Application for Medicare Part A and Part B
Special Enrollment Period
(Exceptional Circumstances)
Use this form to sign up for Medicare Part A (Hospital Insurance) or Part B (Medical Insurance) during a Special Enrollment Period because of an exceptional situation.
Some common reasons for qualifying include being impacted by a natural emergency or disaster, losing Medicaid coverage, or being released from jail. You’ll need to provide written proof that you experienced circumstances outside of your control that prevented you from enrolling in Medicare during your Initial Enrollment Period or another valid enrollment period.
Learn more about Medicare enrollment periods (including Special Enrollment Periods) at Medicare.gov/basics/get-started-with-medicare/sign-up/when-does-medicare-coverage-start.
When is your Initial Enrollment Period?
Your Initial Enrollment Period is the first chance you have to sign up for Medicare Part B. It lasts for 7 months. It begins 3 months before the month you reach 65, and ends 3 months after the month you reach 65. If you have Medicare due to disability, your Initial Enrollment Period begins 3 months before the 25th month of getting Social Security Disability.
If you have a Health Savings Account (HSA), you must stop contributing 6 months before you apply for Medicare so you won’t be penalized by the IRS. Get more information about HSA penalties at IRS.gov.
If you sign up after your Initial Enrollment Period, you may have to pay a late enrollment penalty of 10% for each full 12-month period you don’t have Part B but were eligible to sign up.
