Medicaid work

$3,444 in 2024

Medicaid paid $3,444 for 28 billed services this clinician did in 2024, up to 14 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

$149

Pharmacies billed $149 in 2024.

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

Opioids were 77% of their Part D prescriptions (39 of 51) in 2024. A higher opioid share than 9 in 10 peers; the typical general surgery clinician is at 34%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

51 generic and 0 brand-name prescriptions · $149 in drug cost.

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.
