1. The department shall provide coverage, subject to state and federal appropriations, for the full cost of amino acid-based elemental formulas, meaning formulas made from single nonallergenic amino acids, for children under nineteen years of age with a medical diagnosis of immunoglobulin E and nonimmunoglobulin E mediated allergies to multiple food proteins, food protein-induced enterocolitis syndrome, eosinophilic disorders, and impaired absorption of nutrients caused by disorders affecting the absorptive surface, functional length, and motility of the gastrointestinal tract.

2. The department may promulgate rules and regulations to implement the provisions of this section. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2015, shall be invalid and void.
