$22,319

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

Procedures Medicare counted

Who their Medicare patients are

99 Original Medicare patients in 2024. Average age 72 · Under 65 16% · 85 and older 13% · Women 61% · Also on Medicaid 30% · Health risk score 1.16. At or below the middle of the specialty; the typical gastroenterology clinician is at 1.42.

Conditions among them: High blood pressure 71% · Diabetes 28% · Depression 22% · Coronary heart disease 21% · Chronic kidney disease 21% · Cancer 20% · Atrial fibrillation 19% · Heart failure 15% · COPD 12% · Stroke 11%.

The office billed $171,174, Medicare allowed $28,327 and paid $22,319; for 171 services of 21 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.

$906 in 2023

Medicaid paid $906 for 16 billed services this clinician did in 2023, up to 13 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.

$5,086

Pharmacies billed $5,086 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 81) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.

68 generic and 13 brand-name prescriptions · $5,086 in drug cost.

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.

$112 in 2024

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.
