What this record shows
This record is dominated by royalties or licence payments: $1,434,740 of the $1,472,975 with a category attached, or 97.4%. Microport Orthopedics Inc accounts for 99.5% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2019 at $609,231 and has fallen 98.1% since, to $11,345 in 2025. Among orthopaedic surgery clinicians in MI 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.

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.

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.
