Medicaid work

$18,173 in 2022

Medicaid paid $18,173 for 297 billed services this clinician did in 2022, up to 39 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

$10,700

Pharmacies billed $10,700 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 208) in 2024. At or below the middle of the specialty; the typical physician assistant clinician is at 1%.

169 generic and fewer than 11 brand-name prescriptions · $10,700 in drug cost · 61 antibiotic prescriptions to 49 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.

Largest Part D drug costs
Fluticasone Propionate12$422$26
Cephalexin20$59$3
Azithromycin11$28$3
Paxlovid20$0$0
