$449,274

Medicare paid this office $449,274 for 710 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

710 Original Medicare patients in 2024. Average age 75 · Under 65 10% · 85 and older 17% · Women 54% · Also on Medicaid 35% · Health risk score 2.77. Above the middle of the specialty; the typical vascular surgery clinician is at 2.33.

Conditions among them: High blood pressure 75% · Diabetes 49% · Chronic kidney disease 44% · Coronary heart disease 39% · Heart failure 28% · Atrial fibrillation 28% · Depression 24% · COPD 18% · Stroke 15% · Cancer 14% · Dementia 10%.

The office billed $3,200,387, Medicare allowed $569,106 and paid $449,274; for 2,943 services of 127 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.

$8,629

Pharmacies billed $8,629 in 2024.

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

Opioids were 20% of their Part D prescriptions (25 of 125) 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.

115 generic and fewer than 11 brand-name prescriptions · $8,629 in drug cost · 23 antibiotic prescriptions to 18 people.

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.

$8,696 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.
