Medicare Supplement Insurance (Medigap)

Insurance Glossary

A private policy that pays cost sharing Original Medicare leaves behind, such as the Part A and Part B deductibles, coinsurance and hospital costs beyond what Medicare covers. Plans are standardized by letter, so the benefits of a given letter are the same from one insurer to the next and only price and service differ, with Massachusetts, Minnesota and Wisconsin standardizing their plans differently. It cannot be paired with a Medicare Advantage plan, and outside the initial open enrollment window insurers in most states may apply medical underwriting.
