This bill creates a new state treasury account called the "medicaid enhanced provider rate account" by adding new sections to chapter 74.09 RCW and requires the state treasurer to transfer, at the beginning of each fiscal year, from the general fund into that account the amount calculated by "the authority." Moneys in the account may be spent only after appropriation and only for increased Medicaid reimbursement rates to providers and hospitals. The measure is a procedural and fiscal change to state law establishing a dedicated funding account and a new annual reporting and transfer mechanism; it does not create a criminal offense or change penalties. The bill requires "the authority" to annually (by June 30) calculate and report to the legislature’s fiscal committees the amount of state Medicaid expenditures that would have been made under federal and state law in effect before July 1, 2025, but were not made because of reforms in P.L. 119-21. The calculation must include specified categories of decreased state expenditures or lapsed appropriations (six categories are identified, including items tied to Medicare savings programs, the medical assistance program (Title XIX), the state children’s health insurance program (Title XXI), and Medicaid expansion enrollees) and must describe the methodology and data sources used. The act declares an emergency and takes effect immediately. The text provided does not identify or define "the authority," does not give the new section numbers added to chapter 74.09 RCW, and does not include the specific calculation methodology or additional appropriation, oversight, or distribution mechanics beyond the high-level requirements described.

If enacted, the state will create a dedicated treasury account intended to pay for higher Medicaid reimbursement rates for providers and hospitals, with the treasurer required each fiscal year to move into that account an amount calculated annually by "the authority." That calculated amount is supposed to represent state Medicaid spending that did not occur because of federal reforms in P.L. 119-21, and the authority must report the prior fiscal year’s calculation to the legislature’s fiscal committees by June 30. Providers and hospitals are the likely beneficiaries if the legislature appropriates those funds, while the state treasurer and the unspecified "authority" take on new annual transfer and reporting duties. Key uncertainties change practical outcomes: the bill text does not identify who "the authority" is, does not include the calculation method, and leaves appropriation, oversight, and distribution mechanics unspecified. As a result, any additional money for provider rates depends on the authority’s report and then on the legislature choosing to appropriate those funds; the general fund will be reduced by whatever amount is transferred each year, and the authority will face a new workload and potential scrutiny for its calculations.
