Final answer:
Groups not covered by TRICARE or CHAMPVA include civilian adults without military connections, individuals over 65 who are served by Medicare, the general public without military status, and wealthy individuals who do not qualify based on income or special status.
Step-by-step explanation:
Groups that are not covered by TRICARE or CHAMPVA are typically those that do not fall under the categories of military personnel, veterans, or their immediate families. TRICARE is a health care program for uniformed service members, retirees, and their families. CHAMPVA (the Civilian Health and Medical Program of the Department of Veterans Affairs) is for eligible beneficiaries which include the spouse or widow(er) and children of a veteran who is rated permanently and totally disabled due to a service-connected disability, was disabled at the time of death, or died of a service-connected disability. Therefore, groups such as civilian adults without military connections or those above 65 who are covered by Medicare, which provides health insurance to all those over age 65, are not covered by TRICARE or CHAMPVA. This also includes the non-military general public and wealthy individuals who do not qualify based on income or special status.
