Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 2 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Abbott accounts for 80.7% of it on its own, with 1 other manufacturer making up the rest. That places this record below the midpoint for dermatology clinicians in TX, where the typical reported total is $4,085.
Across 2 payments — averaging $25.55 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Abbott$41
- Biofrontera Inc.$10
What the payments were for
- Food & beverage$51100%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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 |
|---|---|---|
| Abbott | 1 | $41 |
| Biofrontera Inc. | 1 | $10 |
How this compares
$51 in reported general payments places this provider in the 5th percentile of 1,098 dermatology 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.
