Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 5 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Amgen accounts for 86.9% of it on its own, with 1 other manufacturer making up the rest. That places this record below the midpoint for neurological surgery clinicians in TX, where the typical reported total is $3,746.
Across 5 payments — averaging $60.10 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Amgen$261
- Alphatec Spine, Inc$39
Across 60 payments — averaging $11,985 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.
- Vivus LLC$370K
- Pfizer$268K
- Novartis$81K
What the payments were for
- Food & beverage$301100%
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.
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 |
|---|---|---|
| Amgen | 4 | $261 |
| Alphatec Spine, Inc | 1 | $39 |
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.
How this compares
$301 in reported general payments places this provider in the 10th percentile of 582 neurological surgery providers in Texas.
