How to cancel Medicare by mail

  1. Note your account details

    You will need the policy number, the name on the policy and the date you want cover to end. Use exactly the details Medicare holds, so the request can be matched to your account.

  2. Write your request

    The letter asks Medicare to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Medicare”. Postbye fills it in from our English template.

  3. Mail it with tracking

    Take the letter to the post office and ask for certified delivery to 21244 Baltimore. Keep the tracking number it gives you.

  4. Save the tracking record

    File the receipt with the letter. A Medicare charge dated after delivery is the one to dispute, and these two documents are what you quote.

With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Medicare, check these

Notice period: Part B coverage ends at the end of the month after the request is filed (e.g. filed April 5, ends May 31). Work out your cancellation deadline.

  • Part B usually has to be dropped in writing with your signature, and you pay premiums for every month you have coverage
  • Re-enrolling in Part B may mean waiting for the General Enrollment Period (Jan 1 - Mar 31) and paying a monthly late penalty for as long as you have Part B
  • Part D drug coverage can be dropped only at set times: Open Enrollment (Oct 15 - Dec 7, effective Jan 1), the Medicare Advantage Open Enrollment Period, or certain other circumstances
  • Going 63+ days in a row without creditable drug coverage can mean waiting for an enrollment period and a Part D late penalty

Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancel Medicare

Cancelling a insurance or protection plan

Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.

A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.

Medicare lets you cancel directly (for Part B / premium Part A, a signed written request via Social Security (ssa.gov/agency/contact); for Part D drug plans, call 1-800-MEDICARE, mail or fax a signed notice to the plan, or online if the plan offers it). A letter is the fallback that leaves a dated record when the direct route fails.

Medicare cancellation questions

Where do I send my Medicare cancellation letter?

Address the letter to Medicare, 750 Security Blvd, Baltimore, MD 21244.

How long does a cancellation letter to Medicare take?

Medicare's address is in Maryland. USPS states that First-Class Mail is delivered in 1 to 5 days. The delivery receipt records the day your letter actually arrived, and that is the date to quote. USPS: First-Class Mail

Does Medicare require notice before I cancel?

The rule we recorded for Medicare: Part B coverage ends at the end of the month after the request is filed (e.g. filed April 5, ends May 31). Mail the letter early enough that its delivery receipt falls inside that window.

What do I need to cancel Medicare?

Have the policy number, the name on the policy and the date you want cover to end to hand. The details in the letter need to match what Medicare has on file.

Will Medicare confirm my cancellation?

The letter asks Medicare to end the account, stop further charges and confirm in writing, but a reply is not guaranteed. What you can rely on is the delivery receipt: it shows the date Medicare received the request. If a charge posts after that date, quote the receipt with your copy of the letter.
