$2,133 in 2022
Medicaid paid $2,133 for 47 billed services this clinician did in 2022, 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 $3,783 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
96 generic and fewer than 11 brand-name prescriptions · $3,783 in drug cost · 17 antibiotic prescriptions to 14 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.
