Medicaid work
$1,352 in 2024
Medicaid paid $1,352 for 16 billed services this clinician did in 2024, up to 15 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
$4,251
Pharmacies billed $4,251 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 39% of their Part D prescriptions (117 of 303) in 2024. Above the middle of the specialty; the typical orthopedic surgery clinician is at 31%.
285 generic and 18 brand-name prescriptions · $4,251 in drug cost · 29 antibiotic prescriptions to 18 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.

Research money
Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.
