Medicaid work

$22,504 in 2023

Medicaid paid $22,504 for 511 billed services this clinician did in 2023, up to 63 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

$5,115

Pharmacies billed $5,115 in 2024.

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

288 generic and fewer than 11 brand-name prescriptions · $5,115 in drug cost · 160 antibiotic prescriptions to 130 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.
