Medicaid work

$829 in 2021

Medicaid paid $829 for 65 billed services this clinician did in 2021, up to 17 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

$98,468

Pharmacies billed $98,468 in 2024.

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

1,236 generic and fewer than 11 brand-name prescriptions · $98,468 in drug cost · 47 antibiotic prescriptions to 45 people.

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.
