Medicaid work
$3,297 in 2024
Medicaid paid $3,297 for 370 billed services this clinician did in 2024, up to 39 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
$21,030
Pharmacies billed $21,030 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 29% of their Part D prescriptions (90 of 308) in 2024. At or below the middle of the specialty; the typical general surgery clinician is at 34%.
293 generic and 15 brand-name prescriptions · $21,030 in drug cost · 69 antibiotic prescriptions to 57 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.
