$116,179

Medicare paid this office $116,179 for 310 people.

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

Procedures Medicare counted

Who their Medicare patients are

310 Original Medicare patients in 2024. Average age 74 · Women 46% · Also on Medicaid 5% · Health risk score 0.98. At or below the middle of the specialty; the typical colorectal surgery (proctology) clinician is at 1.44.

Conditions among them: High blood pressure 65% · Coronary heart disease 23% · Cancer 23% · Diabetes 20% · Atrial fibrillation 16% · Chronic kidney disease 13% · Depression 10% · Heart failure 7% · Stroke 6% · COPD 5% · Dementia 5%.

The office billed $796,986, Medicare allowed $150,554 and paid $116,179; for 692 services of 56 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.

$11,987

Pharmacies billed $11,987 in 2024.

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

Opioids were 11% of their Part D prescriptions (19 of 179) in 2024. At or below the middle of the specialty; the typical colorectal surgery (proctology) clinician is at 16%.

125 generic and 54 brand-name prescriptions · $11,987 in drug cost · 51 antibiotic prescriptions to 21 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.

$284 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.
