Medicaid work
$12 in 2021
Medicaid paid $12 for 50 billed services this clinician did in 2021, up to 18 people in a month for one service.
Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

Drugs they prescribed that Part D paid
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their 21 Part D prescriptions in 2023. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
