Coverage Criteria

Home enteral nutrition

Enteral nutrition formula and supplies are medically necessary when ALL of the following are met.

Qualifying permanent condition: The member has a permanent condition involving either full or partial non-function or disease of structures that normally allow food to reach the small bowel, or a disease impairing digestion or absorption such that tube feeding is needed to deliver adequate nutrition.Long and indefinite duration; at least 3 months meets the operational test
Examples include head and neck cancer, esophageal stricture or obstruction, and neurologic dysphagia with aspiration risk.
Nutrition and route requirements: Adequate nutrition is not possible through dietary adjustment or oral supplements; feeding is by nasogastric, gastrostomy, jejunostomy, or similar tube; and the gastrointestinal tract is functional enough to tolerate enteral feeding.

Prescription documentation:

The record documents the formula, total daily calories or volume, and administration method.

Administration may be by syringe, gravity, or pump.

Specialized enteral formula

A specialized enteral formula is medically necessary instead of a standard formula when ALL of the following are met.

Underlying enteral criteria: The member meets the home enteral nutrition criteria.
Reason standard formula is inadequate: The record documents intolerance such as diarrhea, vomiting, or malabsorption on a standard product; a disease-specific need such as an inborn error of metabolism, severe malabsorption, renal or hepatic failure, or fluid restriction; or a food-protein allergy requiring a hydrolyzed or amino-acid-based formula.

Enteral feeding pump

An enteral feeding pump is medically necessary when ALL of the following are met.

Underlying enteral criteria: The member meets the home enteral nutrition criteria.
Pump indication: Gravity or syringe feeding is inadequate or unsafe because of reflux or aspiration, severe diarrhea, dumping syndrome, a required administration rate below 100 mL per hour, significant blood glucose fluctuations, circulatory overload, or jejunostomy or gastrojejunostomy tube feeding.Below 100 mL per hour when rate is the indication

Home parenteral nutrition

Parenteral nutrition solutions, additives, supplies, and pump are medically necessary when ALL of the following are met.

Qualifying permanent impairment: The member has a permanent impairment involving either disease or resection of the small intestine or its exocrine glands that significantly impairs nutrient absorption, or disease of the stomach or intestine causing a motility disorder that impairs movement and absorption of nutrients.Long and indefinite duration; at least 3 months meets the operational test
Examples include short bowel syndrome, severe mucosal disease, radiation enteritis, chronic intestinal pseudo-obstruction, and severe dysmotility.
Enteral nutrition considered: The treating practitioner documents that enteral nutrition was considered and ruled out, tried and found ineffective, or worsens gastrointestinal dysfunction.
Examples include complete mechanical obstruction, a high-output fistula, or intractable vomiting or diarrhea on enteral feeding.
Pre-initiation evaluation: The treating practitioner evaluated the member before parenteral nutrition began.Within 30 days before initiation
Prescription and nutrient parameters: The prescription documents calories, protein, dextrose, lipid, and infusion schedule. Values outside the usual calorie or protein ranges require a documented clinical reason; dextrose concentration is at least 10 percent and lipid dosing follows FDA-approved product labeling.20–35 kcal/kg/day; 0.8–2.0 g/kg/day; dextrose at least 10 percent
Reasons for values outside usual ranges may include hypermetabolism, high-output losses, or pediatric growth needs.
Supplemental parenteral nutrition: When partial enteral or oral intake is tolerated but inadequate, supplemental parenteral nutrition is covered for the documented deficit.

State-required formula pathway

Where a state law in Appendix 1 applies to the member’s plan:

State-required formula pathway: A formula covered by the applicable state law is reviewed for medical necessity for the conditions listed in that law without applying this policy’s tube-feeding requirement.

Continuation and re-authorization

Continued enteral or parenteral nutrition is medically necessary when ALL of the following are met.

Continuation and re-authorization: The qualifying impairment persists, the current prescription is documented and quantities match it, and parenteral nutrition monitoring and reassessment are documented when applicable.Qualifying impairment documented at least every 12 months or sooner if the prescription changes

For parenteral nutrition, monitoring includes weight, fluid status, electrolytes, liver tests, and line condition; the plan must reassess the potential to advance enteral intake.

Texas amino acid-based elemental formulas

Texas state variance: review applies regardless of delivery method and without a tube-feeding requirement.

Texas amino acid-based elemental formula: The formula is used for diagnosis and treatment of IgE- or non-IgE-mediated allergies to multiple food proteins, severe food protein-induced enterocolitis syndrome, eosinophilic disorders evidenced by biopsy, or impaired absorption of nutrients caused by gastrointestinal tract disorders.

Florida home enteral formulas

Florida state variance: review applies without a tube-feeding requirement.

Florida home enteral formula: The formula is physician-prescribed for home use and medically necessary for an inherited disease of amino acid, organic acid, carbohydrate, or fat metabolism, or for malabsorption from a congenital defect present at birth or acquired in the neonatal period.

For amino acid and organic acid disorders, low-protein modified food products are included through age 24, up to $2,500 per year.

Oral nutritional supplements or formula taken by mouth when the member can meet nutritional needs orally are not addressed as covered services under this policy.

Infant formula that is not tube-fed is a benefit-design question and is not addressed by this policy.

