$73,162

Medicare paid this office $73,162 for 766 people.

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

Who their Medicare patients are

766 Original Medicare patients in 2024. Average age 76 · Under 65 9% · 85 and older 23% · Women 55% · Also on Medicaid 34% · Health risk score 2.31. Above the middle of the specialty; the typical diagnostic radiology clinician is at 1.7.

Conditions among them: High blood pressure 75% · Coronary heart disease 43% · Chronic kidney disease 42% · Diabetes 38% · Stroke 38% · Atrial fibrillation 35% · Heart failure 34% · Depression 33% · Dementia 31% · Cancer 23% · COPD 21%.

The office billed $1,043,845, Medicare allowed $93,196 and paid $73,162; for 1,375 services of 33 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.

$22,101 in 2024

Medicaid paid $22,101 for 472 billed services this clinician did in 2024, up to 63 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.

$141 in 2024

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

A payment is not proof that care is biased.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.

Medicare did not publish checkup rates for this clinician.
