Medicaid work
$289 in 2019
Medicaid paid $289 for 21 billed services this clinician did in 2019, 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
$19,633
Pharmacies billed $19,633 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 11% of their Part D prescriptions (22 of 201) in 2024. A higher opioid share than 9 in 10 peers; the typical hospitalist clinician is at 4%.
167 generic and fewer than 11 brand-name prescriptions · $19,633 in drug cost · 37 antibiotic prescriptions to 30 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.
