Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 11 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 10 manufacturers, the largest accounting for just 21.5% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $83 and has fallen 83.4% since, to $14 in 2025. That places this record below the midpoint for gastroenterology clinicians in NC, where the typical reported total is $1,694.
Across 11 payments — averaging $15.86 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Who reported the general payments

| Company | Payments | Total |
|---|---|---|
| Merck | 2 | $38 |
| AbbVie | 1 | $22 |
| Salix Pharmaceuticals, A Division Of Bausch Health US, LLC | 1 | $17 |
| Intercept Pharmaceuticals, Inc. | 1 | $17 |

How this compares
$174 in reported general payments places this provider in the 15th percentile of 610 gastroenterology providers in North Carolina.
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 | 14 | $2,381 |
| Pantoprazole Sodium | 151 | $1,456 |
| Famotidine | 41 | $546 |
| Omeprazole | 16 | $451 |
| Mercaptopurine | 12 | $212 |
