Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 49 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. AbbVie accounts for 86.5% of it on its own, with 4 other manufacturers making up the rest. 2025 is the largest year on record at $296, 5.0 times the $59 reported in 2019. That places this record below the midpoint for transplant hepatology clinicians in TX, where the typical reported total is $5,913.
Across 49 payments — averaging $20.03 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| AbbVie | 45 | $849 |
| Novo Nordisk | 1 | $59 |
| Orphalan Inc | 1 | $40 |
| Takeda Pharmaceuticals U.S.A., Inc. | 1 | $18 |
| Nestle Healthcare Nutrition Inc. | 1 | $16 |
How this compares
$982 in reported general payments places this provider in the 20th percentile of 28 transplant hepatology providers in Texas.
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.
