What if I don't want Part B?
If your Medicare hasn’t started yet, there are 2 ways to drop Part B:
- If you were automatically enrolled in both Part A and Part B and sent a Medicare card, follow the instructions that come with the card, and send the card back. If you keep the card, you keep Part B and will pay Part B premiums.
- If you signed up for Medicare through Social Security, contact Social Security.
You must pay your Part B premium every month for as long as you have Part B (even if you don’t use it).
If your Medicare has started and you want to drop Part B, contact Social Security for instructions on how to submit a signed request. Your coverage will end the first day of the month after Social Security gets your request.
If you drop Part B, you generally won’t be able to enroll in Part B again until the next General Enrollment Period (January 1 – March 31st) and you may have to pay a late enrollment penalty.
