Medicaid work
$20,531 in 2024
Medicaid paid $20,531 for 311 billed services this clinician did in 2024, up to 23 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
$6,629
Pharmacies billed $6,629 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 7% of their Part D prescriptions (16 of 244) in 2024. At or below the middle of the specialty; the typical emergency medicine clinician is at 12%.
215 generic and fewer than 11 brand-name prescriptions · $6,629 in drug cost · 112 antibiotic prescriptions to 102 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.
