Medicaid work

$50,525 in 2024

Medicaid paid $50,525 for 2,105 billed services this clinician did in 2024, up to 293 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

$21,597

Pharmacies billed $21,597 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

372 generic and 45 brand-name prescriptions · $21,597 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.
