$46,714

Medicare paid this office $46,714 for 230 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

230 Original Medicare patients in 2024. Average age 76 · Women 51% · Also on Medicaid 9% · Health risk score 1.56. Above the middle of the specialty; the typical anesthesiology clinician is at 1.54.

Conditions among them: High blood pressure 75% · Coronary heart disease 33% · Diabetes 28% · Atrial fibrillation 27% · Cancer 26% · Chronic kidney disease 25% · Heart failure 20% · Depression 18% · COPD 14% · Stroke 12% · Dementia 7%.

The office billed $429,564, Medicare allowed $60,411 and paid $46,714; for 285 services of 59 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.

$4,305 in 2021

Medicaid paid $4,305 for 62 billed services this clinician did in 2021, up to 15 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.

$42 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.
