Medicaid work
$34,922 in 2024
Medicaid paid $34,922 for 687 billed services this clinician did in 2024, up to 44 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
$12,169
Pharmacies billed $12,169 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 18% of their Part D prescriptions (55 of 301) in 2024. Above the middle of the specialty; the typical emergency medicine clinician is at 12%.
287 generic and 14 brand-name prescriptions · $12,169 in drug cost · 69 antibiotic prescriptions to 66 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.
