Medicaid work

$351,642 in 2024

Medicaid paid $351,642 for 4,846 billed services this clinician did in 2024, up to 158 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

$261,572

Pharmacies billed $261,572 in 2024.

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

Opioids were 5% of their Part D prescriptions (89 of 1,995) in 2024. Above the middle of the specialty; the typical family practice clinician is at 2%.

1,703 generic and 273 brand-name prescriptions · $261,572 in drug cost · 27 antibiotic prescriptions to 17 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.
