$82,582

Medicare paid this office $82,582 for 114 people. Most of that is long return visits and Botox.

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

Who their Medicare patients are

114 Original Medicare patients in 2024. Average age 70 · Women 47% · Also on Medicaid 23% · Health risk score 2.05. Above the middle of the specialty; the typical neurology clinician is at 1.61.

Conditions among them: High blood pressure 61% · Stroke 33% · Diabetes 30% · Depression 24% · Coronary heart disease 18% · Cancer 18% · Chronic kidney disease 17% · Atrial fibrillation 16% · Heart failure 15% · Dementia 13% · COPD 11%.

The office billed $376,220, Medicare allowed $104,249 and paid $82,582; for 1,119 services of 11 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.

$2,181 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.
