Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 70 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 19 manufacturers, the largest accounting for just 22.6% — the pattern of someone who eats at a lot of different presentations.
Across 70 payments — averaging $23.66 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Madrigal Pharmaceuticals$165
- AbbVie$133
- Phathom Pharmaceuticals, Inc.$127
- Sanofi$107
- Ardelyx, Inc.$103
- plus $646 from 13 others
Across 114 payments — averaging $3684.79 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

What the payments were for

How this compares
$1,656 in reported general payments places this provider in the 55th percentile of 787 gastroenterology providers in Illinois.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
