En español | You should probably enroll during the seven-month window known as your Initial Enrollment Period (IEP). It consists of the three months before your 65th birthday, the month of your birthday, and the three months after your birthday. If you miss this deadline, you may have to pay higher premiums for Medicare Part B, which covers doctor bills, outpatient fees and other medical expenses. However, if you are 65 or older and covered under a group health plan, either from your own or your spouse’s current employment, you may have a “special enrollment period” in which to sign up for Medicare Part B. If you meet the requirements, you may be able to delay enrollment without a penalty. Proof of coverage under the employer plan is required for enrollment.
