Medicaid work

$117 in 2023

Medicaid paid $117 for 12 billed services this clinician did in 2023, 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

$11,906

Pharmacies billed $11,906 in 2024.

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

Opioids were 4% of their Part D prescriptions (25 of 576) in 2024. Above the middle of the specialty; the typical family practice clinician is at 2%.

503 generic and fewer than 11 brand-name prescriptions · $11,906 in drug cost · 160 antibiotic prescriptions to 138 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.
