UnitedHealthcare’s Oct. 1 Prior Auth Cut: Florida Fine Print

On September 1, UnitedHealthcare told physicians it would stop requiring prior authorization for about 1,700 procedure codes beginning October 1, 2026, and it described the change as a 30 percent reduction in its prior authorization requirements. Four days earlier, Lee Health in Fort Myers had told the same insurer it was ending every contract it holds with the company at the end of the year, citing years of denials and more than $100 million in disputed and underpaid claims. A Florida physician should read the two stories together before deciding what October 1 actually changes in the office.

The honest answer is that it changes some things, mostly on the commercial side, and that the Medicare Advantage patients who make up 57 percent of Florida’s Medicare population will notice almost nothing.

What UnitedHealthcare Announced

Effective October 1, the company is removing prior authorization requirements from roughly 1,700 codes across its commercial, Medicare Advantage, Community Plan (Medicaid), Individual Exchange, and Oxford products, and it frames the change as part of an effort to “reduce administrative work, remove barriers that can delay care and give you more time to focus on patient care.” The company had pledged in the spring to cut 30 percent of its prior authorization volume by the end of 2026, following a 20 percent cut to commercial requirements in 2023.

The affected services are real. According to the code lists and trade coverage of them, the cuts reach lesion excisions, fracture care, joint injections, arthroscopies, colonoscopies and other endoscopies, biopsies, hernia repairs, soft tissue tumor removals, and a long list of genetic and molecular tests, along with physical, occupational and speech therapy, home health, durable medical equipment, and some chiropractic care.

What the Numbers Say

The number that matters to a practice is how many codes come off the list for the plans it bills. Healthcare Dive broke the total down from the company’s own documents: more than 800 codes for commercial plans, about 940 for Individual Exchange plans, about 1,400 for Oxford plans in New York, New Jersey and Connecticut, and roughly 120 for Medicare Advantage and dual special needs plans. Medicaid lists vary by state. Wendell Potter, the former Cigna executive who now writes about insurer practices, went through the Medicare Advantage document and counted about 70 distinct codes printed twice.

Potter made a second point that is easy to miss. UnitedHealthcare has said for two years that it requires prior authorization on only about 2 percent of the services it covers, and that roughly 92 percent of requests are approved within 24 hours. A 30 percent cut to 2 percent is six tenths of one percentage point of covered services. The codes that stay on the list, by his reading, include specialty and injectable drugs, GLP-1 medications, most oncology drug regimens, and many cardiac device implants, which is to say the high-cost items where a denial changes a treatment plan.

A colonoscopy that no longer waits on a portal submission is a real gain. It remains true that the 30 percent figure describes the insurer’s administrative volume rather than the physician’s clinical exposure, and those are different things.

The Florida Test Case

Lee Health operates five hospitals in Lee County, including Golisano Children’s Hospital of Southwest Florida, plus the Lee Physician Group, in a county of roughly 800,000 people. On August 28 it announced that every Lee Health hospital and physician will be out of UnitedHealthcare’s network on January 1, 2027, for employer-sponsored, individual, and Medicare Advantage plans. Medicare Supplement policies sold under the UnitedHealthcare and AARP names are not affected, because those pay on Original Medicare’s terms.

The system’s public explanation did not rest on rates alone. Lee Health said that about one third of its medical necessity denials trace to UnitedHealthcare’s Medicare Advantage plans, that the insurer owes it more than $100 million in disputed and underpaid claims, and that the two organizations “have fundamentally different priorities.” UnitedHealthcare answered that Lee Health “unexpectedly issued a notice to end our network relationship at the conclusion of our current contract without any advance notice or discussions,” and said it would rather keep negotiating.

What is different in Fort Myers is that a nonprofit system put the denial rate in writing, in a letter to its own patients, six weeks before Medicare open enrollment opens on October 15. The announcement and the letter describe the same review process from two sides of the table, and the numbers in the letter are the ones the October 1 lists do not reach.

Why It Matters for Florida Physicians

Florida had 5,287,658 Medicare beneficiaries in January 2026, and 57 percent of them were in Medicare Advantage plans, above the national figure of 55 percent. UnitedHealth Group holds 26 percent of Medicare Advantage enrollment nationally. One third of Florida’s Medicare Advantage enrollees are in special needs plans, the dual eligible and chronic condition products where the company’s October list is thinnest.

