Medicaid work
$17,717 in 2024
Medicaid paid $17,717 for 262 billed services this clinician did in 2024, up to 29 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
$3,930
Pharmacies billed $3,930 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 6% of their Part D prescriptions (15 of 234) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.
214 generic and fewer than 11 brand-name prescriptions · $3,930 in drug cost · 100 antibiotic prescriptions to 99 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.
