Department of Public Health and Human Services must establish standardized cost reporting for Medicaid providers in adult mental health, children's mental health, substance use disorder, developmental disabilities, and senior/long-term care services

Providers must submit actual expenditure and revenue data in standardized format, with base-year data updated at least every 4 years but no more than once every 2 years

Department must produce a rate adequacy report at least every 4 years comparing Medicaid rates to provider costs, with the first report due September 1, 2026
