Medicaid work
$68,545 in 2024
Medicaid paid $68,545 for 470 billed services this clinician did in 2024, up to 33 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
$5,970
Pharmacies billed $5,970 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 7% of their Part D prescriptions (21 of 292) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.
277 generic and 15 brand-name prescriptions · $5,970 in drug cost · 77 antibiotic prescriptions to 64 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.
