Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 93.7% of the total across 410 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 23 manufacturers reported payments, led by Gilead at 34.5% of the total. Among gerontology clinicians in TX with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 410 payments — averaging $20.96 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Gilead$3K
- Viiv Healthcare Company$2K
- Napo Pharmaceuticals Inc$630
- Johnson & Johnson$624
- Merck$620
- Antares Pharma, Inc.$190
- plus $1K from 17 others
Across 9 payments — averaging $151.84 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.
- AbbVie$1K
What the payments were for
- Speaking & faculty fees$3885%
- Food & beverage$8,05794%
- Education$1502%
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.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| GileadBiktarvy, Descovy | $2,966 | $284,69980 claims |
| Johnson & JohnsonPrezcobix | $624 | $32,08413 claims |
| MerckIsentress Hd | $620 | $28,10514 claims |
| Novo NordiskOzempic | $182 | $19,39619 claims |
| Lilly USA, LLCMounjaro | $88 | $14,93914 claims |
| Antares Pharma, Inc.Xyosted | $190 | $7,74012 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 653 gerontology providers in Texas.
