The bill establishes a new account known as the "medication for people living with HIV rebate revenue account" within the state treasury. This account will receive funds from pharmaceutical rebates generated through the purchase of medications for individuals living with HIV who are enrolled in the early intervention program. The funds deposited into this account, which include federal grant receipts, can only be used for services defined in the Ryan White HIV/AIDS program grant award. Expenditures from this account can be authorized solely by the secretary or their designee, and no appropriation is required for these expenditures.

Additionally, the bill reenacts and amends RCW 43.79A.040, which pertains to the management of the treasurer's trust fund and the investment income account. It specifies that the newly created HIV rebate revenue account will receive its proportionate share of earnings from the investment income account based on its average daily balance. The bill emphasizes the importance of this act for the immediate preservation of public health and safety, and it is set to take effect on July 1, 2023.
