## TRICARE in Oklahoma Oklahoma is part of the **TRICARE East Region**. Since Oklahoma is in the East, the regional contractor responsible for managing the provider network, claims, and customer service is **Humana Military**. Beneficiaries living near the state's western border should note that while they are in the East Region, neighboring states like Texas (west of I-35 in some areas) and New Mexico fall under the West Region, managed by TriWest Healthcare Alliance.
## Major military installations Oklahoma is home to several major installations across multiple branches, providing a robust network of military treatment facilities (MTFs) for Prime enrollees:
* **Tinker Air Force Base** – Air Force (Oklahoma City) * **Fort Sill** – Army (Lawton) * **Altus Air Force Base** – Air Force (Altus) * **Vance Air Force Base** – Air Force (Enid) * **McAlester Army Ammunition Plant** – Army (McAlester) * **Oklahoma National Guard** – Multiple locations (Headquartered in Oklahoma City)
## Plans available in Oklahoma Beneficiaries in Oklahoma can choose from several plans depending on their sponsor's status and their proximity to a military base:
| Plan | Best For | | :--- | :--- | | **TRICARE Prime** | Managed care with lowest out-of-pocket costs; primarily available in Prime Service Areas (PSAs) near bases like Tinker or Fort Sill. | | **TRICARE Select** | PPO-style plan offering the most flexibility to see any network or non-network provider without a referral. | | **TRICARE Reserve Select (TRS)** | Premium-based plan for qualified Selected Reserve members and their families. | | **TRICARE Retired Reserve (TRR)** | Premium-based plan for retired Reserve members under age 60. | | **TRICARE for Life (TFL)** | Wrap-around coverage for those with Medicare Part A and B. | | **TRICARE Young Adult** | Coverage for adult children (ages 21–26) who have aged out of regular TRICARE. |

## Finding care in Oklahoma To find a doctor, specialist, or urgent care center in Oklahoma, use the **Humana Military Provider Directory**.
* **Network vs. Non-Network:** In Oklahoma cities like Tulsa or Oklahoma City, you will find a large density of "Network" providers. Using network providers results in lower cost-shares. If you see a "Non-Network" provider, your out-of-pocket costs will be higher, and you may have to file your own claims. * **Military Treatment Facilities (MTFs):** If you are enrolled in TRICARE Prime at Fort Sill (Reynolds Army Health Clinic) or Tinker AFB (72nd Medical Group), your Primary Care Manager (PCM) will usually be a military provider. * **Telehealth:** Humana Military offers robust telehealth options for Oklahoma residents. Many behavioral health providers in Oklahoma offer virtual visits, which are covered at the same rate as office visits for most plans.
Common questions for Oklahoma beneficiaries
**I am PCSing to Fort Sill. When should I switch my enrollment?** You should not switch your enrollment until you have actually arrived in Oklahoma and have updated your address in DEERS. Once your new Oklahoma address is reflected in DEERS, contact Humana Military to transfer your coverage to the East Region.
**Can I use TRICARE and Oklahoma Medicaid (SoonerCare) together?** Yes. By law, TRICARE pays secondary to all other health insurance plans, except for Medicaid. If you are eligible for both, SoonerCare pays last.
**What if I live in a rural part of Oklahoma far from a base?** If you live more than 40 miles (or a 30-minute drive) from an MTF, you may not be eligible for TRICARE Prime unless you waive your drive-time standards. Most rural Oklahoma residents opt for **TRICARE Select**, which allows them to use local civilian doctors.
