Medicaid work

$284 in 2020

Medicaid paid $284 for 34 billed services this clinician did in 2020, up to 22 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

$2,101

Pharmacies billed $2,101 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 24% of their Part D prescriptions (57 of 235) in 2024. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 31%.

234 generic and fewer than 11 brand-name prescriptions · $2,101 in drug cost · 30 antibiotic prescriptions to 25 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.

A payment is not proof that care is biased.
