The eastern U.S. TRICARE region, administered by Humana Military — covers most of the eastern half of the country plus parts of a few border states.

Applies to: All TRICARE plans · East

The TRICARE East Region covers Alabama, Connecticut, Delaware, DC, Florida, Georgia, Kentucky, Maine, Maryland, Massachusetts, Michigan, Mississippi, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, and West Virginia — administered by Humana Military (800-444-5445).

Arkansas, Indiana, Missouri, and Wisconsin are split by ZIP code between East and West, so two families in the same state — even neighboring towns — can fall under different regional contractors with different rules and networks. Always confirm your specific region by ZIP code rather than assuming based on your state.
