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

$80,680

Medicare paid this office $80,680 for 241 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

241 Original Medicare patients in 2024. Average age 74 · Under 65 9% · 85 and older 16% · Women 41% · Also on Medicaid 26% · Health risk score 1.53. At or below the middle of the specialty; the typical general surgery clinician is at 1.69.

Conditions among them: High blood pressure 73% · Coronary heart disease 26% · Diabetes 24% · Cancer 23% · Depression 22% · Atrial fibrillation 21% · Heart failure 20% · Chronic kidney disease 20% · COPD 20% · Dementia 8% · Stroke 5%.

The office billed $298,450, Medicare allowed $106,877 and paid $80,680; for 576 services of 71 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.

$683 in 2020

Medicaid paid $683 for 12 billed services this clinician did in 2020, up to 12 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.

$2,460

Pharmacies billed $2,460 in 2024.

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

Opioids were 61% of their Part D prescriptions (89 of 146) in 2024. Above the middle of the specialty; the typical general surgery clinician is at 34%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

144 generic and fewer than 11 brand-name prescriptions · $2,460 in drug cost · 25 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.

$1,958 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.
