Important: Plan F and Plan C are not available to beneficiaries who became eligible for Medicare on or after January 1, 2020.
You must be enrolled in Medicare Part B to be eligible for a Medigap plan. If you are enrolled in Medicare Advantage (Medicare Part C), you cannot enroll in a Medigap plan. You may have the option to drop your Medicare Advantage plan and join a Medigap plan instead, but you must first enroll in Original Medicare (Medicare Part A and Part B).
If you are younger than 65 and qualify for Medicare because of a disability or medical condition, your eligibility for Medigap will vary based on where you live. Some states require insurance companies to offer Medigap to Medicare recipients under the age of 65 and some do not.
Enrolling in a Plan
If you're considering adding a Medigap plan to your Original Medicare coverage, it is important to enroll during your open enrollment period. Your open enrollment period is the six-month period that begins the month you turn 65 and are enrolled in Medicare Part B.
If you enroll in Medigap during your open enrollment period, insurers cannot use medical underwriting to determine how much you'll pay for a policy.
If you enroll in Medigap outside of your open enrollment period, however, you could be denied coverage or be required to pay a higher monthly premium.
