A “Group Health Plan” (GHP) is health insurance offered by an employer, union or association to its members while they are still working.  GHP coverage is based on current employment.  Employers with 20 or more employees are required by law to offer current workers and their spouses who are age 65 (or older) the same GHP health benefits that are provided to younger employees.

Examples of health insurance policies that are GHPs based on current employment.

If your GHP is based on current employment, you may not need Medicare Part B when you turn 65.  You may get a “Special Enrollment Period” (SEP) to sign up for Part B later without a penalty after the employment or group health plan coverage ends.  If you qualify, you can sign up for Part B anytime while you’re covered by an employer or union group health plan (GHP) based on current employment, or you can enroll in Medicare Part B anytime within 8 months after the employment ends or the GHP coverage ends (whichever happens first).
