Blue Cross Blue Shield (BCBS) offers Medicare Supplement Insurance in several states, including Illinois and Texas; individuals who are interested in this insurance should be sure to conduct research on these policies for their individual state as the available options for Medicare Supplement Insurance may vary from state to state. There are many rules regarding Medicare Supplement Insurance that apply to policies purchased in any state from any company, as reported by the U.S. Centers for Medicare and Medicaid Services. Private companies, such as BCBS, may sell insurance policies to Medicare recipients in order to cover some of the gaps in coverage for things that Medicare does not cover.
Because Medicare Supplement Insurance covers these "gaps," it is sometimes known as Medigap coverage, as noted by the U.S. Centers for Medicare and Medicaid Services. In order to sign up for one of these policies, individuals need to have Medicare Part A and Part B insurance; this is true of BCBS Medicare Supplement Insurance and all other private sector insurers. Individuals who hold these policies must pay a monthly premium to BCBS in addition to any premiums they pay to the government for their Medicare Part B coverage. BCBS offers a variety of different types of Medigap coverage, including high-deductible plans and emergency coverage during foreign travel.
