$118,542

Medicare paid this office $118,542 for 360 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

360 Original Medicare patients in 2024. Average age 75 · Under 65 5% · 85 and older 14% · Women 51% · Also on Medicaid 20% · Health risk score 1.43. Above the middle of the specialty; the typical gastroenterology clinician is at 1.42.

Conditions among them: High blood pressure 75% · Diabetes 44% · Coronary heart disease 31% · Chronic kidney disease 28% · Atrial fibrillation 22% · Cancer 18% · Heart failure 17% · Depression 15% · COPD 11% · Stroke 9% · Dementia 8%.

The office billed $696,785, Medicare allowed $157,132 and paid $118,542; for 1,493 services of 40 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.

$183 in 2024

Medicaid paid $183 for 15 billed services this clinician did in 2024, 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.

$887,311

Pharmacies billed $887,311 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 1,787) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.

1,365 generic and fewer than 11 brand-name prescriptions · $887,311 in drug cost · 44 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.

$1,944 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.
