Medicare uses a 5-level appeals ladder. Most beneficiaries don't know it exists past level 1. About 50% of appeals are won at level 1 (redetermination). Of those denied, another 60%+ are won at level 2 (reconsideration by independent QIC). Of THOSE denied, ~80% are won at level 3 (ALJ — Administrative Law Judge hearing).
Level 1 — Redetermination: 120 days to file. Plan reviews. ~60-day decision.
Level 2 — Reconsideration: 180 days from Level 1 denial. Independent contractor (QIC) reviews.
Level 3 — Administrative Law Judge (ALJ) hearing: 60 days from Level 2 denial. Requires minimum dollar amount in dispute ($190 in 2026). YOU show up, often with prescriber on phone.
Level 4 — Medicare Appeals Council: 60 days from Level 3 denial.
Level 5 — Federal District Court: 60 days from Level 4 denial. Requires significant dollar amount ($1,900 in 2026).
Most denials are reversed at Level 1 or 2 if the documentation is right. Many seniors give up at Level 1 because they didn't document properly. Don't.
