Medicaid work

$1,505 in 2024

Medicaid paid $1,505 for 76 billed services this clinician did in 2024, up to 20 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

$122,385

Pharmacies billed $122,385 in 2024.

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

Opioids were 2% of their Part D prescriptions (38 of 2,296) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.

2,048 generic and 234 brand-name prescriptions · $122,385 in drug cost · 54 antibiotic prescriptions to 43 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.
