## Quick answer In the TRICARE system, "feed" or nutritional support refers to specialized medical nutrition, such as enteral nutrition (tube feeding) or parenteral nutrition (IV feeding). TRICARE covers these services and supplies when they are medically necessary to treat a specific medical condition that prevents you from getting enough nutrients through normal eating.

## In detail TRICARE does not generally cover vitamins or standard groceries. However, it provides robust coverage for "medical nutrition" under specific guidelines managed by regional contractors (Humana Military in the East and TriWest Healthcare Alliance in the West).

### Covered Nutritional Support TRICARE covers enteral and parenteral nutrition when it is the primary source of nutrition and is required for the treatment of a diagnosed medical condition.

* **Enteral Nutrition (Tube Feeding):** This is liquid nutrition delivered via a tube into the stomach or small intestine. It is covered for patients who cannot swallow or have an anatomical/functional impairment of the gastrointestinal tract. * **Parenteral Nutrition (TPN/IV):** This is nutrition delivered directly into the bloodstream. It is covered when the GI tract is non-functional or when enteral feeding is not feasible. * **Specialized Formulas:** TRICARE covers specialized formulas for the treatment of Inborn Errors of Metabolism (IEM), such as Phenylketonuria (PKU), and for certain severe food allergies (e.g., cow's milk protein allergy) when specific criteria are met.

### Cost-Shares and Requirements (2026 Rates) Costs for nutritional supplies depend on your TRICARE plan and the setting where the "feed" is administered (home vs. outpatient clinic).

*Note: For Home Medical Equipment (DME) like feeding pumps, Prime members usually pay $0 when using a network provider with a referral.*

### What is NOT Covered TRICARE explicitly excludes the following: * Standard baby formula for healthy infants. * Protein shakes or meal replacement drinks (e.g., Ensure, Boost) used as a supplement to a regular diet. * Vitamin and mineral supplements (unless part of a specific IV therapy). * Food thickening agents.

## Who this applies to * **Active Duty Service Members (ADSMs):** Fully covered for all medically necessary nutritional support with $0 out-of-pocket. * **Active Duty Family Members (ADFMs):** Covered under Prime or Select; requires prior authorization for most home equipment. * **Retirees and their Families:** Covered, though subject to higher cost-shares and deductibles for equipment and formula prescribed for home use. * **Beneficiaries with Metabolic Disorders:** Those diagnosed with conditions like PKU or MSUD have specific coverage pathways for specialized medical "foods."

Common scenarios

**Scenario 1: Feeding Tube at Home** Sarah, a TRICARE Prime beneficiary in the West Region (managed by TriWest), requires a PEG tube and liquid formula due to esophageal cancer. Her doctor submits a prior authorization. Under 2026 Prime rules, Sarah pays **$0** for the feeding pump rental and the monthly delivery of her formula, provided she uses a TRICARE-authorized DME provider.

**Scenario 2: PKU Formula for a Child** A child on TRICARE Select (Group A) is diagnosed with PKU, requiring a highly specialized, expensive medical "feed" that serves as their primary protein source. Because this is for an Inborn Error of Metabolism, TRICARE Select covers the formula. The family pays their **20% cost-share** (2026 rate) after meeting their annual deductible.

## Related terms * **Durable Medical Equipment (DME):** The category under which feeding pumps and poles are classified. * **Enteral Nutrition:** Feeding that uses the gastrointestinal tract (oral or tube). * **Parenteral Nutrition:** Feeding that bypasses the GI tract, delivered via a vein (IV). * **Inborn Errors of Metabolism (IEM):** Genetic conditions that often require specialized medical diets. * **Prior Authorization:** A requirement to get approval from Humana Military or TriWest before receiving certain nutritional supplies.
