Medicaid work

$4,192 in 2024

Medicaid paid $4,192 for 138 billed services this clinician did in 2024, up to 19 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

$896,248

Pharmacies billed $896,248 in 2024.

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

Opioids were 5% of their Part D prescriptions (28 of 583) in 2024. At or below the middle of the specialty; the typical medical oncology clinician is at 6%.

402 generic and 181 brand-name prescriptions · $896,248 in drug cost · 18 antibiotic prescriptions.

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.
