Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $485,250 of the $620,598 with a category attached, or 78.2%. Stryker accounts for 100.0% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2022 at $180,001 and has fallen 77.5% since, to $40,581 in 2025. Among orthopaedic surgery clinicians in FL 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 613 payments — averaging $1012.39 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Stryker$621K

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 | 612 | $620,529 |
| Si-bone, Inc. | 1 | $69 |
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
$620,598 in reported general payments places this provider in the 95th percentile of 1,263 orthopaedic surgery providers in Florida.
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.
