Medicaid work
$40,550 in 2024
Medicaid paid $40,550 for 1,110 billed services this clinician did in 2024, up to 63 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
$1,127
Pharmacies billed $1,127 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their Part D prescriptions (0 of 46) in 2024. Too few prescriptions to compare fairly with other clinicians.
38 generic and fewer than 11 brand-name prescriptions · $1,127 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.
| Erythromycin | 15 | $244 | $14 |
