Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $262,566 of the $381,131 with a category attached, or 68.9%. Every reported general payment came from a single manufacturer, Medtronic. Among neurological surgery clinicians in UT 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 265 payments — averaging $1438.23 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| Medtronic(2 entities) | 265 | $381,131 |
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
$381,131 in reported general payments places this provider in the 95th percentile of 75 neurological surgery providers in Utah.
