Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (52.4%), travel and lodging and entertainment — rather than concentrated in one kind of arrangement. 12 manufacturers reported payments, led by Zap Surgical Systems, Inc. at 50.0% of the total. Reporting peaked in 2021 at $564 and has fallen 72.3% since, to $156 in 2025. That places this record below the midpoint for neurological surgery clinicians in CO, where the typical reported total is $3,397.
Across 22 payments — averaging $55.42 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 |
|---|---|---|
| Zap Surgical Systems, Inc. | 4 | $610 |
| Boston Scientific | 2 | $141 |
| Penumbra, Inc. | 1 | $123 |
| Integra Lifesciences Corporation | 3 | $58 |
| Johnson & Johnson | 1 | $56 |
| Bristol Myers Squibb | 3 | $55 |
| GT Medical Technologies, Inc | 1 | $53 |

| Aesculap, Inc. | 1 | $18 |

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
$1,219 in reported general payments places this provider in the 30th percentile of 149 neurological surgery providers in Colorado.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
