## Quick answer TRICARE provides comprehensive coverage for loss of limb, including emergency surgery, inpatient rehabilitation, and the fitting of prosthetic devices. Coverage includes high-tech "myoelectric" limbs and repair/replacement costs, provided they are deemed medically necessary by a TRICARE-authorized provider.

## In detail Loss of limb (amputation) involves complex care coordination across multiple TRICARE benefit categories. The program defines coverage based on medical necessity rather than "cosmetic" appearance.

### Prosthetic Devices TRICARE covers prosthetic limbs that replace a body part or improve the function of a malformed body part. * **Initial Fitting:** Coverage includes the device, the fitting, and the training required to use it. * **Technology levels:** TRICARE generally covers advanced prosthetics, including myoelectric (muscle-activated) limbs, if a physician documents that the beneficiary has the cognitive and physical ability to operate the device. * **Replacements:** Costs are covered if the device is lost, irreparably damaged, or if the patient’s physical condition changes (e.g., bone growth in children or significant weight loss/gain).

### Rehabilitation Services Post-amputation care is typically managed through: * **Inpatient Rehabilitation:** Covered when intensive, multi-disciplinary therapy is required immediately following surgery. * **Occupational and Physical Therapy:** TRICARE covers these services to help beneficiaries regain mobility and independence. Active Duty Service Members (ADSMs) often receive this care at Military Treatment Facilities (MTFs) or specialized "Centers of Excellence."

### Costs and Copays (2026 Rates) Costs vary significantly based on the beneficiary’s plan and whether the care is received in-network.

*Note: "Group A" includes those whose initial enlistment or appointment was before Jan. 1, 2018. "Group B" is for those who joined on or after that date.*

### Regional Contractors While Express Scripts manages the pharmacy side of pain management, your regional contractor handles the authorizations for high-cost prosthetics: * **East Region:** Humana Military * **West Region:** TriWest Healthcare Alliance (Effective Jan 1, 2025)

## Who this applies to * **Active Duty Service Members:** Receiving 100% covered care, often through the Advanced Rehabilitation Centers (ARCs) at major military hospitals. * **Medically Retired Veterans:** Coordination may shift between TRICARE and the Department of Veterans Affairs (VA) depending on the "Line of Duty" status. * **Military Spouses and Dependents:** Coverage is provided for congenital limb differences or amputations resulting from accidents or disease (e.g., diabetes-related complications). * **TRICARE For Life (TFL) Users:** For those with Medicare, TRICARE acts as the second payer for prosthetic costs.

Common scenarios

**1. Active Duty Soldier (Traumatic Injury)** An Army Sergeant loses a leg in a non-combat motorcycle accident. Under **TRICARE Prime**, 100% of the surgery, a $40,000 microprocessor-controlled knee, and months of physical therapy are covered with **$0 out-of-pocket costs**, provided care is coordinated through TriWest (West) or Humana Military (East).

**2. Retired Dependent (Diabetes-Related)** The spouse of a retired Navy Commander (Group A, TRICARE Select) requires a below-the-knee amputation due to complications from diabetes. If the prosthetic costs $12,000, the family would be responsible for a **20% cost-share ($2,400)** after their annual deductible is met, up to the annual Catastrophic Cap.

**3. Child of Service Member (Congenital)** A child born with a limb difference requires a new prosthetic every 12–18 months due to growth. TRICARE covers these **recurring replacements** as medically necessary upgrades, with costs determined by the sponsor’s specific plan type (Prime vs. Select).

## Related terms * **Durable Medical Equipment (DME):** The category under which most prosthetic hardware is billed and authorized. * **Myoelectric:** A type of prosthetic that uses electrical signals from the user's muscles to move the limb. * **Catastrophic Cap:** The maximum out-of-pocket amount a family pays per year; essential for limb loss care which often reaches this limit quickly. * **Line of Duty (LOD) Determination:** A finding that confirms an injury occurred during service, affecting long-term VA vs. TRICARE benefits. * **Centers of Excellence:** Specialized DoD facilities (like Walter Reed) that provide world-class amputation care.
