$66,977

Medicare paid this office $66,977 for 2,496 people.

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

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

2,496 Original Medicare patients in 2024. Average age 74 · Under 65 9% · 85 and older 12% · Women 60% · Also on Medicaid 21% · Health risk score 1.50. At or below the middle of the specialty; the typical diagnostic radiology clinician is at 1.7.

The office billed $827,547, Medicare allowed $87,072 and paid $66,977; for 3,474 services of 106 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.

$3,465 in 2024

Medicaid paid $3,465 for 477 billed services this clinician did in 2024, up to 38 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.

Medicare did not publish checkup rates for this clinician.
