UnitedHealthcare Is Dropping Prior Authorization for 1,700 Codes. Only About 120 Apply to Medicare Advantage and Dual-Eligible Plans
UnitedHealthcare's announcement that it is cutting prior authorization on 1,700 codes sounds like a breakthrough for Medicare Advantage members, but the fine print reveals a much narrower reality and a new set of hurdles that could still leave claims unpaid.

A UnitedHealthcare Medicare Advantage member reads that her insurer is dropping prior authorization on 1,700 medical codes starting October 1 and hears one thing: the wall between her and the procedure her doctor ordered just came down.
The impact that applies to her is much smaller. Of the roughly 1,700 codes, approximately 120 are associated with Medicare Advantage and dual special needs plans, according to Healthcare Dive. The Center for Medicare Advocacy, which reviewed UnitedHealthcare’s posted lists, counted about 70 codes on the general Medicare Advantage and D-SNP list, with additional codes applying only to D-SNPs. A member who is not dual-eligible should not assume all 120 are hers.
And for the codes that do apply, removing the preapproval step does not commit UnitedHealthcare to paying the bill.
If you are on Original Medicare with a Medigap policy, this does not touch you. Original Medicare rarely requires prior authorization, and this is a UnitedHealthcare policy change, not a Medicare rule change. The person most affected is the Medicare Advantage or D-SNP member about to schedule something this fall.
What Changes on October 1
UnitedHealthcare told providers on September 1 that it is eliminating prior authorization on roughly 1,700 CPT codes, about 30% of its preapproval requirements across commercial, Medicare Advantage, Medicaid, and ACA plans. It follows a pledge this spring to cut 30% of prior authorizations by the end of 2026.
Across all plan types, the codes span oncology, cardiology, orthopedic and musculoskeletal procedures, genetic and lab testing, chiropractic care, physical, occupational and speech therapy, home health services, and durable medical equipment. That list describes the full announcement, not the Medicare Advantage subset. Whether a specific procedure sits on the MA list is a question for her doctor or her plan, not an assumption to draw from the categories.
A company spokesperson said UnitedHealthcare focused on services with proven clinical efficacy where approval rates are consistently high, meaning it was already saying yes most of the time and the paperwork was largely friction. Critics read that same fact differently. “A lot of what’s on the list is low-stakes,” health care advocate Wendell Potter told MedPage Today. “Removing prior authorization from codes nobody uses generates a big number at no real cost to UHC.”
Prior Authorization Is One Gate. There Are Others.
Removing prior authorization eliminates one approval step. It does not remove network rules, referral requirements, medical-necessity review after the fact, or cost sharing. Before assuming a service on the cleared list is covered, a member still has to confirm three things.
- The provider is in-network. An out-of-network specialist on an HMO plan can leave her responsible for the full bill regardless of what the CPT code says.
- Any required referral is on file. Many Medicare Advantage HMOs still require a primary care referral to see a specialist. Dropping prior authorization on the procedure does not remove the referral needed to get in the door.
- The service meets medical-necessity standards. Plans can still deny claims after the fact when documentation does not support the procedure. Prior authorization put that judgment at the front end. Removing it moves the judgment to the back end.
Context on denials is worth holding onto. KFF estimated that plans denied between 12% and 18% of standard prior authorization requests in 2025, with Medicare Advantage at 12%. UnitedHealth had the highest Medicare Advantage denial rate at 17%. Separately, the Center for Medicare Advocacy reports that skilled nursing facility denials and premature discharges remain the top complaint it hears from Medicare Advantage enrollees, which is not what this announcement addresses.
Your Cost Sharing Did Not Change
Nothing here lowers what a member owes when she uses covered care. And her costs are not Original Medicare’s costs. Medicare Advantage plans set their own hospital copays, skilled nursing charges, and coinsurance, subject to Medicare rules and the plan’s annual out-of-pocket maximum. The only reliable source for those numbers is her plan’s Summary of Benefits, not the Original Medicare figures that get quoted every fall. She continues to pay the Part B premium, $202.90 in 2026, under either arrangement.
What to Do Before You Schedule
- Request a pre-service organization determination if you need certainty. Calling the number on the back of your card gets you useful information about network status, referral requirements, and estimated cost sharing. It does not get you a binding answer. A verbal yes and a reference number are not a guarantee of payment. A formal organization determination is the mechanism that produces one.
- Know what the enrollment windows can and cannot fix. Switching during the Annual Election Period, October 15 through December 7, changes coverage on January 1. It will do nothing for a procedure scheduled this fall. The Medicare Advantage Open Enrollment Period runs January 1 through March 31. If network or referral walls are a recurring problem, model Original Medicare plus a Medigap policy against your current plan for a realistic sick year, not a healthy one. Switching back later usually means applying for Medigap under medical underwriting, so the window to move without health questions is narrower than most enrollees realize.
The prior-authorization cut is a real improvement for the services it touches. It is not a coverage guarantee, and for most Medicare Advantage members it touches considerably less than the headline number suggests.
