Medicare Advantage (Part C)
Medicare Advantage plans are private Part C plans that replace Original Medicare. They have the strongest appeal-rights framework in US health insurance: 5 levels of appeal, expedited 72-hour decisions, and binding Independent Review Entity review.
What this plan type is
Medicare Advantage (Part C) is the private-plan alternative to Original Medicare (Parts A + B). Beneficiaries enroll with a private carrier (UnitedHealthcare, Humana, Aetna, Anthem, Kaiser, etc.) that contracts with CMS to provide all Original Medicare benefits — often with extra benefits like vision, dental, OTC allowance, transportation. ~52% of Medicare beneficiaries are on MA plans (2024). Many MA plans are MAPD plans bundling Part D prescription drug coverage.
Your appeal rights
Five-level appeal track per 42 CFR Part 422 Subpart M: (1) Plan reconsideration, (2) Independent Review Entity reconsideration (Maximus Federal Services), (3) ALJ hearing at OMHA (low $180 threshold), (4) Medicare Appeals Council, (5) federal court. Standard reconsideration: 30 days pre-service / 60 days post-service. Expedited reconsideration: 72 hours when life/health would be jeopardised. CRITICAL: if the plan misses any deadline, the case is auto-forwarded to the IRE.
Common denial patterns
- Service not covered under the plan's reduced network (CARC 256)
- Prior auth absent or denied
- Out-of-network non-emergency
- Step therapy under MA Part B drug rules

What's unique about this plan type
