisions or clinical judgment.
If you manage a practice, you already know the feeling. A prior auth comes back denied, the patient is sitting in your waiting room or calling for the third time this week, and you cannot tell them how long the fix will take because you do not fully control it either.
That is the honest starting point. Some of what drives prior authorization denials is yours to fix. A real share of it is not, and no amount of extra effort on your end changes it. This post draws the line between the two, so your team spends its time on the part that actually moves.
Practice managers control submission accuracy, appeal follow-through, and knowing which rules apply to which payer. They do not control a payer's medical necessity criteria, which patients a federal rule actually covers, or the fact that the first decision on a claim is often overturned on appeal.
What Prior Authorization Is Actually Costing Practices
The American Medical Association's 2025 Prior Authorization Physician Survey found that physicians and their staff complete an average of 40 prior authorizations per physician every week, and spend about 13 hours a week on the process, based on a survey of 1,000 practicing physicians fielded in December 2025 (AMA, 2025 Prior Authorization Physician Survey).
The same survey found that 95 percent of physicians report prior authorization delays access to necessary care, and 79 percent report it leads patients to abandon their recommended treatment at least sometimes. More than one in four physicians, 26 percent, report that prior authorization has led to a serious adverse event for a patient in their care. Ninety-four percent report that prior authorization increases physician burnout.
Those numbers describe the whole system, not any one practice's mistakes. Your team can run a flawless intake process and still live inside those percentages, because the volume and the friction are largely set by the payers, not by you.
This is a different problem from what shows up in clean claim rate, which measures claims after they are submitted. Prior authorization happens before the claim exists at all, which is exactly why it can stall a patient's care before billing is ever involved.
The Part You Do Not Control
The payer sets the criteria, and it can differ by plan
A denial reason that holds up for one payer's policy can be wrong for another. Medicare Advantage plans, Medicaid managed care plans, and commercial payers each publish their own medical necessity criteria, and those criteria are not the same across payers even for the identical procedure. Your team can document perfectly and still get denied because the specific payer's specific policy called for something different. That is a payer decision, not a documentation failure.
The new federal rule does not reach every patient in your waiting room
CMS finalized the Interoperability and Prior Authorization final rule, CMS-0057-F, on January 17, 2024. Starting January 1, 2026, it requires certain payers to send prior authorization decisions within 72 hours for expedited requests and seven calendar days for standard requests, and to give a specific reason when they deny a request (CMS, CMS Interoperability and Prior Authorization Final Rule Fact Sheet, 2024).
That rule reaches Medicare Advantage plans, Medicaid fee-for-service and managed care, the Children's Health Insurance Program (CHIP) fee-for-service and managed care, and qualified health plans sold on the federally facilitated marketplace. It does not reach traditional Medicare, and it does not reach most employer-sponsored commercial insurance. If the bulk of your denials come from a commercial payer your patients get through their job, this rule does not touch that relationship at all. Do not build your 2026 plan around a fix that was never aimed at your biggest source of friction.
The appeal usually works better than the first decision, and that is the payer's pattern, not yours
When Medicare Advantage organizations denied requests for skilled nursing facility admission in June 2024, they overturned 95 percent of those denials once the enrollee or provider appealed, according to a federal audit of 19 Medicare Advantage organizations (HHS Office of Inspector General, Report OEI-09-24-00331, 2026). Separately, KFF's analysis of 2024 Medicare Advantage data found that of the 4.1 million prior authorization requests denied that year, only 11.5 percent were appealed, and 80.7 percent of those appeals overturned the original denial (KFF, Medicare Advantage Insurers Made Nearly 53 Million Prior Authorization Determinations in 2024, 2026).
Read that gap again. Most denials that get appealed get overturned. Most denials never get appealed at all. That gap is where the payer's process, not your practice's effort, decides the outcome for the large majority of patients who never see an appeal filed on their behalf.
The Part You Do Control
Closing the appeal gap is the single biggest lever you have
Given the OIG and KFF numbers above, the practices losing the most are not the ones with weak documentation. They are the ones without a staffed, tracked process for actually filing the appeal once a denial lands. If your team appeals a fraction of what it should, building or buying the staff time to appeal consistently is the highest-return fix available, because the odds are already in your favor once you file.
Getting the submission right the first time
Clerical accuracy is still yours to own: the correct National Provider Identifier (NPI), current ICD-10 and CPT codes, complete clinical documentation that supports medical necessity under that specific payer's policy, and submission through the channel that payer actually requires. None of this guarantees approval, but it removes the denials that have nothing to do with the patient's actual clinical need and everything to do with a missing field.
Knowing which rule applies to which patient
Because CMS-0057-F only reaches certain payers, your team needs to know, patient by patient, which set of rules is in play. A Medicare Advantage patient's plan is on the clock for 72-hour and 7-day decisions starting in 2026. A patient on a self-funded employer plan is not covered by that clock at all. Treating every prior auth as if the same federal deadline applies sets your front desk up to promise a turnaround time you cannot back up.
Tracking where gold carding actually applies, and where it does not
Several states have passed laws that exempt high-performing providers from prior authorization on specific services, often called gold carding, typically for providers whose requests are approved 90 percent of the time or more. In practice, the reach is still narrow: the AMA's 2025 survey found that only 5 percent of physicians report currently contracting with a health plan that offers this kind of exemption (AMA, 2025 Prior Authorization Physician Survey). It is worth checking whether your state and your top payers qualify, but do not plan your denial strategy around an exemption that reaches one in twenty physicians today.
What This Means If You Build or Sell to Practices Like This
If your product or service touches prior authorization, the practice managers you sell to are not looking for someone to tell them the system is broken. They already live in it 13 hours a week. What earns their attention is a tool or a service that closes the appeal gap, tracks which federal or state rule actually applies to which patient, and is honest that CMS-0057-F does not solve the commercial-payer half of their problem. Content built around what a practice manager actually has to sort out day to day reads as credible to this audience in a way that a generic "reduce denials" pitch does not.
Frequently Asked Questions
Does the new CMS prior authorization rule apply to all my patients' insurance?
No. CMS-0057-F applies to Medicare Advantage, Medicaid, CHIP, and qualified health plans sold on the federally facilitated marketplace. It does not apply to traditional Medicare or to most employer-sponsored commercial insurance.
Should my practice appeal every prior authorization denial?
Federal data on Medicare Advantage suggests appealing is worth the staff time far more often than practices currently do it: 80.7 percent of appealed denials were overturned in 2024, but only 11.5 percent of denials were appealed at all, per KFF's analysis of CMS data.
What is gold carding, and does my practice qualify?
Gold carding is a state-level program that exempts providers with high prior authorization approval rates, usually 90 percent or higher, from needing prior authorization on specific services. Availability varies by state and by payer, and as of the AMA's 2025 survey, only about 5 percent of physicians reported currently having this kind of exemption with a health plan.
When do the new prior authorization turnaround times take effect?
The 72-hour expedited and 7-day standard decision timeframes, along with the requirement to give a specific denial reason, apply beginning January 1, 2026, for the payers covered by CMS-0057-F.
The Bottom Line
Prior authorization denials come from two different places: a system-level process that sets its own criteria and its own pace, and a practice-level process your team runs every day. You cannot fix the first one by working harder. You can fix the second one, and the data says the appeal gap is where the fix pays off fastest.
