This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

Who their Medicare patients are

The office billed $1,109,220, Medicare allowed $143,709 and paid $110,868; for 937 services of 51 kinds.

Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

Year by year

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.

$7,965 in 2024

Medicaid paid $7,965 for 224 billed services this clinician did in 2024, up to 22 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.

$448 in 2025

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.
