Medicaid work
$673 in 2023
Medicaid paid $673 for 24 billed services this clinician did in 2023, up to 12 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.

Pharmacies billed $4,546 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
172 generic and 34 brand-name prescriptions · $4,546 in drug cost · 104 antibiotic prescriptions to 94 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.
