## Quick answer The 375th Medical Group at Scott Air Force Base (AFB) is a large military treatment facility (MTF) in Illinois providing primary and specialty care to over 60,000 beneficiaries. It serves as a central hub for TRICARE Prime enrollment in the East Region, offering clinics ranging from pediatrics to flight medicine, though it does not operate an Emergency Room or an inpatient hospital.

## In detail The 375th Medical Group (MDG) operates as a "super-clinic" rather than a traditional hospital. Located at Scott AFB, it supports the global mission of U.S. Transportation Command (USTRANSCOM) while providing outpatient services to active duty members, retirees, and their families.

### Accessing Care and Enrollment Scott AFB is located in the **TRICARE East Region**, managed by **Humana Military**. Beneficiaries living within a 30-mile radius (the Prime Service Area) are typically required to enroll in TRICARE Prime at the 375th MDG if space is available.

### Available Services The facility provides comprehensive outpatient care including: * **Family Practice & Internal Medicine:** Routine exams and chronic disease management. * **Pediatrics:** Care for dependents from birth through adolescence. * **Flight Medicine:** Specialized physicals and readiness care for aircrews. * **Ancillary Services:** Full-service pharmacy (Express Scripts integration), Radiology/Imaging, and Laboratory services. * **Mental Health:** Counseling and psychiatric services for active duty and dependents.

### No Emergency Services It is critical to note that the 375th MDG does **not** have an Emergency Room. For life-threatening emergencies, patients should call 911 or go to the nearest civilian hospital, such as St. Elizabeth’s in O'Fallon or Memorial Hospital in Belleville. For non-emergent after-hours care, TRICARE Prime members should call the Nurse Advice Line (NAL) at 1-800-TRICARE to avoid point-of-service charges.

### Pharmacy and Costs The Scott AFB Pharmacy is one of the busiest in the Air Force. * **MTF Pharmacy:** $0 copay for all formulary prescriptions (2026 rates). * **Home Delivery:** Express Scripts handles mail-order shifts for maintenance drugs. * **Network Pharmacy:** If you fill a script at a local CVS or Walgreens, expect to pay approximately $16 for generics or $43 for brand-name drugs (2026 rates for most plans).

## Who this applies to * **Active Duty Service Members (ADSMs):** Required to receive all primary care at the 375th MDG and require referrals for any civilian specialty care. * **Active Duty Family Members (ADFMs):** Can enroll in TRICARE Prime to receive $0-copay care at Scott AFB or choose TRICARE Select to see civilian providers with an annual deductible. * **Retirees and Families:** Eligible to enroll at Scott AFB if the facility has "capacity." If the 375th is at max capacity, retirees may be directed to civilian TRICARE network providers in the O'Fallon/Belleville area. * **TRICARE For Life (TFL) Beneficiaries:** May use the Scott AFB pharmacy at no cost but typically receive primary care from Medicare-participating providers off-base.

Common scenarios

**Scenario 1: Active Duty Pharmacy Use** Tech Sgt. Miller is stationed at Scott AFB. He receives a prescription for an allergy medication from the 375th MDG. He fills it at the base pharmacy. **Total Cost: $0.**

**Scenario 2: Retiree Urgent Care** A retired Navy Commander living in O'Fallon is enrolled in TRICARE Select. On a Saturday, he visits a civilian Urgent Care center because the 375th MDG is closed. Under 2026 TRICARE Select rates, he pays a negotiated network copay (typically around $35–$60 depending on his "Group" status).

**Scenario 3: Referral to Specialist** An ADFM enrolled in TRICARE Prime at Scott AFB needs to see a cardiologist. The 375th MDG Primary Care Manager (PCM) submits a referral to Humana Military. Once approved, the spouse sees a civilian specialist in St. Louis. **Total Cost: $0** (because it was an authorized Prime referral).
