When is the special enrollment period for Medicare Part B ?

When you first become eligible for hospital insurance (Part A), you have a seven-month period (your initial enrollment period) in which to sign up for medical insurance (Part B). A delay on your part will cause a delay in coverage and result in higher premiums. If you are eligible at age 65, your initial enrollment period begins three months before your 65th birthday, includes the month you turn age 65 and ends three months after that birthday. If you are eligible for Medicare based on disability or permanent kidney failure, your initial enrollment period depends on the date your disability or treatment began. If you accept the automatic enrollment in Medicare Part B, or if you enroll in Medicare Part B during the first three months of your initial enrollment period, your medical insurance protection will start with the month you are first eligible. If you enroll during the last four months, your protection will start from one to three months after you enroll. If you do not enroll in Medicare Part B during your initial enrollment period, you have another chance each year to sign up during a “general enrollment period” from January 1 through March 31. Your coverage begins on July 1 of the year you enroll. However, your monthly premium increases 10 percent for each 12-month period you were eligible for, but did not enroll in, Medicare Part B.
