Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (46.1%), royalties or licence payments and speaking fees — rather than concentrated in one kind of arrangement. Smith+Nephew accounts for 62.7% of it on its own, with 8 other manufacturers making up the rest. 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.
Across 563 payments — averaging $2614.70 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Stryker$547K

Across 51 payments — averaging $3526.48 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

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
$1,472,076 in reported general payments places this provider in the 95th percentile of 829 orthopaedic 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Amoxicillin | 143 | $137 |
| Clindamycin Hcl | 44 | $49 |
