A Medigap policy is a health insurance policy sold by private insurance companies to fill "gaps" in Original Medicare Plan coverage. Medigap policies must follow federal and state Laws. These laws protect you.
The front of the Medigap policy must clearly identify it as "Medicare Supplement Insurance."Each policy has a different set of benefits. Two of the standardized policies may have a high deductible option. In addition, any standardized policy may be sold as a "Medicare SELECT" policy.
Medicare SELECT policies usually cost less because you must use specific hospitals and, in some cases, specific doctors to get full insurance benefits from the policy. In an emergency, you may use any doctor or hospital.
