Medicaid work

$20,832 in 2024

Medicaid paid $20,832 for 419 billed services this clinician did in 2024, up to 49 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

$7,390

Pharmacies billed $7,390 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 10% of their Part D prescriptions (65 of 636) in 2024. Above the middle of the specialty; the typical podiatry clinician is at 5%.

633 generic and fewer than 11 brand-name prescriptions · $7,390 in drug cost · 64 antibiotic prescriptions to 42 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.
