Procedures Medicare counted

Who their Medicare patients are

103 Original Medicare patients in 2024. Average age 72 · Women 61% · Also on Medicaid 35% · Health risk score 2.18. Above the middle of the specialty; the typical plastic and reconstructive surgery clinician is at 1.21.

Conditions among them: High blood pressure 72% · Chronic kidney disease 32% · Depression 30% · Diabetes 29% · Coronary heart disease 27% · Cancer 26% · Atrial fibrillation 21% · Heart failure 20% · COPD 13% · Stroke 12%.

The office billed $292,962, Medicare allowed $44,536 and paid $34,488; for 295 services of 30 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.

$1,549 in 2024

Medicaid paid $1,549 for 26 billed services this clinician did in 2024, 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.

$31 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.
