Medicaid work
$60 in 2023
Medicaid paid $60 for 123 billed services this clinician did in 2023, up to 38 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
$1,080
Pharmacies billed $1,080 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 27% of their Part D prescriptions (34 of 124) in 2024. Above the middle of the specialty; the typical physician assistant clinician is at 1%.
123 generic and fewer than 11 brand-name prescriptions · $1,080 in drug cost · 12 antibiotic prescriptions.
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.
| Meloxicam | 39 | $249 | $6 |
| Oxycodone | 26 | $136 | $5 |
| Amoxicillin | 11 | $89 | $8 |
