Medicaid Expansion and Buprenorphine Dispensing in Early vs Recent Expansion States

In this cross-sectional study using contemporary data and methods, post-2018 Medicaid expansions were associated with substantial increases in buprenorphine treatment, particularly in high-need states operating under newer prescribing regulations. These findings underscore Medicaid expansion's role in improving opioid use disorder treatment access and can inform state and federal efforts to expand evidence-based care.

Abstract

In this cross-sectional study using contemporary data and methods, post-2018 Medicaid expansions were associated with substantial increases in buprenorphine treatment, particularly in high-need states operating under newer prescribing regulations. These findings underscore Medicaid expansion's role in improving opioid use disorder treatment access and can inform state and federal efforts to expand evidence-based care.
