$111,569

Medicare paid this office $111,569 for 288 people.

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

Procedures Medicare counted

Who their Medicare patients are

288 Original Medicare patients in 2024. Average age 73 · Women 78% · Also on Medicaid 10% · Health risk score 0.84. At or below the middle of the specialty; the typical gastroenterology clinician is at 1.42.

Conditions among them: High blood pressure 68% · Diabetes 28% · Coronary heart disease 26% · Cancer 18% · Depression 17% · Atrial fibrillation 13% · Chronic kidney disease 10% · COPD 10% · Heart failure 8% · Stroke 7%.

The office billed $607,620, Medicare allowed $142,595 and paid $111,569; for 1,620 services of 28 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.

$0 in 2022

Medicaid paid $0 for 55 billed services this clinician did in 2022, up to 14 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.

$440,676

Pharmacies billed $440,676 in 2024.

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

457 generic and 167 brand-name prescriptions · $440,676 in drug cost · 45 antibiotic prescriptions to 31 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.

$8,391 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.

2 measures · 2023

Medicare asked this office to report how often certain checkups happened in 2023. This is not a grade for the doctor. A specialist’s patients may not need every screening.
