Medicaid work
$376 in 2023
Medicaid paid $376 for 36 billed services this clinician did in 2023, up to 22 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
$897
Pharmacies billed $897 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 57) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.
47 generic and fewer than 11 brand-name prescriptions · $897 in drug cost · 28 antibiotic prescriptions to 24 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.
