Medicaid paid $30,895 for 1,010 billed services this clinician did in 2024, up to 41 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
$1,442
Pharmacies billed $1,442 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 16% of their Part D prescriptions (21 of 129) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.
125 generic and fewer than 11 brand-name prescriptions · $1,442 in drug cost · 44 antibiotic prescriptions to 40 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.
