Medicare plan complaint checklist

Use this checklist to prepare a grievance about a Medicare health or drug plan without losing a separate appeal deadline.

Keep complaints and appeals separate

A complaint addresses service, access, conduct, quality, or process. A coverage or payment denial usually requires an appeal. Complete both routes when the facts create both issues.

1. Classify the issue

  • Write the service, access, treatment, quality, communication, or process problem.
  • Identify any separate coverage or payment denial that requires an appeal.
  • Read every notice for a shorter or separate deadline.

2. Identify the responsible plan

  • Plan name and type: Medicare Advantage, other Medicare health plan, or Part D plan.
  • Member-services and grievance contact from the membership card or Evidence of Coverage.
  • Official Medicare Complaint Form when you choose the Medicare.gov route.

3. Record the incident

  • Date, time, location, and people involved.
  • What happened and how it affected access, service, care, or rights.
  • Names, reference numbers, and summaries of calls or messages.

4. Protect the deadline

  • Calculate the general 60-calendar-day filing period from the event or incident.
  • Do not wait for a related appeal to finish.
  • Keep proof showing when the grievance was submitted.

5. Gather supporting material

  • Plan notices, portal messages, letters, appointment records, or call logs.
  • Statements from a provider or witness when relevant.
  • Receipts or other records that document the problem.
  • Representative authorization if another person is filing.

6. State the requested resolution

  • Ask for a clear investigation and explanation.
  • Identify a practical correction, such as accessible communication, an appointment, corrected information, or staff follow-up.
  • Do not rely on a grievance alone to overturn a coverage denial.

7. Check the narrow 24-hour rule

  • For Medicare Advantage, determine whether the grievance concerns a plan extension or refusal to expedite an organization determination or reconsideration.
  • For Part D, determine whether it concerns refusal to expedite a coverage determination or redetermination before the drug was purchased or received.
  • Ask the plan to identify the applicable grievance timeframe in writing.

8. Track the response

  • Record the date the plan received the complaint.
  • Calendar the general 30-day response limit.
  • Save any written notice of an extension of up to 14 calendar days.
  • Contact 1-800-MEDICARE or SHIP if the grievance is not addressed.
