Medicaid work
$0 in 2024
Medicaid paid $0 for 16 billed services this clinician did in 2024, up to 15 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
$2,104
Pharmacies billed $2,104 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
177 generic and fewer than 11 brand-name prescriptions · $2,104 in drug cost · 60 antibiotic prescriptions to 52 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.
