Section 1115 Demonstration Waiver for Substance Use Disorder (SUD) Treatment
Provider Resources
In alignment with the milestones of the Demonstration, SUD treatment services provided in the Medicaid fee-for-service (FFS) delivery system will comply with the current ASAM Criteria for activities including authorizations, utilization review decisions, multi-dimensional assessments and individualized treatment plans.
Application and Provider Certification and Monitoring:
Beginning in April 2022, following CMS approval of the 1115 SUD Demonstration waiver, Connecticut began accepting applications from providers for provisional certification to provide SUD services under the demonstration for a two-year period. The provisional certification period allows providers who meet a level of readiness, to provide services under the demonstration while making progress toward full adoption of the current version ASAM adopted by the state. The provisional period for residential providers began April 1, 2022, and ended April 1, 2024; Ambulatory providers began on November 15, 2022, Outpatient Hospitals on March 1, 2023, and Federally Qualified Health Centers (FQHCs) on July 1, 2023. Providers applying to provide services during a provisional period will have the remainder of the provisional period for the level of care for which they are applying to achieve full certification. Providers applying to provide services for a level of care for which the provisional period has ended must meet the level of readiness detailed in the 1115 SUD Certification Standards and Process and 1115 SUD Demonstration Application Guidance. Applications for provisional certification will not be accepted if the end date of the provisional period is within two-months.
