Non-function or disease of structures: Patient has permanent non-function or disease of the structures that normally permit food to reach or be absorbed from the small bowels.

Question 2 on form must be answered Y/N/D

Need for tube feedings: Patient requires tube feedings to provide sufficient nutrients to maintain weight and strength commensurate with overall health status.

Provider Submission and Documentation Requirements

Documentation Required

CMN Submission Requirement

Submit a completed Certificate of Medical Necessity (CMN) signed by the physician along with a typed office note that contains pertinent clinical information to support coverage. Physician signature stamps are not acceptable.

Include the completed CMN with all patient identifiers and the physician signature (no stamped signatures).
Attach a typed office note that explains the diagnosis, clinical status, and reasons enteral nutrition is medically necessary.

Documentation Required

Required Documentation

Required documentation must answer the clinical questions on the CMN and provide supporting details for medical necessity.

Completed CMN with patient name and ID, responses to clinical questions (diagnosis, non-function of oral/enteral route, need for tube feeding, percent of calories from formula, product names, calories per day, days per week administered, method of administration, documented intolerances/allergies, and formulation details if required).
Typed office note with relevant exam findings, weight/nutritional status, estimated caloric needs, anticipated duration of enteral support, and rationale for chosen formula/method.

Denial Risk

Missing Documentation — Denial Risk

Failure to provide a typed office note with the completed CMN and required clinical details may result in denial of the request.

Incomplete CMNs or missing physician signature (or use of signature stamp) can lead to processing delays or denial.
Omitting the typed office note or not addressing the CMN clinical questions increases risk of denial.

Note

Provider Action

Provider action: ensure all CMN fields are completed and submit both the signed CMN and the typed office note together to avoid delays.

Verify physician signature is hand-signed and date is included.
Ensure product names, administration method (syringe/gravity/pump), frequency, and calorie information are documented.

Background

Enteral nutrition (tube feeding) provides nutrients directly into the gastrointestinal tract for patients who cannot consume or absorb adequate nutrition by mouth because the structures that normally permit food to reach or be absorbed from the small bowel are permanently nonfunctional or diseased. The CMN captures the clinical rationale by asking for the patient’s diagnosis, confirmation of non-function or disease of the relevant GI structures, whether the patient requires tube feedings to maintain weight and strength, the percentage of calories to be provided by enteral formula, product names and calories per day, days per week administered, method of administration (syringe, gravity, pump, or N/A), and documentation of any intolerance or allergy or need for a specialized formulation. A typed office note with pertinent information and the physician’s signature must accompany the CMN.

Key Definitions

Enteral Nutrition — definition for tube feeding / provision of nutrients into GI tract

TermEnteral Nutrition

DefinitionProvision of nutrients directly into the gastrointestinal tract (e.g., via tube feeding) when oral intake is inadequate or impossible.

Typical useUsed when patients cannot consume or adequately absorb nutrients via the normal oral route due to non-functioning or diseased structures of the upper GI tract.

Administration routesDelivered into the GI tract by tube feeding methods such as syringe, gravity, or pump (form selection and method documented on CMN).

Certificate of Medical Necessity (CMN) — definition and purpose

Required elementsDiagnosis, permanence/non-function of GI structures, need for tube feedings, percent of calories from enteral formula, product names, calories/day, days per week, method of administration, documented intolerances/allergies, and details if specialized formulation is required.

Provider signaturePhysician signature required on the CMN (stamps are not acceptable).

Supporting documentationTyped office note with pertinent information must accompany the completed CMN (requested information on form).
