$73,215

Medicare paid this office $73,215 for 2,954 people.

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

Who their Medicare patients are

2,954 Original Medicare patients in 2024. Average age 74 · Under 65 11% · 85 and older 16% · Women 52% · Also on Medicaid 28% · Health risk score 2.35. Above the middle of the specialty; the typical diagnostic radiology clinician is at 1.7.

The office billed $1,069,545, Medicare allowed $95,776 and paid $73,215; for 4,873 services of 43 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.

$32,400 in 2024

Medicaid paid $32,400 for 3,021 billed services this clinician did in 2024, up to 196 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.

$83 in 2019

A payment is not proof that care is biased.