Temporary tube feeding or parenteral nutrition for an impairment expected to resolve in less than 3 months does not meet the policy’s long-and-indefinite-duration requirement.

Parenteral nutrition is not medically necessary when the gut is functional and enteral feeding has not been considered, tried, or ruled out. Enteral feeding is preferred when the gut is usable.

A specialized formula is not medically necessary without documentation of intolerance, disease-specific need, food-protein allergy, or another reason a standard formula is inadequate.

An enteral feeding pump is not medically necessary when gravity or syringe feeding is documented as tolerated and safe.

Formula or solution quantities exceeding the documented caloric prescription are not supported. The supported quantity may be approved.

Provider Review and Authorization Actions

Prior Authorization

Medical-Necessity Review

Review each request against the applicable medical-necessity criteria in this policy and the member’s benefit plan before authorizing enteral or parenteral nutrition, supplies, solutions, additives, or pumps. Coverage remains subject to the member’s plan, applicable federal and state law, and other applicable requirements.

Denial Risk

Physician Review for Adverse Determinations

If the request may result in an adverse determination, offer the requesting practitioner a peer-to-peer discussion and refer the case to a licensed physician of the same or similar specialty. The reviewing physician must satisfy applicable licensure, specialty, and medical-director requirements for the plan’s situs state.

Documentation Required

Required Clinical Documentation

Include the diagnosis and mechanism of impaired nutrition—structural, neurologic, absorptive, or motility-related—along with the expected duration, why oral or enteral intake is inadequate, ruled out, or harmful, and the supporting clinical record. Document the nutritional prescription, relevant anthropometrics or pediatric growth parameters, and any specialized-formula or pump-specific rationale.

For parenteral nutrition, include practitioner evaluation within 30 days before initiation and monitoring laboratory results.
Document formula or solution, calories, protein, volume, administration method or infusion schedule, and the reason standard formula or gravity/syringe feeding is inadequate when applicable.

Documentation Required

Prescription and Ongoing Monitoring

Document the current formula or solution, calories, volume, protein where applicable, and administration method or infusion schedule; requested quantities must match the prescription. For ongoing parenteral nutrition, document weight, fluid status, electrolytes, liver tests, line condition, and reassessment of whether enteral intake can be advanced.

The qualifying impairment must be re-documented at least every 12 months, or sooner when the prescription changes.
Parenteral nutrition prescriptions should address calories, protein, dextrose, lipid, and infusion schedule; clinical reasons are required for values outside policy ranges.

Billing Rule

Support Requested Quantity and Duration

Ensure the clinical documentation supports every requested unit, quantity, and duration. When the service qualifies but only part of the request is supported, approve the supported portion and route the unsupported increment for separate physician review rather than treating the entire request as unsupported.

Denial Risk

Does Not Meet Medical-Necessity Criteria

Requests may not meet medical-necessity criteria when nutrition can be provided orally, the impairment is temporary or expected to resolve in less than 3 months, the gut is functional and enteral feeding has not been considered or tried, or documentation does not support the requested service. Other denial risks include specialized formula without an inadequate-standard-formula rationale, a pump when gravity or syringe feeding is safe, and quantities exceeding the documented prescription.

Supplemental parenteral nutrition may be appropriate when partial oral or enteral intake is tolerated but inadequate; document the deficit.
A request that does not meet criteria must be referred for physician review and may not be adversely determined by an automated system or non-physician reviewer.

Billing Rule

Quantity, Refill, and Pump Limitations

Match enteral supply kits to the administration method and bill kits per day. Observe refill, delivery, and pump limits when ordering or authorizing supplies.

Refill contact may occur no sooner than 30 days, and delivery no sooner than 10 days, before current supplies are exhausted.
Limit coverage to one enteral or parenteral pump per member unless a backup pump is supported by documented need, such as continuous use exceeding 20 hours per day or pediatric status.
Enteral kits include all supplies except enzyme cartridges.

Denial Risk

Physician Determination Authority

Automated systems and non-physician clinical reviewers may approve a request in full or in part, but they may not issue an adverse determination. Non-qualifying requests must be referred to a licensed physician for determination under applicable plan and state requirements.

Denial Risk

Criteria Not Met

When an applicable medical-necessity criterion is not met, refer the request for physician review before issuing any adverse determination. The absence of a criterion specifically addressing a service is not, by itself, a basis for denial; a physician must apply generally accepted standards of medical practice.

Denial Risk

Unsupported Quantity or Duration

If documentation supports the service but not the full requested quantity, units, or duration, approve the supported portion when appropriate and separately review only the unsupported increment. The requesting practitioner must have the opportunity for peer-to-peer discussion before an adverse determination is issued.

Policy Background

Enteral nutrition delivers nutrients through the gastrointestinal tract, typically by tube, when oral intake cannot provide adequate nutrition. Parenteral nutrition provides nutrients intravenously when intestinal function is insufficient or enteral feeding is inadequate, ineffective, or harmful. Both approaches may replace the nutritional function of an inoperative or malfunctioning internal organ. When the gastrointestinal tract is functional, enteral nutrition is preferred; parenteral nutrition is generally reserved for intestinal failure or circumstances in which enteral nutrition cannot safely or effectively meet nutritional needs.
