Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 91.7% of the total across 10 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 7 manufacturers reported payments, led by AbbVie at 44.0% of the total. 2025 is the largest year on record at $119, 2.1 times the $56 reported in 2019. That places this record below the midpoint for gastroenterology clinicians in MA, where the typical reported total is $854.
Across 10 payments — averaging $36.44 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- AbbVie$160
- Takeda Pharmaceuticals U.S.A., Inc.$91
- Salix Pharmaceuticals, A Division Of Bausch Health US, LLC$32
- Pfizer$30

- plus $15 from 1 others
Across 5 payments — averaging $885.00 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.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |

| Takeda Pharmaceuticals U.S.A., Inc. | 1 | $91 |
| Salix Pharmaceuticals, A Division Of Bausch Health US, LLC | 2 | $32 |

| Gilead | 1 | $15 |
How this compares
$364 in reported general payments places this provider in the 35th percentile of 579 gastroenterology providers in Massachusetts.
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

| Sod Sulf-Potass Sulf-Mag SulfSodium, Potassium,mag Sulfates | 158 | $11,374 |
