TRICARE Coverage for Feeding and Enteral Nutrition
*TRICARE.Com is an independent reference site and is not the official TRICARE program or a government agency. For official policy, visit TRICARE.mil.*
## Quick answer TRICARE covers enteral nutrition (tube feeding) when it is the primary source of nutrition for patients who cannot chew or swallow due to illness, injury, or surgery. The plan generally does not cover oral nutritional supplements (liquids like Ensure or Boost taken by mouth) unless they are used to treat very specific metabolic disorders, such as PKU.
## In detail TRICARE’s coverage for feeding depends heavily on the **method of delivery** and the **underlying medical condition**. TRICARE distinguishes between regular food, nutritional supplements, and medical "feed" required for survival.
### Enteral Nutrition (Tube Feeding) TRICARE covers enteral nutrition—food provided via a tube into the stomach or small intestine—under the following conditions: * The patient has a physical impairment that prevents them from swallowing or chewing. * The feeding is necessary to sustain life or prevent severe malnutrition. * The supplies (pumps, bags, tubes) are considered Durable Medical Equipment (DME).
### Oral Nutritional Supplements In most cases, TRICARE does not cover nutritional supplements taken orally. However, there is a major exception for **Medical Foods** used to treat: * Inborn Errors of Metabolism (IEM), such as Phenylketonuria (PKU). * Certain severe malabsorption syndromes. * High-protein formulas required for recovery from massive burns (specifically when prescribed by a doctor).
### Costs and Cost-Shares (2026 Rates) Costs depend on your plan and beneficiary status (Group A or Group B). * **TRICARE Prime:** Usually $0 out-of-pocket for medically necessary enteral supplies and formula when obtained through a network provider or military clinic. * **TRICARE Select (Group A Retirees):** May face a 20% cost-share of the TRICARE-allowed amount for DME and supplies once the deductible is met. * **Pharmacy Benefit:** Special metabolic formulas are often processed through the pharmacy benefit managed by **Express Scripts**.
### Regional Management * **East Region:** Managed by Humana Military. * **West Region:** Managed by TriWest Healthcare Alliance. * **Overseas:** Managed by International SOS.
Specialty formulas often require **Prior Authorization**. Your provider must submit medical records proving the patient cannot survive on a normal diet.
## Who this applies to * **Active Duty Service Members (ADSMs):** Fully covered for all medically necessary feeding supplies with $0 out-of-pocket. * **Active Duty Family Members (ADFMs):** Covered for tube feeding and metabolic formulas; costs vary by Prime vs. Select. * **Retirees and Families:** Covered for enteral nutrition, but subject to 2026 cost-shares and enrollment fees. * **Patients with Neurological Disorders:** (e.g., ALS, Parkinson’s) who have lost the ability to swallow. * **Infants with Metabolic Disorders:** Covered for specialized medical formulas that are not available over-the-counter.
Common scenarios
**Scenario 1: Tube Feeding at Home** John is a retired veteran (Group B) on TRICARE Select West. Due to throat cancer, he requires a J-tube and monthly formula deliveries. In 2026, after meeting his deductible, John pays a 20% cost-share for his monthly formula and pump rentals through TriWest’s network of DME providers.
**Scenario 2: Infant with PKU** A child of an Active Duty family in the East Region is diagnosed with PKU. They require a highly specialized, low-protein medical formula. Because this falls under the "Inborn Errors of Metabolism" exception, TRICARE covers the formula through the pharmacy benefit (Express Scripts) at a $0 copay.
**Scenario 3: Standard Supplement Use** Sarah, a TRICARE Prime beneficiary, is told by her doctor to drink Ensure to gain weight after a surgery. Because Sarah is able to swallow and the supplement is available over-the-counter, TRICARE does not cover the cost. Sarah pays 100% out-of-pocket at the grocery store.
## Related terms * **Durable Medical Equipment (DME):** The hardware used for feeding, such as IV poles or electronic pumps. * **Enteral Nutrition:** Nutrients delivered directly into the gastrointestinal tract via a tube. * **Parental Nutrition (TPN):** Nutrients delivered intravenously (through the veins), also covered by TRICARE when medically necessary. * **Prior Authorization:** The requirement to get TRICARE's "okay" before receiving specialty formulas or equipment. * **Medical Food:** Food formulated to be consumed or administered enterally under the supervision of a physician for the specific dietary management of a disease.
