Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (59.2%), education and speaking fees — rather than concentrated in one kind of arrangement. 14 manufacturers reported payments, led by Olympus Corporation Of The Americas at 41.0% of the total. Among gastroenterology clinicians in PA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 211 payments — averaging $909.02 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$191,803 in reported general payments places this provider in the 95th percentile of 935 gastroenterology providers in Pennsylvania.
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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Mesalamine | 17 | $4,011 |
| Gavilyte-GPeg3350/Sod Sulf,bicarb,cl/Kcl | 49 | $857 |
| Peg-3350 And ElectrolytesPeg3350/Sod Sulf,bicarb,cl/Kcl | 29 | $515 |
