These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

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

Procedures Medicare counted

Who their Medicare patients are

89 Original Medicare patients in 2024. Average age 72 · Women 33% · Also on Medicaid 23% · Health risk score 1.48. At or below the middle of the specialty; the typical cardiac surgery clinician is at 1.73.

Conditions among them: High blood pressure 75% · Chronic kidney disease 75% · Atrial fibrillation 72% · Coronary heart disease 71% · Heart failure 69% · Diabetes 34% · Depression 22% · Stroke 17% · Cancer 15% · COPD 15%.

The office billed $2,146,868, Medicare allowed $324,181 and paid $258,473; for 228 services of 44 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.

$0 in 2020

Medicaid paid $0 for 32 billed services this clinician did in 2020, up to 13 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.

$30,000 in 2025

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.
