^a Totals for OTP users are smaller than in Table 1 because the population was limited to those with 12 months of Medicare Part B coverage in 2022, with no enrollment in Medicare Advantage.

^b The race and ethnicity variable comes from the Beneficiary Race Code from the Master Beneficiary Summary File for the Medicare claims data. Race and ethnicity data are displayed to capture potential disparities across groups in receipt of medications for opioid use disorder. Other race and ethnicity categories are excluded due to small numbers.
