Medicaid work
$616,002 in 2024
Medicaid paid $616,002 for 3,943 billed services this clinician did in 2024, up to 159 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
$7,047
Pharmacies billed $7,047 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
252 generic and fewer than 11 brand-name prescriptions · $7,047 in drug cost · 24 antibiotic prescriptions to 18 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.
