## Quick answer TRICARE covers the diagnosis and treatment of both Type 1 and Type 2 diabetes as a medical necessity. This includes coverage for insulin, oral medications, blood glucose monitors, and advanced technology like Continuous Glucose Monitors (CGMs) and insulin pumps, though specific authorization and pharmacy rules apply depending on your plan and the device type.

## In detail Managing diabetes under TRICARE involves three main pillars: medical services, pharmacy benefits, and durable medical equipment (DME).

### 1. Doctor Visits and Education TRICARE covers office visits for diabetes management and specific **Diabetes Self-Management Training (DSMT)**. * **Initial Training:** Up to 10 hours of initial training is covered when ordered by a physician. * **Follow-up:** Up to 2 hours of follow-up training is allowed each subsequent year. * **Cost-sharing:** Active Duty Service Members (ADSMs) pay $0. For others, copays depend on whether you are in Group A or B and your plan (Prime vs. Select).

### 2. Pharmacy Benefits (Medications) Diabetes medications (insulin and oral drugs like Metformin) are managed by Express Scripts. * **Generic:** Typically $18 for a 90-day supply via mail order (2026 rates). * **Brand Name (Formulary):** Typically $48 for a 90-day supply via mail order (2026 rates). * **Non-Formulary:** $103 for a 90-day supply (2026 rates). * **Military Pharmacies:** $0 copay for most formulary drugs.

### 3. Equipment and Supplies (DME vs. Pharmacy) A major distinction in TRICARE diabetes coverage is how you receive your supplies:

*Note: Effective January 1, 2025, TriWest Healthcare Alliance manages these authorizations in the West Region, while Humana Military manages them in the East.*

### 4. Continuous Glucose Monitors (CGM) To qualify for a CGM (like Dexcom or FreeStyle Libre), a beneficiary must generally meet these criteria: * Diagnosis of diabetes mellitus. * Requirement for insulin injections (at least 3x daily) or an insulin pump. * Frequent blood glucose testing (4+ times daily). * The device must be FDA-approved.

## Who this applies to * **Active Duty Service Members:** 100% coverage with $0 out-of-pocket, but internal medical boards may review fitness for duty upon diagnosis. * **National Guard/Reserve:** Covered under TRICARE Reserve Select (TRS) following standard cost-shares and deductibles. * **Retirees:** Covered under TRICARE Prime or Select; subject to annual enrollment fees and higher copays for specialist visits. * **Medicare-Eligible Retirees:** TRICARE For Life (TFL) acts as second-payor to Medicare Part B for diabetes supplies.

Common scenarios

**Scenario 1: Retiree in TRICARE Select (Group A)** Jim is a retiree in the East Region using TRICARE Select. He visits an in-network endocrinologist for his Type 2 diabetes. In 2026, his specialist copay is $56. He fills his Tier 2 brand-name insulin via Express Scripts mail order, paying $48 for a 90-day supply.

**Scenario 2: Active Duty Spouse in TRICARE Prime** Sarah, an active duty spouse in the West Region (managed by TriWest), is pregnant and diagnosed with Gestational Diabetes. Because she is on Prime, her glucose monitor and specialist consultations are $0 out-of-pocket, provided she obtains the necessary referrals from her Primary Care Manager (PCM).

**Scenario 3: TFL Beneficiary needing an Insulin Pump** Robert is 70 and has TRICARE For Life. Medicare is his primary insurance. Medicare pays 80% of the cost for his insulin pump as DME. TRICARE For Life covers the remaining 20% "coinsurance," leaving Robert with $0 out-of-pocket for the device.

## Related terms * **Durable Medical Equipment (DME):** Reusable medical devices like insulin pumps or wheelchairs. * **Formulary:** The list of preferred brand-name and generic drugs covered by Express Scripts. * **Prior Authorization:** A requirement to get plan approval before certain services or expensive supplies (like CGMs) are covered. * **Cost-Share:** The percentage of the total cost a beneficiary pays (common in TRICARE Select). * **Medical Necessity:** The standard used to determine if a treatment or device is required for a specific diagnosis.
