Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $115,250 of the $144,701 with a category attached, or 79.6%. Stryker accounts for 75.3% of it on its own, with 14 other manufacturers making up the rest. Reporting peaked in 2022 at $32,624 and has fallen 53.8% since, to $15,084 in 2025. Among neurological surgery clinicians in MD with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 252 payments — averaging $574.21 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares

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 |
|---|---|---|
| Mupirocin | 18 | $132 |
| Gabapentin | 12 | $65 |
Paid to pharmacies, not to this prescriber.
