Procedures Medicare counted

Who their Medicare patients are

57 Original Medicare patients in 2024. Average age 73 · Women 53% · Also on Medicaid 19% · Health risk score 1.44. Above the middle of the specialty; the typical gastroenterology clinician is at 1.42.

Conditions among them: High blood pressure 61% · Cancer 37% · Diabetes 32% · Depression 25%.

The office billed $236,019, Medicare allowed $20,669 and paid $16,238; for 99 services of 16 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.

$121,172 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.
