Prior authorization for physical therapy: 2026 reality check

Two announcements went out on the same day this spring. On May 5, CMS Administrator Mehmet Oz published a progress report: leading health plans had eliminated 11% of prior authorizations across a range of medical services. That is 6.5 million fewer requests for patients. The same day, UnitedHealthcare announced it will drop authorization requirements for 30% of the services that still carry them by the end of 2026. Its named examples include “certain outpatient therapies and chiropractic care.”

Read both from the front desk of a PT clinic and the picture splits in two. UnitedHealthcare still requires prior authorization for the entire therapy plan of care under most of its Medicare Advantage plans, in office and outpatient settings. Both stories are true at once, and the gap between them is where this year’s denials live.

What actually changed in 2026?

Three things, and none of them has removed prior authorization from a therapy visit yet.

Deadlines got real. Since January 1, 2026, CMS gives impacted payers in Medicare Advantage, Medicaid, CHIP and the federal Marketplace hard deadlines: 7 calendar days for a standard decision, 72 hours for an expedited one. The electronic prior authorization interfaces those payers must run go live January 1, 2027. If an MA plan has been sitting on your plan-of-care request for two weeks, you now have a federal deadline to cite back at them.

The pledge produced numbers. The 11% reduction CMS touted came from the voluntary commitments HHS and CMS extracted from major insurers in 2025, and plans announced the figure themselves in April. CMS has its own estimate of what the paperwork costs the people filling it out: $20 to $50 an hour and an average of 13 hours a week. That works out to nearly $34,000 and 700 hours per provider per year, by CMS’s math.

And UnitedHealthcare made a promise with a date on it. The 30% cut lands “by the end of 2026,” and UHC says a full list of dropped services will appear on UHCProvider.com before the changes take effect. Until that list publishes, “certain outpatient therapies” is a phrase, not a policy. UHC also offered its own framing of the status quo. By its telling, prior authorization touches only 2% of its medical services, and around 92% of submitted requests are approved, in under 24 hours on average. Your biller’s experience of the therapy program may read differently, which brings us to it.

Does UnitedHealthcare still require prior auth for PT?

Yes. Under UnitedHealthcare’s Medicare Advantage therapy program, prior authorization is required for physical, occupational and speech therapy delivered in office and outpatient hospital settings. The request must cover the entire plan of care, full duration and visit count included. The requirements began September 1, 2024, and extended to additional UHC plans in Arizona and California on February 1, 2026.

The mechanics decide whether your claims get paid, so here they are exactly:

• The initial evaluation needs no authorization and gets covered either way.
• On an initial request, up to 6 visits within 8 weeks are covered without a clinical review. “Initial” means the patient is new to your office, presents with a new condition, or has had a 90-plus-day gap in care. You still have to submit the authorization request for those 6 visits.
• Ask for more than 6 visits or more than 8 weeks and the plan of care goes to medical necessity review. Every extension after the initial plan needs a new request and gets reviewed in full.
• Submit within 10 business days of starting care. Miss that window and UHC may deny the claim, and you cannot balance bill the patient.

The impacted code list is not exotic. It is your Tuesday: 97110, 97112, 97140, 97164, 97530 and most of what surrounds them on a superbill.

That 6-visit window did not appear out of goodwill. APTA pushed on this program from the start, arguing that clinical review before follow-up visits would delay needed services, and UHC added the carve-out effective January 13, 2025. APTA called itself “encouraged but not satisfied,” which is about right. The review moved; the requirement stayed.

The appeal math nobody runs

Here is the number that should change your workflow more than any pledge. KFF’s analysis of CMS data found Medicare Advantage insurers made nearly 53 million prior authorization determinations in 2024 and denied 4.1 million requests, 7.7%, in full or in part. Of those denials, just 11.5% were appealed. And 80.7% of the appeals were partially or fully overturned.

Sit with that ratio. Roughly nine in ten denials go unchallenged, while more than eight in ten challenges succeed at least in part. KFF notes some overturns may simply reflect requests that were missing documentation the first time, which is its own lesson. But for a practice the operational conclusion is blunt: a denial is where the negotiation starts. A clinic that appeals clinical denials by default, eval and objective measures attached, is playing a game most of the market has forfeited.

What your front desk changes this quarter

Prior authorization is a workflow problem wearing a policy costume, and workflow is the part you control.

Flag the plans at booking. The moment a UHC Medicare Advantage patient schedules an eval, the authorization clock is already relevant. A plan type discovered when the claim bounces is six visits too late. Orion runs eligibility at booking, so the front desk sees the Medicare Advantage flag before the patient arrives.

Submit with the eval, not after it. The 6-visit window means you can start treating the same day, but the 10-business-day rule means the request cannot wait for a quiet Friday. Make the authorization submission part of closing the eval note.

Track pending auths like AR. Every open request needs an owner, a submitted date, and the 7-day decision deadline on it. Visits delivered past an expired or absent auth are the denials you count in your denial rate three months later and cannot collect.

Appeal clinical denials by default. The KFF numbers are the argument. Build one appeal template per payer, attach objective progress data, and send it within the week.

When UHC’s end-of-2026 list publishes, check your codes against it before you change anything. If outpatient therapy makes the cut, retire the tracker for those plans and celebrate. Until the list exists, the practices that win this year are the ones that treat every pledge as weather and their own authorization workflow as the roof.
