Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

Medicaid work

$2,940 in 2024

Medicaid paid $2,940 for 26 billed services this clinician did in 2024, up to 13 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

$8,911

Pharmacies billed $8,911 in 2024.

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

Opioids were 24% of their Part D prescriptions (28 of 117) in 2024. A higher opioid share than 9 in 10 peers; the typical podiatry clinician is at 5%.

93 generic and 24 brand-name prescriptions · $8,911 in drug cost · 34 antibiotic prescriptions to 28 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.
