Payments from drug & device makers
What this record shows
This record is dominated by other: $150,667 of the $220,696 with a category attached, or 68.3%. Omnia Medical, LLC accounts for 96.6% of it on its own, with 12 other manufacturers making up the rest. Reporting peaked in 2024 at $81,101 and has fallen 89.2% since, to $8,792 in 2025. Among neurological surgery clinicians in OH 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 38 payments — averaging $5807.79 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$220,696 in reported general payments places this provider in the 95th percentile of 301 neurological surgery providers in Ohio.
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.
