Which Army regulation covers CHAMPUS?

The regulation that covers CHAMPUS, which refers to the Civilian Health and Medical Program of the Uniformed Services, is indeed AR 40-121. This regulation is critical because it outlines the policies and procedures related to the program, ensuring service members and their dependents understand their health care benefits.

CHAMPUS provides civilian health care coverage for active duty members and their family members when military medical facilities are not available. Understanding this regulation helps personnel access necessary health services, navigate eligibility requirements, and file claims appropriately.

The other regulations mentioned focus on different aspects of Army health policies and are not specifically related to CHAMPUS. Each regulation serves its purpose in the military health system; however, AR 40-121 is the specific authority for CHAMPUS coverage and benefits.
