A Medicare Supplement or Medigap policy is a health insurance plan offered by private insurance companies to help cover the cost that Medicare doesn’t. Original Medicare has some expenses, such as co-insurance, co-pays and coverage gaps that the Medicare Supplements will pay for.
10 different types of Medicare supplements
In 1990 the federal government standardized Medicare when it created the outlines for each plan. Each plan is identified by a specific letter, such as Plan A, B, C, D (not to be confused with Parts A, B, C and D), F, G, K, L, M and Plan N. There is no difference in the set of benefits for a specific letter plan except monthly premiums. The insurance companies that offer Medicare Supplement plans have to offer the exact policies that Medicare Standardized in 1990.
The most popular plans today are Plan G, F, and N.
