How to Appeal a Denied Medicare Claim (Updated for 2025)

A denied Medicare claim can be overwhelming, but understanding the reason behind the denial and knowing how to navigate the appeals process can make all the difference. Whether you're facing issues with medical necessity determinations, documentation errors, or coding mistakes, this comprehensive guide will walk you through each step of the Medicare appeals process, helping you secure the coverage you deserve.

Understanding Why Your Medicare Claim Was Denied

Before initiating an appeal, it's crucial to understand exactly why Medicare denied your claim. Common reasons for Medicare denials include:

• Medical Necessity Issues: Medicare determined the treatment wasn't medically necessary
• Documentation Errors: Missing, incomplete, or incorrectly filed paperwork
• Coding Mistakes: Errors in billing codes that led to claim rejection
• Coverage Limitations: The service isn't covered under your Medicare plan
• Maximum Benefit Reached: You've exceeded the allowed days in a hospital or care facility
• Network Restrictions: For Medicare Advantage plans, using out-of-network providers

Review your Medicare Summary Notice (MSN) or Explanation of Benefits (EOB) carefully, as it will contain the specific reason for denial and instructions for appealing.

Organizing these documents can help you create a strong appeal. The more complete and detailed your paperwork, the higher your chances of approval. A patient advocate can help.

The Five Levels of Medicare Appeals: Overview

The Medicare appeals process consists of five distinct levels, each offering an opportunity to have your case reconsidered by different authorities:

1. Redetermination by a Medicare Administrative Contractor (MAC)
2. Reconsideration by a Qualified Independent Contractor (QIC)
3. Hearing before an Administrative Law Judge (ALJ)
4. Review by the Medicare Appeals Council
5. Judicial Review in Federal District Court

You must complete each level before proceeding to the next, and each level has specific deadlines and documentation requirements.

Level 1: Filing a Medicare Redetermination Request

The redetermination is your first formal step in the appeals process. Here's how to navigate it successfully:

Documents to Collect Before Filing

• Your Medicare Summary Notice (MSN) or denial letter
• A doctor's statement explaining why the service was medically necessary
• Relevant medical records supporting your claim
• Any billing statements related to the denied service

How to File Your Redetermination Request

You have 120 days from receiving your Medicare Summary Notice to file a redetermination request. You can request a redetermination in two ways:

1. Complete Form CMS-20027 (Medicare Redetermination Request Form)
   • Download the form from the CMS website
   • Fill it out completely, including your Medicare number
   • Attach all supporting documentation
2. Submit a written request containing:
   • Your name, address, and Medicare number
   • The specific services or items you're appealing
   • The dates of service in question
   • A clear explanation of why you disagree with the denial
   • Your signature

Send your request to the address listed on your Medicare Summary Notice. Make sure to send it via certified mail with return receipt requested to confirm delivery.

What to Expect After Filing

The Medicare Administrative Contractor will review your appeal and typically issue a decision within 60 days. You'll receive a Medicare Redetermination Notice (MRN) explaining the decision. If your appeal is approved, Medicare will process the payment. If denied, the notice will include instructions for proceeding to Level 2.

Level 2: Requesting a Reconsideration

If your redetermination is denied, you can proceed to the reconsideration level, where an independent contractor reviews your case.

Filing a Reconsideration Request

You have 180 days from receiving the redetermination decision to request a reconsideration. To file:

1. Complete Form CMS-20033 (Medicare Reconsideration Request Form)
2. Include a copy of your redetermination notice
3. Submit any additional evidence not previously considered
4. Provide a clear explanation of why you disagree with the redetermination decision

Important: Evidence not submitted at the reconsideration level may be excluded from consideration at subsequent appeal levels unless you can demonstrate good cause for the late submission.

The Qualified Independent Contractor (QIC) will issue a decision within 60 days. If the decision isn't in your favor, you'll receive instructions for proceeding to Level 3.

Level 3: Administrative Law Judge (ALJ) Hearing

For the third level of appeal, you can request a hearing before an Administrative Law Judge if the amount in controversy meets the minimum threshold ($190 for 2025).

Requesting an ALJ Hearing

You must file within 60 days of receiving the reconsideration decision. You can request a hearing by:

1. Completing Form OMHA-100 (Request for Medicare Hearing by an ALJ)
2. Submitting a written request that includes:
   • Your name, address, and Medicare number
   • The appeal number assigned by the QIC
   • The dates of service for the items you're appealing
   • An explanation of why you disagree with the reconsideration decision

Hearings are typically conducted via telephone or video conference, though you can request an in-person hearing with good cause. You can also request a decision without a hearing (on-the-record review).

The ALJ will generally issue a decision within 90 days, though delays may occur due to high volumes of appeals.

Level 4: Medicare Appeals Council Review

If you're dissatisfied with the ALJ's decision, you can request a review by the Medicare Appeals Council.

Filing for an Appeals Council Review

You have 60 days from receiving the ALJ's decision to request an Appeals Council review. File by:

1. Completing Form DAB-101 (Request for Review of ALJ Medicare Decision/Dismissal)
2. Submitting a written request explaining which parts of the ALJ decision you disagree with and why

The Appeals Council generally issues a decision within 90 days. If the Council doesn't issue a timely decision, you may request escalation to the fifth level.

Level 5: Judicial Review in Federal District Court

The final level of appeal is judicial review in Federal District Court. To qualify, the amount in controversy must meet the minimum threshold ($1,840 for 2025).

You have 60 days from receiving the Appeals Council decision to file for judicial review. Follow the directions provided in the Appeals Council's decision letter.

Special Appeal Situations

Expedited Appeals

• When home health services are being terminated
• For skilled nursing facility discharge decisions

For expedited appeals, contact your Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO).

Part D Prescription Drug Appeals

If your Medicare Part D plan denies coverage for a medication, the appeals process is slightly different:

1. Request a coverage determination from your plan
2. If denied, request a redetermination within 60 days
3. If still denied, request reconsideration by the Independent Review Entity (IRE)
4. Follow with ALJ hearing, Appeals Council, and judicial review if necessary
