Bill Hanna State Medicaid Director Wisconsin Department of Health Services 1 W. Wilson St. Madison, WI 53701

Dear Director Hanna,

The Centers for Medicare & Medicaid Services (CMS) completed its review of the Substance Use Disorder (SUD) Monitoring Protocol, which is required by the Special Terms and Conditions (STC), specifically, STC #8.5 “Monitoring Protocol” of Wisconsin’s section 1115 demonstration, “Wisconsin BadgerCare Reform” (Project No: 11-W-00293/5), effective October 29, 2024 through December 31, 2029. CMS determined that the Monitoring Protocol, which was submitted on March 27, 2025, meets the requirements set forth in the STCs, and thereby approves the state’s SUD Monitoring Protocol.

The Monitoring Protocol is approved for the demonstration period through December 31, 2029 and is hereby incorporated into the demonstration STCs as Attachment B (see attached). In accordance with STC #9.11, the approved SUD Monitoring Protocol may now be posted to your state’s Medicaid website.

We look forward to our continued partnership on the Wisconsin BadgerCare Reform section 1115 demonstration. If you have any questions, please contact your CMS demonstration team.

Sincerely,

Danielle Daly Director Division of Demonstration Monitoring and Evaluation
