(1) Beginning July 1, 2021, the partnership access lines described in RCW 71.24.061(3)(a), the psychiatric consultation line described in RCW 71.24.062, and the first approach skills training program described in RCW 71.24.061(3)(a)(iv) shall be funded as follows:

(a) The authority, in consultation with the University of Washington department of psychiatry and behavioral sciences and Seattle children's hospital shall determine the annual costs of operating each program, as well as the authority's costs for administering the programs.

(b) For each program, the authority shall calculate the proportion of clients that are covered by programs administered pursuant to chapter 74.09 RCW. The state must cover the cost for programs administered pursuant to chapter 74.09 RCW through state and federal funds, as appropriated.

(c)(i) The authority shall collect a proportional share of program costs from each of the following entities that are not for covered lives under contract with the authority as medicaid managed care organizations:

(A) Health carriers, as defined in RCW 48.43.005;

(B) Self-funded multiple employer welfare arrangements, as defined in RCW 48.125.010;

(C) Employers or other entities that provide health care in this state, including self-funding entities or employee welfare benefit plans.

(ii) For entities listed in (c)(i) of this subsection, a proportional share of the entity's annual program costs for each program must be calculated by determining the annual cost of operating the program not covered under (b) of this subsection and multiplying it by a fraction that in which the numerator is the entity's total number of resident insured persons among the population served by the program and the denominator is the total number of residents in the state who are served by the program and not covered by programs administered pursuant to chapter 74.09 RCW. The total number of resident insured persons among the population served by the program shall be determined according to the covered lives per calendar year determined by covered person months.

(iii) The entities listed in (c)(i) of this subsection shall provide information needed to calculate the proportional share of program costs under this section to the authority.

(d) The authority's administrative costs for these programs may not be included in the assessments.
