$43,447

Medicare paid this office $43,447 for 139 people. Most of that is long return visits and Botox.

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

Who their Medicare patients are

139 Original Medicare patients in 2024. Average age 73 · Women 60% · Also on Medicaid 34% · Health risk score 1.75. Above the middle of the specialty; the typical gastroenterology clinician is at 1.42.

Conditions among them: High blood pressure 75% · Diabetes 35% · Chronic kidney disease 32% · Coronary heart disease 29% · Depression 22% · Heart failure 19% · Cancer 18% · COPD 17% · Atrial fibrillation 15% · Stroke 8%.

The office billed $145,064, Medicare allowed $57,901 and paid $43,447; for 435 services of 15 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.

$68,139 in 2024

Medicaid paid $68,139 for 1,050 billed services this clinician did in 2024, up to 41 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.

$501,066

Pharmacies billed $501,066 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 468) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.

333 generic and 135 brand-name prescriptions · $501,066 in drug cost · 21 antibiotic prescriptions.

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.

$353,789 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.
