Medicaid work

$7,822 in 2021

Medicaid paid $7,822 for 132 billed services this clinician did in 2021, 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

$15,308

Pharmacies billed $15,308 in 2024.

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

Opioids were 9% of their Part D prescriptions (23 of 250) in 2024. Above the middle of the specialty; the typical hospitalist clinician is at 4%.

230 generic and 20 brand-name prescriptions · $15,308 in drug cost · 27 antibiotic prescriptions to 24 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.
