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

$97,717

Medicare paid this office $97,717 for 110 people.

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

Procedures Medicare counted

Who their Medicare patients are

110 Original Medicare patients in 2024. Average age 74 · Under 65 11% · 85 and older 21% · Women 47% · Also on Medicaid 29% · Health risk score 2.60. Sicker patients than 9 in 10 peers; the typical plastic and reconstructive surgery clinician is at 1.21.

Conditions among them: High blood pressure 75% · Chronic kidney disease 43% · Diabetes 38% · Coronary heart disease 35% · Heart failure 33% · Atrial fibrillation 33% · Cancer 25% · Depression 21% · COPD 20% · Dementia 15% · Stroke 13%.

The office billed $612,717, Medicare allowed $124,543 and paid $97,717; for 1,320 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.

$12,450 in 2024

Medicaid paid $12,450 for 128 billed services this clinician did in 2024, up to 17 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.

$633 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.

Medicare did not publish checkup rates for this clinician.
