Common questions for Indiana beneficiaries

**What happens if I move from Indiana (East Region) to Illinois (West Region)?** Moving across the state line often involves a region change. Since Illinois is in the West Region (managed by TriWest Healthcare Alliance), you must update your address in DEERS and contact TriWest to transfer your enrollment. Your coverage does not move automatically.

**Does Indiana Medicaid work with TRICARE?** Yes. TRICARE is always the primary payer to Medicaid. If you are eligible for both, TRICARE pays first, and Indiana Medicaid acts as the payer of last resort.

**Can I get care at the Grissom ARB clinic?** The clinic at Grissom ARB is primarily focused on medical readiness for the 434th Air Refueling Wing. Routine care for family members and TRICARE Select retirees is generally handled by civilian providers in the local community. Always call the facility first to check current capability for "space-available" care.
