If you are eligible for Medicare, but not currently receiving Social Security retirement benefits or railroad retirement benefits, there are three different time periods during which you can enroll in Medicare Parts A and B.

You can enroll in Medicare at anytime during this seven-month period, which includes the three months before, the month of, and the three months following your 65th birthday.
- If you enroll during the first three months of your IEP, coverage begins the month in which you first become eligible for Medicare.
- If you enroll during the fourth month of your IEP, coverage begins the month following the month of enrollment.
- If you enroll during the fifth month of your IEP, coverage begins the second month following the month of enrollment.
- If you enroll during the sixth or seventh month of your IEP, coverage begins the third month following the month of enrollment.
- General Enrollment Period (GEP). If you do not enroll in Medicare or if you refused Medicare when you originally became eligible for it, you can sign up during the GEP, which is from January 1st through March 31st of every year. Your coverage will begin July 1st of the year you sign up. You will have to pay a Part B premium penalty for every year you delayed enrolling in Medicare Part B.
- Special Enrollment Period (SEP). You can delay enrollment in Part B without penalty if you were covered by employer health insurance through your or your spouse’s current job when you first become eligible for Medicare. You can enroll in Medicare without penalty at any time while you have group health coverage and for eight months after you lose your group health coverage or you (or your spouse) stop working, whichever comes first.
The date when your Medicare coverage begins depends on when you signed up.
