The proposed bill aims to enhance access to mental health and substance use services in Washington by addressing significant disparities in coverage compared to medical and surgical services. It highlights findings from various analyses indicating that residents face considerable challenges in accessing in-network behavioral health services, with a notable gap in reimbursement rates for behavioral health clinicians compared to their medical counterparts. The bill emphasizes the need for greater transparency and accountability from health plans, particularly for youth who encounter even more barriers due to limited provider networks.

To achieve these goals, the bill introduces a new section to chapter 48.43 RCW, mandating that health carriers submit detailed annual reports on coverage and access data, including metrics on service utilization, reimbursement rates, and network adequacy. The data must be publicly accessible through a consumer-friendly dashboard, allowing for independent analysis and comparison across carriers. Additionally, the bill requires that all reported data be certified for accuracy by a designated officer of the carrier and retained for three years. The provisions of this act will apply to health plans issued or renewed on or after January 1, 2027.
