Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 16 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 8 manufacturers reported payments, led by Madrigal Pharmaceuticals at 24.6% of the total. 2025 is the largest year on record at $322, 2.6 times the $125 reported in 2022. That places this record below the midpoint for transplant surgery clinicians in TX, where the typical reported total is $2,154.
Across 16 payments — averaging $32.00 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Who reported the general payments

How this compares
$512 in reported general payments places this provider in the 25th percentile of 70 transplant surgery 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Omeprazole | 18 | $80 |
| Sulfamethoxazole-TrimethoprimSulfamethoxazole/Trimethoprim | 11 | $38 |
