UnitedHealthcare denial appeals

UnitedHealthcare is the largest U.S. health insurer by membership and runs commercial, Medicare Advantage, and Medicaid plans. Denial volume is correspondingly high, but so is the reversal rate when appeals are filed correctly.

Patterns we see on UHC denials

Clinical criteria withheld in initial denial

UHC denials frequently cite 'not medically necessary' without disclosing the specific clinical criteria applied. Federal and state law require disclosure on request — and once disclosed, the criteria become the rebuttal map.

Specialty-drug formulary denials

Specialty injectables are often denied at the pharmacy benefit (Optum Rx) before they reach the medical benefit. Filing a formulary exception with manufacturer clinical data is the standard reversal path.

Medicare Advantage prior auth

UHC's Medicare Advantage plans have been the subject of multiple federal investigations into prior-auth denial rates. Internal appeals at level 1 reverse roughly 40%; level 2 (IRE/Maximus) is where escalation cases tend to land.

Appeal levels available

Internal level 1 (30 days for standard, 72h expedited), internal level 2 (in some states), then external/independent review. Medicare Advantage adds federal levels 2–5 (IRE → ALJ → Council → District Court).

Filing deadlines

Standard appeals must be filed within 180 days of the denial date. Urgent designations compress carrier response time to 72 hours. Medicare Advantage level-2 deadline is 60 days from level-1 denial.

How we file UHC appeals

We file all UHC appeals with the criteria-disclosure request embedded in the cover letter. This anchors the procedural record from day one.
