$428,658

Medicare paid this office $428,658 for 814 people.

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

Procedures Medicare counted

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

814 Original Medicare patients in 2024. Average age 76 · Under 65 6% · 85 and older 16% · Women 44% · Also on Medicaid 25% · Health risk score 2.08. At or below the middle of the specialty; the typical vascular surgery clinician is at 2.33.

Conditions among them: High blood pressure 75% · Coronary heart disease 46% · Diabetes 43% · Chronic kidney disease 41% · Atrial fibrillation 29% · Heart failure 27% · COPD 21% · Depression 19% · Cancer 17% · Stroke 17% · Dementia 7%.

The office billed $1,824,609, Medicare allowed $552,576 and paid $428,658; for 3,080 services of 130 kinds; $173 of it was for drugs given in the office and $428,485 for care.

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.

$16,538 in 2024

Medicaid paid $16,538 for 80 billed services this clinician did in 2024, up to 15 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.

$42,545

Pharmacies billed $42,545 in 2024.

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

Opioids were 11% of their Part D prescriptions (16 of 140) in 2024. Above the middle of the specialty; the typical vascular surgery clinician is at 11%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

108 generic and 32 brand-name prescriptions · $42,545 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.

$877 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.
