Coverage Summary

This policy defines medical necessity, prior authorization, documentation, and coding guidance for coverage of enteral formulas, nutritional supplements, and digestive enzyme cartridges (e.g., RELiZORB) for Mass General Brigham Health Plan members. It applies across Commercial, MassHealth, and Medicare Advantage populations and requires prior authorization with supporting clinical documentation. High-level exclusions include use of enteral products for non-medical purposes (e.g., as regular food or for weight loss), coverage does not extend to standard commercial infant formulas when not medically necessary, and requests submitted through a non-certified DME provider will not be authorized.

Quick thresholds and facts

RELiZORB minimum age>= 2 years

RELiZORB continuous feed duration>= 6 hours continuous and requires overnight enteral feeds

RELiZORB initial authorization duration6 months

Prematurity gestational age<= 36 weeks gestation (formulas may be covered up to 3 months of age)

Adult weight loss threshold>= 10% involuntary weight loss over 3–6 months

Adult BMI thresholdBMI < 18.5 kg/m2

Commercial annual low‑protein foods limitUp to $5,000 per year for low‑protein food products (Commercial accounts only)

Medically Necessary Criteria

Medical necessity for nutritional formula or supplements administered orally or via enteral tube is established when ONE of the following conditions is met:

ANY of the following

General therapeutic enteral nutrition: Enteral nutrition, orally or by tube feeding, when used as a therapeutic regimen to prevent serious disability or death in a member with a medically diagnosed condition that precludes the full use of regular food or precludes adequate ingestion of calories to achieve sufficient growth.
Prematurity: Formulas formulated for premature infants born at less than or equal to 36 weeks gestation; may be covered for up to 3 months of age. Documentation required includes gestational age.<= 36 weeks gestation; coverage up to 3 months of age
Clinical signs and symptoms / nutritional risk

Not Covered / Exclusions

Excluded/not-covered scenarios include enteral products used for non-medical purposes or as supplementation to a normal diet when nutritional needs can be met with regular food or store-bought supplements; standard commercial or WIC infant formulas for Commercial members (unless medically necessary quantities beyond WIC allowance are documented); and the explicit policy exclusion that authorizations will not be provided for requests submitted through a non-certified DME provider. Prior authorization and adequate clinical documentation are required; absence of a medical history/physical or documentation supporting need is a basis for noncoverage.

Provider Actions & Authorization Requirements

Background & Definitions

Background: the policy references Massachusetts state mandates for coverage of formulas for inborn errors of amino/organic acid metabolism (including a Commercial $5,000 annual limit for low-protein food products) and notes authorization durations and annual review requirements for state‑mandated conditions. Medicare Advantage determinations follow CMS LCDs/LCAs where applicable. The policy excludes standard commercial formulas and non-medical uses and specifies detailed documentation and prior authorization requirements for enteral products and digestive enzyme cartridges.

Term	Definition
Enteral Formula	Liquid nourishment, which may be given through a feeding tube.
Supplements	Liquid nourishment taken by mouth and usually not associated with regular store-bought food, such as instant breakfast drinks or protein powder drinks.
Malabsorption	A problem properly absorbing nutrition from food, potentially or actually leading to malnutrition.
Malnutrition	A pathologic state caused by deficiency, excess or imbalance of essential nutrients; primary or secondary causes.
Combined MCO Medical Necessity Review Form for Enteral Nutrition Products	Standardized form completed by the prescriber for establishing medical necessity for prior authorization.
Digestive enzyme cartridge	A cartridge containing lipase designed to mimic pancreatic lipase action to increase fat absorption from enteral nutrition (e.g., RELiZORB).

Inability to ingest regular food / swallowing impairment: The member cannot ingest regular food because of a medical condition or has a medical condition causing difficulty with swallowing and inability to take nutrition by mouth.

Evidence of weight loss (adults/post-pubertal)

Adult weight/BMI thresholds: Adults and post-pubertal adolescents: involuntary or acute weight loss >= 10% of usual body weight during a 3- to 6-month period, or BMI below 18.5 kg/m2; for members with chronic immobility where height is difficult to measure, another anthropometric method (e.g., arm span) may be used.>= 10% weight loss; BMI < 18.5 kg/m2

Pediatric growth criteria

VLBW: Very low birth weight (VLBW <1500 g) within the first three months of life corrected for prematurity even in the absence of gastrointestinal, pulmonary, or cardiac disorders.VLBW <1500 g within first 3 months corrected age
Sustained decrease in weight percentiles: Sustained decrease in weight or weight-for-height-for-age-and-gender across two or more major percentiles after previously stable growth (growth velocity).two or more major percentiles decrease
Lack of weight gain - infants: Lack of weight gain, or weight <2 standard deviations below the age-appropriate mean, and not growing at a rate parallel to the growth curve in a three-month period for children under six months or four-month period for children six to 12 months, not reversed with appropriate diet instruction.< -2 SD or not gaining in specified period
No weight gain - older children: No weight gain or slow rate of gain for six months for children older than one year, and/or documented weight loss not reversed promptly with appropriate diet instruction.6 months no/slow gain
