Medicaid work

$221 in 2023

Medicaid paid $221 for 15 billed services this clinician did in 2023, up to 14 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

$775,271

Pharmacies billed $775,271 in 2024.

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

Opioids were 2% of their Part D prescriptions (11 of 642) in 2024. At or below the middle of the specialty; the typical medical oncology clinician is at 6%.

544 generic and fewer than 11 brand-name prescriptions · $775,271 in drug cost · 17 antibiotic prescriptions to 13 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.
