Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,436 of the $2,845 with a category attached, or 85.6%. Stryker accounts for 62.5% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2023 at $780 and has fallen 73.2% since, to $209 in 2025. That places this record below the midpoint for orthopaedic surgery clinicians in AZ, where the typical reported total is $4,792.
Across 42 payments — averaging $67.75 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 |
|---|---|---|
| Stryker | 22 | $1,778 |
| Intuitive Surgical | 7 | $518 |
| Davol Inc. | 6 | $417 |
| Orthofix Medical, Inc. | 3 | $60 |
| Novo Nordisk | 1 | $28 |
| Team_makena_llc | 2 | $22 |
| Smith+Nephew | 1 | $22 |
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.
- MAKO$931
- TRIATHLON$169
- Phasix Mesh$123
How this compares
$2,845 in reported general payments places this provider in the 40th percentile of 377 orthopaedic 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.
