This report provides information on the progress of Alcohol and/or Drug (AOD) Treatment Expansion through the 2009 State Fiscal Year. The Treatment Expansion initiative has delivered a significant increase in AOD treatment penetration in Washington’s SSI-related Disabled Medicaid and GA-U populations. As predicted by the initial modeling for the Treatment Expansion initiative, the increase in AOD treatment penetration has coincided with a significant relative reduction in rates of growth in medical and nursing facility costs for Medicaid Disabled and GA-U clients with substance use problems. By “bending the curve” in health care costs, the AOD Treatment Expansion achieved an impressive return on investment in its first two biennia.
