Substance Use Disorder Treatment

In response to the opioid crisis, Governor Eric Holcomb has prioritized attacking the drug epidemic on all fronts: prevention, treatment, and enforcement. The Indiana Family and Social Services Administration and Office of Medicaid Policy and Planning support this statewide priority and aim to ensure that all Hoosiers are provided the substance use disorder treatment they need in the most accessible manner. Further resources and descriptions of FSSA-OMPP initiatives related to SUD are provided on this page.

Section 1115 SUD demonstration waiver

Section 1115 of the Social Security Act gives states the flexibility to propose and implement innovative demonstration projects in an effort to better serve Medicaid populations. On February 1, 2018, the Centers for Medicare & Medicaid Services approved an extension to Indiana’s existing Section 1115 Medicaid demonstration waiver . The waiver now expands coverage for a full-range of SUD treatment services to Indiana Health Coverage Programs members enrolled in Traditional Medicaid (full, fee-for-service coverage) or in any managed care program - including Healthy Indiana Plan , Hoosier Care Connect and Hoosier Healthwise. Changes under the new SUD waiver include the following:

  • Expanding coverage of inpatient SUD treatment provided in institutions of mental disease
  • Adding coverage for short-term residential SUD treatment
  • Establishing a new provider type and specialty for residential treatment

Indiana’s Section 1115 SUD demonstration waiver is effective through December 31, 2020.

Strengthening the SUD delivery system: The SUD work group

Beginning in September 2018, the OMPP in coordination with the Division of Mental Health and Addiction, assembled an SUD work group to review the SUD demonstration waiver’s rollout, examine ways to improve upon delivery and coordination of new services and engage providers and stakeholders on best practices and ways to strengthen the delivery system.

The OMPP and DMHA are in the process of implementing recommendations from that initial effort, while continuing to collaborate across FSSA divisions and with stakeholder groups to identify and address new challenges in the SUD service delivery system. For more information on this project or individual initiatives to improve SUD treatment and access, please see the following resources:
