Medicaid Unwinding and Changes in Buprenorphine Dispensing 

JAMA Network Open

Among Medicaid-insured adults with buprenorphine use, this cross-sectional study examined if changes in buprenorphine dispensing were greater among those residing in states with the highest vs lowest decreases in Medicaid enrollment after “Medicaid unwinding” began in April 2023. Researchers used 2017-2023 data from a national prescription dispensing database that included 754,675 person-years from 569,069 patients. They found that patients in states with the highest decreases in Medicaid enrollment were more likely to decrease buprenorphine use, discontinue buprenorphine therapy, and use private insurance or cash to pay for buprenorphine prescriptions. The finding that Medicaid unwinding was associated with disruptions in buprenorphine therapy raises concerns about the potential for increased opioid-related morbidity and mortality.
