Did my Medicare part B start this month?

A) To determine if your Medicare Part B started this month, you’ll need to check your Medicare card or your enrollment confirmation letter.

These documents will clearly indicate your Part B start date.

If you don’t have these documents, here are some other options:
Check Your Social Security Statement: If you receive Social Security benefits, your statement might indicate your Medicare enrollment and start date.
Contact the Social Security Administration: You can call the Social Security Administration at 1-800-772-1213 to verify your Medicare enrollment and start date.
Contact Your Medicare Advantage Plan (if applicable): If you’re enrolled in a Medicare Advantage plan, you can contact their customer service to verify your Part B start date.
Remember: The start date for Medicare Part B can vary depending on when you enrolled. Generally, it starts the first day of the month after you enroll, but there are exceptions.
