$181,316

Medicare paid this office $181,316 for 625 people.

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

Who their Medicare patients are

625 Original Medicare patients in 2024. Average age 72 · Under 65 7% · 85 and older 3% · Women 48% · Also on Medicaid 9% · Health risk score 1.20. At or below the middle of the specialty; the typical neurology clinician is at 1.61.

Conditions among them: High blood pressure 75% · Diabetes 40% · Coronary heart disease 38% · Depression 37% · Chronic kidney disease 27% · COPD 20% · Cancer 16% · Atrial fibrillation 16% · Heart failure 15% · Stroke 15% · Dementia 7%.

The office billed $2,628,799, Medicare allowed $227,714 and paid $181,316; for 4,463 services of 19 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.

$2,795 in 2024

Medicaid paid $2,795 for 93 billed services this clinician did in 2024, up to 14 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 2024

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

A payment is not proof that care is biased.
