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

$46,352

Medicare paid this office $46,352 for 92 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

92 Original Medicare patients in 2024. Average age 71 · Women 56% · Also on Medicaid 46% · Health risk score 2.23. Sicker patients than 9 in 10 peers; the typical colorectal surgery (proctology) clinician is at 1.44.

Conditions among them: High blood pressure 75% · Cancer 51% · Diabetes 37% · Chronic kidney disease 34% · Coronary heart disease 30% · Depression 29% · Atrial fibrillation 23% · Heart failure 17% · COPD 16%.

The office billed $379,834, Medicare allowed $58,599 and paid $46,352; for 185 services of 59 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.

$81 in 2019

Medicaid paid $81 for 16 billed services this clinician did in 2019, up to 16 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.

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

Opioids were 0% of their 26 Part D prescriptions in 2022. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

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

Year by year

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

$2,669 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.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.
