Medicare terms

Learn more about Medicare. Start with these definitions.



Enrollees in a Medicare health plan may file a grievance if they are unsatisfied with their treatment by those who administer their health plan. Conversely, an enrollee would file an appeal to complain about a treatment decision or service that is denied coverage.

guaranteed issue rights

Guaranteed issue rights – also known as “Medigap protections” – require insurance carriers by law to offer you a Medigap policy, prohibiting it from denying you coverage or charging you more for coverage based on reasons that include pre-existing conditions.

guaranteed renewable

Guaranteed renewable refers to a health plan in which the insurer is required to renew the policy if the policy holder has been consistently paid the policy premiums.

Medigap plans are guaranteed renewable. Medicare Advantage and Medicare Part D plans are also guaranteed renewable, but benefits on those plans can change significantly from one year to the next, so although your plan will renew if you don’t make changes during open enrollment (and assuming you continue to pay your premiums), your coverage might be very different in the coming year.
