Medicaid work
$11,040 in 2024
Medicaid paid $11,040 for 135 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
$187,566
Pharmacies billed $187,566 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 2% of their Part D prescriptions (55 of 3,305) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.
3,004 generic and 280 brand-name prescriptions · $187,566 in drug cost · 67 antibiotic prescriptions to 50 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.
