What this is
This guide describes how to challenge Medicare coverage decisions—whether the patient has Original Medicare, a Medicare Advantage plan, or Part D drug coverage. Medicare uses federal appeal levels, not state insurance external review.
The Appeals Roadmap on the Insurance topic explains general advocacy habits (documents, deadlines, letters). This guide is the Medicare-specific ladder.
Appeal vs grievance
An appeal asks Medicare or the plan to change a coverage or payment decision for a specific service or drug. A grievance complains about quality of care, customer service, or how the plan treated the member. You can file both; keep separate reference numbers.
Medicare appeal levels (overview)
- Redetermination—appeal to the plan (Advantage or Part D) or Medicare contractor (Original Medicare). Deadlines are on the notice—often 60 days for standard service appeals; confirm each letter.
- Reconsideration—if unfavorable, appeal to the Qualified Independent Contractor (QIC) level with required forms.
- Administrative Law Judge (ALJ)—if amount in controversy and other requirements are met.
- Medicare Appeals Council—review of ALJ decisions.
- Federal court—rare without attorney support.

Expedited reviews
When normal timing could seriously harm health, request an expedited(fast) determination or appeal. Document clinical urgency in writing. Medicare Advantage and Part D have specific expedited rules—cite the patient's condition and why waiting is dangerous.
Part D drug appeals
Part D uses the same broad ladder but different forms and sometimes shorter deadlines for certain coverage determinations. A denied exception or formulary drug should trigger the notice's Part D appeal language—do not reuse commercial insurance appeal templates alone.

Bottom line
Medicare appeals are federal, staged, and deadline-driven. Read each notice, use Medicare forms, escalate through redetermination and reconsideration, and get SHIP help early when the case is complex.
