Changes in Residential Substance Use Treatment Service Access Resulting From Recent Medicaid Section 1115 Waivers.

Medicaid stands to play a significant role in addressing the needs of individuals with a substance use disorder; however, many state Medicaid programs do not cover a full continuum of care. A growing number of states are taking advantage of Section 1115 demonstration waivers to augment their covered benefits, including experimenting with financing residential treatment services that previously were not eligible for reimbursement. Concerns over potential overuse of these services or increased spending due to this service expansion may be tempered by complementary delivery system transformation focused on reining in costs and improving care quality.
