Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 1 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Every reported general payment came from a single manufacturer, Novartis. That places this record below the midpoint for pediatric hematology-oncology clinicians in TX, where the typical reported total is $348.
Across 1 payment — averaging $125.36 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Novartis$125
Across 88 payments — averaging $10,564 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.

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 |
|---|---|---|
| Novartis | 1 | $125 |
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.
