CHAMPUS

The Civilian Health and Medical Program of the Uniformed Services (in the United States).

CHAMPUS is a federally-funded health program that provides beneficiaries with medical care supplemental to that available in military and Public Health Service (PHS) facilities.

All CHAMPUS beneficiaries move over to Medicare at age 65. CHAMPUS is like Medicare in that the government contracts with private parties to administer the program.

Recently revamped as a managed-care system and renamed TRICARE, but still widely known under its old moniker.
