On October 8, 2021, California Governor Gavin Newsom announced that he would be vetoing SB 110. SB 110 would have allowed the California state Medicaid program, Medi-Cal, to provide contingency management as a covered benefit for treating substance use disorders (SUDs). Prescription digital therapeutics (PDTs) deliver contingency management treatment. PDTs are evidence-based medical interventions that use software that can be accessed on a tablet or smartphone to prevent, manage, or treat SUDs. Fortunately, in the veto, the Governor also announced that a pilot study on Medi-Cal and a contingency management benefit would occur from January 2022 through March 2024. We encourage the state to use this pilot program to explore PDTs as an adjunct to contingency management for patients who may benefit from it. Governor Newsom’s veto letter can be read here.
