NASPGHAN/ESPGHAN guidance.
NICE, CF Foundation, ESPEN, Academy/ASPEN guidance cited.
The policy lists items that are generally not covered. These include: specialized formula when the Coverage Rationale oral nutrition criteria are not met; standard formula for oral intake; self‑blenderized formulas for oral intake; enteral formula additives for oral intake; electrolyte‑containing fluids for oral intake used to replace fluids and electrolytes; nutritional or cosmetic therapies using high‑dose or “mega” quantities of vitamins, minerals, or elements (examples given include high‑protein, low‑protein, and low‑carbohydrate foods and supplements); formulas for treatment of mild and moderate food allergies or food intolerance; and oral nutrition provided solely for lack of appetite or cognitive conditions
No explicit additional exclusions are stated in the referenced policy fragments. Providers should consult applicable federal, state, or contractual benefit terms for any plan‑specific exclusions that may apply.
For informational context the policy notes that medical foods are regulated as foods, not drugs under the Orphan Drug Act/FDA definitions. The policy emphasizes that FDA approval alone is not a basis for coverage and refers providers to FDA guidance on medical foods for further regulatory detail.
When applying this policy providers must follow any applicable federal, state, or contractual requirements for benefit plan coverage. In cases of conflict, those external requirements govern, and the policy advises checking the governing benefit terms before use.
The policy explicitly notes that formulas intended for mild or moderate food allergies or food intolerance and standard formulas for oral intake are generally not covered, reinforcing that such uses do not meet the coverage rationale unless specific oral nutrition medical necessity criteria are satisfied.
No explicit statements labeling services or items as "not medically necessary" appear in the cited fragments beyond the general exclusions and guidance already provided; clinical applicability should be verified against the full coverage criteria and any applicable state or contractual rules.

Provider Requirements and Authorization
Prior authorization required per PA PROMISe for adults
For members age 21 and older, prior authorization is required and medical necessity clinical coverage criteria are governed by the Pennsylvania PROMISe™ Provider Handbook (837 Professional/CMS 1500 Claim Form § 7.1.2.3) for Prior Authorization of Enteral Nutrition; tube‑feeding clinical criteria reference InterQual for specific triggers.
- Applicable HCPCS codes cited elsewhere in the policy include B41xx and S943x for enteral formulas and medical foods.
No additional in-policy prior authorization process specified
This document does not list a separate, explicit prior authorization process or unique PA-level billing modifiers beyond the referral to the PROMISe™ Provider Handbook; providers should follow the referenced state handbook for submission and approval steps.
- No other explicit prior authorization instructions are presented in this policy text.
Follow Pennsylvania PROMISe™ Provider Handbook for PA prior auth
State‑specific prior authorization for enteral nutrition must follow the Pennsylvania PROMISe™ Provider Handbook instructions for the 837 Professional/CMS 1500 Claim Form § 7.1.2.3: Prior Authorization of Enteral Nutrition.
- Providers must use PROMISe™ guidance for Pennsylvania-specific submission and clinical criteria.
Pennsylvania prior authorization and criteria governed by PROMISe™
Prior authorization requirements and the medical necessity clinical coverage criteria for enteral nutrition are governed by the Pennsylvania PROMISe™ Provider Handbook (837 Professional/CMS 1500 Claim Form § 7.1.2.3).
- This policy replaces previous instruction to refer to the Pennsylvania Medical Assistance Bulletin with PROMISe™ Handbook direction.
Step therapy: no in‑policy sequencing — standard formula acceptable for tube feeding
Standard formula may be used for tube feeding when standard foods cannot be administered through a tube; the policy does not impose a step‑therapy sequence within the document.
- For tube feeding, standard formula can be considered medically necessary for that route of administration.
Formula trial recommendation: hydrolyzed before amino acid in many infants
Clinical guidance recommends trialing extensively hydrolyzed formulas for ~2–4 weeks before progressing to an amino acid–based formula in many infants with suspected reflux or cow's milk protein–related symptoms; amino acid formula is indicated if symptoms fail to resolve or for failure to thrive.
- NASPGHAN/ESPGHAN suggest a 2–4 week trial of extensively hydrolyzed protein (or amino acid–based formula) after optimal nonpharmacologic treatment has failed.
- Amino acid formula is recommended when symptoms do not resolve with hydrolyzed formula or in more severe presentations (e.g., failure to thrive).
