$212,183

Medicare paid this office $212,183 for 330 people.

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

Procedures Medicare counted

Who their Medicare patients are

330 Original Medicare patients in 2024. Average age 74 · Under 65 11% · 85 and older 12% · Women 56% · Also on Medicaid 35% · Health risk score 2.42. Above the middle of the specialty; the typical vascular surgery clinician is at 2.33.

Conditions among them: High blood pressure 75% · Chronic kidney disease 39% · Diabetes 38% · Coronary heart disease 37% · Heart failure 27% · Atrial fibrillation 25% · Depression 24% · COPD 17% · Stroke 15% · Cancer 11% · Dementia 6%.

The office billed $1,099,826, Medicare allowed $276,479 and paid $212,183; for 880 services of 77 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.

$1,620 in 2024

Medicaid paid $1,620 for 17 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.

$15,208

Pharmacies billed $15,208 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 22% of their Part D prescriptions (23 of 106) in 2024. Above the middle of the specialty; the typical vascular surgery clinician is at 11%.

93 generic and 13 brand-name prescriptions · $15,208 in drug cost.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.

$1,078 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.

6 measures · 2023

Medicare asked this office to report how often certain checkups happened in 2023. This is not a grade for the doctor. A specialist’s patients may not need every screening.
