If you did not apply for Medicare Part B (medical insurance) within three months before or after turning age 65, you have another chance each year during the General Enrollment Period.
The period runs from January 1 to March 31 every year.
If you don’t enroll in Part B when you’re first eligible for it, you may have to pay a late enrollment penalty for as long as you have Part B coverage. Your monthly premium will increase 10% for each 12-month period that you were eligible for Part B but did not sign up for it.
Your coverage starts the first day of the month after you sign up. To learn more about Medicare, visit www. ssa.gov/benefits/medicare.