Required clinical documentation and prescription
Prescribe specialized enteral formulas only with a clinician prescription and documentation that the condition is chronic and expected to be prolonged, and that adequate nutrition cannot be achieved by dietary adjustment; Medical Foods must be administered under physician supervision.
- Prescription must be by a physician, advanced practitioner, or registered dietitian.
- Documentation should demonstrate diagnosis, duration, prior dietary attempts, and need for ongoing medical supervision.
Denial risk if oral nutrition criteria are not met
Requests for specialized formula when the Coverage Rationale oral nutrition criteria are not met are generally not covered and may be denied.
- Examples of not-covered situations include standard formula for oral intake, self‑blenderized oral formulas, and formulas for mild/moderate food allergies or food intolerance.
Prior authorization submission and referral requirement — noncompliance may deny claim
Failure to follow the Pennsylvania PROMISe™ Provider Handbook § 7.1.2.3 prior authorization requirements may result in claim denial; providers must submit prior authorization per PROMISe™ with the supporting clinical documentation required by that handbook.
- Follow PROMISe™ submission instructions for the 837 Professional/CMS 1500 Form § 7.1.2.3 and include required clinical documentation.
Follow federal, state, or contractual requirements where they differ
Coverage determinations under this policy must follow applicable federal, state, or contractual benefit plan requirements when those conflict with the policy; providers should check benefit terms and applicable laws before applying this policy.
- UnitedHealthcare may use third‑party tools such as InterQual to assist in benefit administration, but federal/state/contractual terms govern in the event of conflict.
Documentation and claim form guidance — use PROMISe™ instructions
Providers must follow PROMISe™ Provider Handbook prior authorization and 837 Professional/CMS 1500 claim form instructions for documentation and claim submission when seeking coverage for enteral nutrition in Pennsylvania.
- Include clinical records demonstrating diagnosis, chronicity, prior dietary attempts, and the prescribing clinician as required by PROMISe™.
Verify federal/state/contractual benefit rules; InterQual may be used for tube feeding criteria
Providers must check and follow federal, state, or contractual benefit plan requirements prior to using this policy; UnitedHealthcare may use InterQual® criteria to assist benefit administration but state or contractual rules take precedence.
- For members under 21, tube‑feeding clinical criteria reference InterQual® CP: Durable Medical Equipment, Enteral and Parenteral Nutrition Therapy.
Required Documentation and Submission
Keep clinical records showing diagnosis, prior trials, duration, and prescription
Maintain clinical records documenting diagnosis, duration, prior dietary attempts, and the prescribing clinician’s information; show that adequate nutrition cannot be achieved by dietary adjustment and that medical supervision is in place for Medical Foods.
- Include documentation of prior dietary trials and objective evidence of malnutrition or risk of severe outcomes when applicable.
Submit PA per PROMISe §7.1.2.3 with required clinical documentation
Submit prior authorization requests according to the Pennsylvania PROMISe™ Provider Handbook § 7.1.2.3 and include the supporting clinical documentation required by that handbook.
- Use the PROMISe instructions for 837 Professional/CMS 1500 claim form submission and required attachments.
Follow PROMISe and CMS‑1500 guidance for Medical Food documentation and claims
Treat enteral nutrition products as Medical Foods administered under physician supervision and follow Pennsylvania PROMISe™ Provider Handbook instructions and 837 Professional/CMS 1500 claim form guidance for documentation and claim submission.
Use PROMISe handbook for PA documentation and submission instructions
Refer to the Pennsylvania PROMISe™ Provider Handbook for detailed prior authorization documentation requirements and any state‑specific submission instructions.
Check applicable federal/state/contract requirements and InterQual use
Verify federal, state, or contract benefit plan requirements before applying this policy; UnitedHealthcare may use third‑party tools (for example, InterQual®) to assist in administering benefits.

Background and Scope
Enteral nutrition delivers nutrients via the gastrointestinal tract by oral intake, liquid supplements, or tube feeding. Formulas are available as standard formulas (intact nutrients) or as specialized nutrient formulas / medical foods intended to meet distinctive nutritional needs for specific disease states and administered under physician supervision. Place‑of‑service for medical foods is typically in medical settings or under medical supervision, and enteral nutrition may be provided in inpatient, outpatient, or home settings depending on clinical need and monitoring requirements.
