A) According to the Medicare Website: When you’re first eligible for Medicare, you have a 7-month Initial Enrollment Period to sign up for Part A and/or Part B.
For example, if you’re eligible when you turn 65, you can sign up during the 7-month period that begins 3 months before the month you turn 65, includes the month you turn 65, and ends 3 months after the month you turn 65.
If you didn’t sign up for Part A and/or Part B (for which you must pay premiums) when you were first eligible, and you aren’t eligible for a Special Enrollment Period (see below), you can sign up during the General Enrollment Period between January 1–March 31 each year.
Your coverage will start July 1. You may have to pay a higher premium for late enrollment in Part A and/or a higher premium for late enrollment in Part B.
