$17,117

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

Who their Medicare patients are

547 Original Medicare patients in 2024. Average age 76 · Under 65 7% · 85 and older 20% · Women 58% · Also on Medicaid 30% · Health risk score 2.00. Above the middle of the specialty; the typical diagnostic radiology clinician is at 1.7.

Conditions among them: High blood pressure 75% · Chronic kidney disease 48% · Coronary heart disease 40% · Diabetes 34% · Depression 32% · Heart failure 31% · Atrial fibrillation 28% · COPD 24% · Cancer 22% · Dementia 20% · Stroke 17%.

The office billed $224,654, Medicare allowed $22,595 and paid $17,117; for 844 services of 72 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.

$3,215 in 2024

Medicaid paid $3,215 for 289 billed services this clinician did in 2024, up to 56 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.

$125 in 2019

A payment is not proof that care is biased.

Medicare did not publish checkup rates for this clinician.
