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 |
|---|---|---|
| Trimed, Inc. | 2 | $1,137 |
| Crossroads Extremity Systems, LLC | 1 | $952 |
| Musculoskeletal Transplant Foundation Inc. | 2 | $474 |
| Treace Medical Concepts, Inc. | 4 | $133 |
| Stryker(2 entities) | 2 | $119 |
| Smith+Nephew | 5 | $95 |
| Evolution Surgical, Inc | 1 | $22 |
| Amgen | 1 | $12 |
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
$2,943 in reported general payments places this provider in the 55th percentile of 1,126 foot & ankle surgery providers in California.
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.
