## TRICARE in Indiana Indiana is situated entirely within the **TRICARE East Region**. Under the current T-5 contract, **Humana Military** serves as the regional contractor responsible for managing the provider network, processing claims, and assisting with authorizations for Indiana beneficiaries. Because Indiana lacks a large active-duty "Mega-Base," many residents utilize a mix of network civilian providers and military clinics at Reserve and National Guard installations.
## Major military installations While Indiana does not host a massive active-duty Army or Navy installation, it is home to several critical Air Reserve and National Guard hubs:
* **Grissom Air Reserve Base** (Air Force Reserve) – Kokomo/Peru area. * **Camp Atterbury** (Army National Guard) – Edinburgh. * **Muscatatuck Urban Training Center** (Army National Guard) – Butlerville. * **Naval Surface Warfare Center (NSWC) Crane Division** (Navy) – Crane. * **122nd Fighter Wing** (Air National Guard) – Fort Wayne. * **181st Intelligence Wing** (Air National Guard) – Terre Haute.
## Plans available in Indiana Indiana residents have access to several TRICARE dental and health plan options depending on their military status (Active Duty, Guard/Reserve, or Retiree).

## Finding care in Indiana To find a doctor in Indiana, you must use the **Humana Military East Region Provider Directory**.
* **Network vs. Non-Network:** In cities like Indianapolis, Fort Wayne, and Evansville, there is a robust network of TRICARE-authorized providers. Using a "Network" provider keeps your out-of-pocket costs lower. If you use a non-network provider, you may face higher deductibles and cost-shares (2026 rates vary by plan—refer to the TRICARE.mil cost tool). * **Military Treatment Facilities (MTFs):** Many Indiana beneficiaries receive primary care through civilian providers, but those near Grissom ARB or Crane may have limited access to on-base clinics. * **Telehealth:** Indiana allows for broad telehealth services. Humana Military partners with Doctor On Demand for urgent care and mental health visits that do not require a referral for TRICARE Select patients.
Common questions for Indiana beneficiaries
**What happens if I move from Indiana to a West Region state?** Since Indiana is in the East (Humana Military), moving to a West Region state (like Illinois or Iowa) means switching your contractor to **TriWest Healthcare Alliance**. You must update your address in DEERS and contact TriWest to transfer your enrollment to avoid a coverage gap.
**How does TRICARE work with Indiana Medicaid?** TRICARE is always the primary payer to Medicaid. If you are a low-income veteran or family member in Indiana receiving Medicaid (Healthy Indiana Plan), TRICARE must pay its share of the claim first before Medicaid covers the remaining balance.
**Are there specialized military clinics in Indianapolis?** While there is no major active-duty hospital in Indianapolis, the **Richard L. Roudebush VA Medical Center** serves veterans. However, most TRICARE Prime and Select dependents in the Indy metro area utilize the civilian network, including systems like IU Health and Community Health Network.
