Medicaid work
$2,135 in 2022
Medicaid paid $2,135 for 25 billed services this clinician did in 2022, up to 13 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
$12,781
Pharmacies billed $12,781 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
86 generic and fewer than 11 brand-name prescriptions · $12,781 in drug cost · 31 antibiotic prescriptions to 27 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.
