Medicaid work

$812 in 2024

Medicaid paid $812 for 20 billed services this clinician did in 2024, up to 18 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

$105,743

Pharmacies billed $105,743 in 2024.

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

Opioids were 1% of their Part D prescriptions (18 of 1,981) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

1,751 generic and 215 brand-name prescriptions · $105,743 in drug cost · 130 antibiotic prescriptions to 109 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.
