Medicare Advantage Denial Appeals
Medicare Advantage Denial Appeals: Overview
Medicare Advantage appeals follow a three-tier CMS process: (1) MA plan redetermination (7 days standard, 72 hours expedited), (2) Independent Review Organization (IRO) review if plan denies, (3) Administrative Law Judge (ALJ) review for claims exceeding $200. Understand timelines, requirements, and evidence standards at each stage.
Key Requirements
- File Within 60 Days: Submit redetermination request within 60 calendar days of the denial date. Missing this deadline generally forfeits appeal rights.
- Include Clinical Evidence: Attach medical records, test results, specialist recommendations, and clinical notes that address the specific denial reason.
- Reference Denial Code: Include the original CARC code and denial reason in your appeal submission for clarity.
- Request Expedited Review if Urgent: For cases where a 7-day delay poses risk to patient health, request 72-hour expedited review with clinical justification.
- Document All Submissions: Keep copies of all appeal correspondence, denials, and supporting documentation for IRO escalation if needed.

Level 1: MA Plan Redetermination . Submit within 60 days. Plan responds in 7 days (standard) or 72 hours (expedited).
