Medicaid work
$2,140 in 2021
Medicaid paid $2,140 for 59 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
$58,790
Pharmacies billed $58,790 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
664 generic and fewer than 11 brand-name prescriptions · $58,790 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.
