How to Appeal a Medicare Denial and Challenge a Decision

A Medicare denial isn’t always the final word: for Original Medicare, submit a written redetermination request within 120 days of receiving your Medicare Summary Notice, according to the Centers for Medicare & Medicaid Services. How to appeal a Medicare denial depends on your coverage: Medicare Advantage and Part D plans have their own appeal instructions, which they must provide in writing. In Palm Beach Gardens, Florida, start by checking the denial notice and following the instructions for your plan.

A denial can feel confusing, especially when you believe a service or prescription is still needed. This guide explains how to appeal a Medicare denial under Original Medicare and how the separate processes work for Medicare Advantage and Part D. You’ll learn what to include, how to respond, and when an expedited appeal may apply.

Appealing Medicare Advantage and other health plan decisions

First, identify whether the denial came from Original Medicare, Medicare Advantage, or a Part D drug plan. Then follow the appeal route and deadline stated in the notice.

1. Identify the Type of Medicare DecisionCheck whether the decision denies coverage or payment for a service, supply, item, or prescription drug. These are appealable decisions, including a plan’s decision to stop paying for care you believe is still needed. According to the Centers for Medicare & Medicaid Services, people with Original Medicare have 120 days after receiving a Medicare Summary Notice to request a redetermination. Use the appeal instructions on the notice.

2. Review Appeal Decision TimelinesSend the appeal to the organization that issued the denial, and state whether waiting could threaten your health. Standard private-plan service appeals generally receive decisions within 30 days; payment appeals, within 60 days. According to the Centers for Medicare & Medicaid Services, a Medicare Advantage plan must respond to an expedited appeal within 72 hours. For Part D, an approved expedited redetermination must be completed, with notice to you and the prescriber when appropriate, within 72 hours.

3. Check Redetermination Notification TimingTrack when the Original Medicare contractor receives your redetermination request and watch for its decision notice. A contractor usually decides within 60 days after receiving the request. If you disagree with that decision, according to the Centers for Medicare & Medicaid Services, you have 180 days after receiving the MAC decision letter or Medicare Summary Notice to request a level 2 reconsideration. Follow the next-level instructions in the notice.

4. Consider the Cost of AppealingYou can appeal an Original Medicare denial even if the claim amount is small. A redetermination has no minimum monetary threshold, so the amount at stake does not affect your right to request review. For Medicare Advantage or Part D, follow the plan’s written appeal instructions. State which coverage or payment decision you dispute, why you disagree, and include relevant information from your prescriber or provider.

How to appeal a denied Medicare claim

Use the decision notice to identify your appeal level and the next filing step. Original Medicare has five levels, including review by a federal district court.

1. Follow the Five Appeal LevelsStart with a redetermination, then request level 2 reconsideration if you disagree. The third level is an Administrative Law Judge hearing or review of dismissal, requested with form OMHA-100. Level 4 goes to the Medicare Appeals Council; level 5 may proceed to judicial review in federal district court. Each decision letter explains how to move forward, so keep the notice with your claim summary and appeal papers.If a hospital or facility says your care is ending, read the written fast-appeal notice before services stop. It explains how to request an expedited review when you believe Medicare-covered care is ending too soon. This may apply to hospital, skilled nursing facility, home health, rehabilitation, or hospice services.

2. Continue to Later Appeal LevelsFollow the deadline and submission directions in each decision letter. After a Qualified Independent Contractor decision, request level 3 review within 60 days. If the Administrative Law Judge decides against you, request Medicare Appeals Council review within 60 days after receiving that decision. A later appeal should address the reasons in the prior notice and include relevant records, such as a doctor’s explanation of the care service.Keep copies of every filing and decision. If a representative files for you, provide legal permission using form CMS-1696. This helps keep the appeal record organized as it moves through the levels. For a hospital fast appeal, act on the provider’s notice promptly, because it concerns care that is scheduled to end.

Medicare Advantage and Part D appeals

Use the plan’s written instructions to challenge a coverage decision. Medicare Advantage and Part D appeals follow plan-specific procedures, not Original Medicare’s contractor review route.

1. File a Medicare Advantage appeal promptly. According to the Centers for Medicare & Medicaid Services, file within 60 days of the date on the denial notice. Identify the denied health care service, explain why you disagree, and include relevant records, such as a doctor’s explanation of why treatment should continue. Follow the plan’s submission instructions.

2. Start a Part D appeal with the drug plan. If a prescription drug is denied, request a coverage determination or challenge an existing determination through the plan. Part D members have 65 days to initiate an appeal. Describe the medication and explain why the prescribed drug is needed. Include supporting information from the prescriber, especially when the denial concerns coverage or access restrictions.

3. Request an expedited review when urgency matters. Explain how waiting for a standard decision could affect your health care. A Medicare Advantage plan must respond to an expedited appeal within 72 hours. For Part D, an approved expedited redetermination must be completed within 72 hours, with notice sent to you and the prescriber when appropriate. A hospital or treatment schedule may make prompt action especially important.

4. Read the decision before moving forward. If the plan denies your written appeal, check its decision notice for the next appeal level and filing instructions. Keep the determination, supporting documents, and submission records together. If a representative handles the appeal, include the required appointment or authorization paperwork.
