United States citizens 65 years of age and older are eligible to receive Original Medicare (Parts A and B), which is administered by the federal government (through the Department of Health and Human Services' Centers for Medicare and Medicaid Services).
Those eligible for Original Medicare have the option of purchasing supplemental insurance coverage from a private insurance company (such as Humana, Aetna, and BCBS, three of the largest private providers in the United States.)
Blue Cross Blue Shield Medicare plans provide a broad range of Medicare Advantage, Medicare Part D, and supplemental policies. This article presents the spectrum of policies available.
