How to appeal a UnitedHealthcare neurology — alzheimer's, parkinson's, als, epilepsy denial

The framework that applies to your appeal

Federal law gives you the right to a full and fair internal appeal, then an external review by an independent third party.

UnitedHealthcare-specific note: UHC's parent UnitedHealth Group owns Optum (PBM Optum Rx) and Surest. Surest plans have different cost-sharing rules. State complaints flow to state insurance department + DOL/EBSA for self-funded.

How to submit the appeal to UnitedHealthcare

1. Read the denial letter — note the exact denial reason code and the appeal deadline (180 days from the date on the letter).
2. Gather supporting documentation: physician letter of medical necessity, relevant clinical notes, peer-reviewed citations supporting the treatment for your indication, and the policy or coverage document UnitedHealthcare cited in the denial.
3. File the appeal through UnitedHealthcare's portal (members: https://www.myuhc.com ; providers: https://www.uhcprovider.com). Standard decision returns within 30 days; expedited urgent appeals return within 72 hours.
4. If denied again, request external review by an independent reviewer within 4 months of the final internal denial. In MN, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
