Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (54.1%), travel and lodging and speaking fees — rather than concentrated in one kind of arrangement. Intuitive Surgical accounts for 84.7% of it on its own, with 10 other manufacturers making up the rest. Reporting peaked in 2019 at $2,751 and has fallen 92.9% since, to $195 in 2025. That places this record below the midpoint for colon & rectal surgery clinicians in AZ, where the typical reported total is $5,787.
Across 70 payments — averaging $92.11 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.

| Braintree Laboratories, Inc. | 7 | $256 |
| Medtronic | 2 | $245 |

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.
- Da Vinci Surgical System$4,405
- LigaSure$175
- Signia$170
How this compares
$6,448 in reported general payments places this provider in the 50th percentile of 50 colon & rectal surgery providers in Arizona.
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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |

| Sod Sulf-Potass Sulf-Mag SulfSodium, Potassium,mag Sulfates | 128 | $8,481 |
| Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen | 16 | $254 |
