Medicaid work
$1,051 in 2019
Medicaid paid $1,051 for 24 billed services this clinician did in 2019, up to 12 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
$32,402
Pharmacies billed $32,402 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 13% of their Part D prescriptions (50 of 394) in 2024. At or below the middle of the specialty; the typical pain management clinician is at 44%. Long-acting opioids: 30% of their opioid prescriptions.
373 generic and 21 brand-name prescriptions · $32,402 in drug cost.
Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.
