Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (54.9%), consulting fees and food and beverage — rather than concentrated in one kind of arrangement. 16 manufacturers reported payments, led by Boston Scientific at 55.4% of the total. Among gastroenterology clinicians in MD with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 104 payments — averaging $575.18 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$59,819 in reported general payments places this provider in the 90th percentile of 455 gastroenterology providers in Maryland.
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 |
|---|---|---|
| Famotidine | 79 | $1,575 |
| Omeprazole | 64 | $1,373 |
| Esomeprazole Magnesium | 21 | $1,107 |
| Peg 3350-ElectrolyteSodium Chloride/Nahco3/Kcl/Peg | 43 | $842 |
