Gastroenterology in Indiana

323 providers, $4,565,417 in total reported payments from drug and device makers. Ranked below by lifetime general payments. The median provider in this group received $2,225.

Ranking high here usually means a consulting or royalty arrangement, not wrongdoing. Payments to device inventors and trial investigators are legal, disclosed, and concentrated in a small number of people — which is exactly why a list like this has a steep top and a long flat tail.

What Medicare pays gastroenterology clinicians in Indiana

Part B allowed per clinician, 2024
$102,760

Clinicians billing Part B
265

Across 265 gastroenterology clinicians in Indiana who billed Original Medicare Part B in 2024, Medicare allowed $27,231,483 in total — an average of $102,760 each, of which $90,202 was for services and the rest for drugs administered in the office.

This is not a salary. The rest is what Medicare allowed for services these clinicians billed — Original Medicare fee-for-service only. It excludes Medicare Advantage, which now covers more than half of Medicare enrollees, along with Medicaid and every commercial insurer, so for most clinicians it is a fraction of their practice. It is also gross revenue: staff, rent, supplies and malpractice premiums all come out of it before anyone is paid. Anyone quoting a figure like this as physician pay is misreading it.
