What is CMS-1763?
Form CMS-1763, Request for Termination of Premium Hospital Insurance of Supplementary Medical Insurance, is the CMS form on which an enrollee asks to end Medicare Part A (when a premium is paid for it), Part B or Part B Immunosuppressive Drug Coverage (Part B-ID).
The current PDF prints a longer title: Request for Termination of Medicare Premium Part A, Part B, or Part B Immunosuppressive Drug Coverage (Part B-ID). It carries OMB No. 0938-0025, which the form shows as expiring 08/31/2027, and the revision mark CMS-1763 (01/26).
The form collects the enrollee's name, Medicare Number, mailing address, phone number and email address. You then mark which coverage you want to end, enter the month and year it should end, and may give your reasons, which are optional. The enrollee signs and dates it.
The form states two rules. You can terminate Part A only if you pay a premium for it, while Part B or Part B-ID can be terminated at any time. Ending Part B also terminates Part A if you pay a premium for Part A. The form notes that Sections 1838(b) and 1818A(c)(2)(B) of the Social Security Act require a notice to the Social Security Administration (SSA) when termination is requested.
Who needs to file CMS-1763?
Medicare enrollees who want to end their coverage use Form CMS-1763. The form sets conditions for each type of coverage:
- Part A (Hospital Insurance): you can terminate it only if you pay a premium for it.
- Part B (Medical Insurance): you can terminate it at any time. If you pay a premium for Part A, ending Part B also ends Part A, and you confirm that you understand this by checking the statement printed on the form.
- Part B-ID (Part B Immunosuppressive Drug Coverage): you can terminate it at any time.
The form has a line for the name of the person completing it if that person is not the enrollee, so someone other than the enrollee may fill it in. The form does not describe who is allowed to sign for an enrollee.
If the form is signed with a mark (X), a witness who knows the person applying must also sign it, with the witness's name and the date.
When to file CMS-1763
Submit Form CMS-1763 when you decide to end your Part A (premium), Part B or Part B-ID coverage. The form sets no deadline of its own: Part B and Part B-ID can be terminated at any time, and Part A only if you pay a premium for it.
The date you submit decides when coverage ends:
- Part A and Part B: coverage ends on the last day of the month after the month you submit the request. If you submit it April 5, coverage ends May 31.
- Part B-ID: coverage ends on the last day of the month you request. If you ask for coverage to end in April, your last day of coverage is April 30.
If you change your mind, the form says you must contact SSA before your coverage end date.

- By mail: send the completed, signed form to your local Social Security office.
- By fax: fax the completed, signed form to your local Social Security office.
- Finding the office: the form directs you to SSA.gov/locator to find an office near you.

Common mistakes to avoid
- Requesting to end Part A when you do not pay a premium for it; the form allows Part A termination only if you pay a premium.
- Ending Part B without realizing it also terminates Part A if you pay a premium for Part A.
- Expecting Part A or Part B coverage to end in the month you submit; it ends the last day of the month after you submit.
- Entering the wrong end month for Part B-ID, which ends the last day of the month you request.
- Leaving the form unsigned or without the date signed in mm/dd/yyyy format.
- Signing with a mark (X) and not adding the name, signature and date of a witness who knows the person applying.
- Waiting until after the coverage end date to change your mind; you must contact SSA before that date.
- Sending the form to CMS instead of mailing or faxing it to your local Social Security office.
