Establishes annual cost of living adjustment based on Consumer Price Index for programs providing mental health, substance use treatment, or services to persons with developmental disabilities.

New Jersey Assembly Bill A1143 establishes an annual cost-of-living adjustment (COLA) for mental health, substance use treatment, and developmental disability service programs. The COLA, based on the previous year's Consumer Price Index (CPI) from October 1 to September 30 (as published by the U.S. Department of Labor), must be included in state contracts for these programs starting on the bill's effective date. This applies to all state-funded programs - whether fully or partially Medicaid-funded - that are licensed or approved by New Jersey's Department of Human Services. The Department must announce the annual COLA rate each October 1, ensuring service providers receive regular inflation-based funding increases.