There is also a federal clock running that has nothing to do with the insurer’s pledge. The CMS Interoperability and Prior Authorization final rule took effect for Medicare Advantage plans on January 1, 2026. Since then, plans have been required to decide expedited requests within 72 hours and standard requests within seven calendar days, to give a specific reason for every denial, and to post their approval, denial and appeal metrics publicly, with the first postings due by March 31, 2026. Electronic prior authorization interfaces follow on January 1, 2027. The HHS Office of Inspector General found in 2022 that 13 percent of the Medicare Advantage prior authorization denials it sampled met Medicare coverage rules, and that 18 percent of payment denials met both Medicare and plan billing rules.

What Florida Physicians Should Do Now

1. Pull the October 1 code lists for the products you actually bill. The five PDFs are posted on the UnitedHealthcare provider site, one per product line. Have your authorization staff mark which of your top 50 codes come off the commercial list, which come off the Medicare Advantage list, and which stay.
2. Do not turn off the prior authorization step in your workflow. Removal of prior authorization does not remove medical necessity review after the claim, referral requirements in HMO products, or network status, and a post-payment review will ask for the same record.
3. Read the denial data your practice already has. Lee Health could say that one third of its denials came from one insurer’s Medicare Advantage plans because someone counted. Ask your billing team for denials by payer and reason code for the last twelve months.
4. Tell your Medicare Advantage patients what is changing before open enrollment. Between October 15 and December 7, patients in Lee County and anywhere else with an unresolved network dispute will be choosing plans. A notice about which plans your practice will accept in 2027 is a service to them. None of this constitutes legal advice, so have your practice attorney review any patient communication about a specific insurer before it goes out.
5. Put the denial figures in front of your county medical society and the Florida Medical Association. A physician organization can ask the Office of Insurance Regulation and the state’s congressional delegation a question no single practice can: whether Medicare Advantage denial rates in Florida match what plans are now required to publish, and what the state intends to do if they do not.

The Bigger Picture

Prior authorization was built as a check on physician judgment, and every reform of it so far has been announced by the party that holds the check. That is why a 1,700-code list and a hospital system’s exit letter can appear in the same month and both be accurate. The list measures what the insurer chose to stop reviewing, and the letter measures what happened to the requests it kept. The federal rule now requires the plans to publish their side of the ledger. Our side is the denial log in the billing office, and nobody is going to read it for us.

Frequently Asked Questions

When does UnitedHealthcare’s prior authorization reduction take effect, and which plans does it cover?

The change takes effect October 1, 2026, and applies across UnitedHealthcare commercial, Medicare Advantage, Community Plan (Medicaid), Individual Exchange, and Oxford products. Each product has its own list, and the Medicare Advantage list is the shortest, at roughly 120 codes by Healthcare Dive’s count and about 70 distinct codes by Wendell Potter’s.

Does removing prior authorization mean UnitedHealthcare will pay the claim?

No. Prior authorization is one review among several. Claims remain subject to medical necessity review after the service, to network and referral rules under the patient’s product, and to the plan’s coverage policies. Practices should keep documenting as though authorization were still required.

What happens to Florida patients with UnitedHealthcare Medicare Advantage plans who use Lee Health?

Lee Health’s hospitals and physicians will be out of network for UnitedHealthcare employer, individual, and Medicare Advantage plans on January 1, 2027, unless the two sides reach an agreement. Medicare Supplement plans are not affected. Patients may qualify for continuity of care at in-network rates for a limited period through UnitedHealthcare, and Medicare Advantage members can change plans during open enrollment from October 15 through December 7.

What does federal law now require of Medicare Advantage plans on prior authorization?

Under the CMS Interoperability and Prior Authorization final rule, since January 1, 2026, Medicare Advantage plans must decide expedited requests within 72 hours and standard requests within seven calendar days, give a specific reason for each denial, and post their prior authorization metrics on their websites each year. Electronic prior authorization interfaces are required beginning January 1, 2027. The decision timeframes do not apply to drug requests.
