Medicaid work

$458 in 2022

Medicaid paid $458 for 13 billed services this clinician did in 2022, up to 12 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

$691,289

Pharmacies billed $691,289 in 2024.

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

Opioids were 2% of their Part D prescriptions (24 of 1,016) in 2024. At or below the middle of the specialty; the typical rheumatology clinician is at 3%.

921 generic and 95 brand-name prescriptions · $691,289 in drug cost.

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.
