Medicaid work

$425 in 2018

Medicaid paid $425 for 13 billed services this clinician did in 2018, up to 12 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

$517

Pharmacies billed $517 in 2024.

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

Opioids were 47% of their Part D prescriptions (42 of 90) in 2024. A higher opioid share than 9 in 10 peers; the typical physician assistant clinician is at 1%.

90 generic and 0 brand-name prescriptions · $517 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.
