Medicaid work

$20,925 in 2024

Medicaid paid $20,925 for 400 billed services this clinician did in 2024, up to 45 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

$315,504

Pharmacies billed $315,504 in 2024.

3,596 generic and 324 brand-name prescriptions · $315,504 in drug cost · 65 antibiotic prescriptions to 51 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.
