Medicare Supplement insurance refers to plans sold by private insurance companies that fill in the gaps left uncovered by Original Medicare Part A and Part B. Medicare Supplement insurance is sometimes called Medigap. Those who purchase Medigap must be first enrolled in Medicare Part A and Part B. As a result, those who use Medigap need to pay a premium for Medicare Part B and a premium for Medigap.
Differences Between Medicare Supplement Insurance and Medicare Advantage
Medicare Advantage and Medicare Supplement Insurance are two very different plans. Medicare Supplement insurance is an additional plan that pays for many of the expenses that Medicare Part A and Part B do not cover. Medicare Advantage, on the other hand, is a policy that includes Medicare Part A and Part B and also extends that coverage.
