CMS-20027 Medicare redetermination guide

• CMS-20027 is used for a redetermination, which is the first level of the Medicare appeals process.
• You do not need to hand-fill the PDF. PostalForm can generate the completed form from an online workflow.
• Medicare generally says you have 120 days from the date you receive the Medicare Summary Notice to request a redetermination.
• You can include additional records or explanations that support the appeal.
• The completed form is mailed to the Medicare contractor identified on your notice, not to a generic CMS address.

Use CMS-20027 when:

• Medicare denied payment for a claim and you want first-level review.
• You disagree with an amount Medicare approved or refused to approve.
• You want to submit a written explanation and supporting evidence with the appeal.

If a provider or supplier is pursuing the appeal on your behalf for a specific item or service, you may also need a transfer-of-rights form. See the related section below for CMS-20031.

If you already know CMS-20027 is the right form, the fastest path is usually:

1. Answer the appeal questions in PostalForm's online version.
2. Let PostalForm generate the completed CMS-20027 PDF.
3. Review the form and supporting packet for accuracy.
4. Submit it for printing and mailing to the contractor listed on your notice.

That removes the usual download-edit-save-print cycle and keeps the form and mailing steps together.

Prepare these details first:

• Beneficiary name and Medicare number
• Medicare Summary Notice or initial determination notice
• The item or service you are appealing
• Date of service and claim details
• A concise explanation of why you disagree
• Any bills, medical records, notices, or correspondence that support the appeal

Keep the packet focused on the disputed item or service so the reviewer does not have to guess what should be reconsidered.

1. Enter the beneficiary details exactly as shown on the Medicare notice in the online workflow.
2. Identify the specific item or service you are appealing.
3. Explain why you disagree with the determination in plain, factual language.
4. Review the generated PDF and attach supporting documents in the same order you reference them.
5. Sign and date the form before mailing.

If you need to attach a longer explanation, keep the first page of the packet simple: form first, explanation second, evidence after that.

Mail CMS-20027 to the Medicare Administrative Contractor shown on the Medicare Summary Notice or initial determination letter for the claim you are appealing.

Do not rely on an old mailing address from a different claim packet. The address can vary by contractor and claim context.

CMS-20031 is different. It transfers appeal rights for one listed item or service to the provider or supplier that furnished it. Use that form when the provider or supplier will continue the appeal on your behalf for that specific claim item.

If you are appealing directly as the beneficiary, CMS-20027 is usually the main form to start with.

• Missing the appeal deadline shown in Medicare guidance
• Leaving the disputed item or service too vague
• Mailing to the wrong contractor address
• Sending a long packet with no explanation of why the denial was wrong
• Forgetting to sign and date the appeal request

• CMS-20027 form page
• CMS-20027 PDF
• Medicare: how do I file an appeal?
