UHC-Specific Best Practices
- Reference the UHC Medical Policy Bulletin by number. UHC publishes these at uhcprovider.com. Citing the exact policy and showing you meet the criteria carries more weight than generic clinical arguments.
- Specify your plan type. UHC administers fully insured plans, self-funded employer plans, and Medicare Advantage plans. Each has different appeal rules. Always identify which type you have.
- Use the correct appeals address. UHC has multiple appeals processing centers. The correct address is on your denial letter. Using the wrong address delays processing.
- Note the reviewer's qualifications. If the denial was made by a non-specialist, note this in your appeal and request review by a board-certified specialist in the relevant field.
- Request the Milliman criteria. UHC uses Milliman Care Guidelines for many medical necessity determinations. You have the right to know which specific criteria were applied.
Delivery Tip
Send your UHC appeal via certified mail with return receipt, or by fax with a confirmed transmission receipt. UHC processes millions of documents annually, and appeals have been reported lost. Keep copies of everything, including proof of delivery with date stamps.
