REQUIRED COVERAGE FOR CERTAIN AMINO ACID-BASED ELEMENTAL FORMULAS.

(a) A health benefit plan must provide coverage as provided by this chapter for amino acid-based elemental formulas, regardless of the formula delivery method, that are used for the diagnosis and treatment of:

(1) immunoglobulin E and non-immunoglobulin E mediated allergies to multiple food proteins;

(2) severe food protein-induced enterocolitis syndrome;

(3) eosinophilic disorders, as evidenced by the results of a biopsy; and

(4) impaired absorption of nutrients caused by disorders affecting the absorptive surface, functional length, and motility of the gastrointestinal tract.

(b) Subject to Subsection (c), the coverage required under Subsection (a) is required if the treating physician has issued a written order stating that the amino acid-based elemental formula is medically necessary for the treatment of an enrollee who is diagnosed with a disease or disorder listed in Subsection (a). The coverage must include coverage of any medically necessary services associated with the administration of the formula.

(c) A health benefit plan must provide the coverage described by Subsection (a) on a basis no less favorable than the basis on which prescription drugs and other medications and related services are covered by the plan, and to the same extent that the plan provides coverage for drugs that are available only on the orders of a physician.
