Medicare Supplement (or Medigap) insurance plans are designed to assist with the costs that Medicare Parts A and B fail to pay and do not cover. Most states have 10 plans designated by the letter, and each one offering a basic level of benefits.
In the majority of states, Medigap plans offer the same benefits (under the same letter). For instance, the benefits of a Plan A in one state will be the same for all insurance companies, no matter where a person is. There’s no need to compare between the two like plans, as the only difference is the premium cost.
