Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $900 of the $900 with a category attached, or 100.0%. Every reported general payment came from a single manufacturer, Bayer. That places this record below the midpoint for medical oncology clinicians in MA, where the typical reported total is $2,567.
Across 1 payment — averaging $900.00 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Bayer$900
Across 28 payments — averaging $78,741 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 |
|---|---|---|
| Bayer | 1 | $900 |
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.
- Stivarga$900
