Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $477 of the $739 with a category attached, or 64.5%. Stryker accounts for 64.5% of it on its own, with 2 other manufacturers making up the rest. Reporting peaked in 2024 at $477 and has fallen 96.7% since, to $16 in 2025. That places this record below the midpoint for neurological surgery clinicians in MI, where the typical reported total is $2,563.
Across 6 payments — averaging $123.22 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 | 1 | $477 |
| Siemens Medical Solutions USA, Inc. | 1 | $151 |
| Medtronic | 4 | $112 |
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
$739 in reported general payments places this provider in the 30th percentile of 256 neurological surgery providers in Michigan.
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.
