Medicaid work

$9,386 in 2024

Medicaid paid $9,386 for 562 billed services this clinician did in 2024, up to 28 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

$27,844

Pharmacies billed $27,844 in 2024.

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.
