Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $154,162 of the $200,442 with a category attached, or 76.9%. Spineart SA accounts for 76.9% of it on its own, with 13 other manufacturers making up the rest. 2025 is the largest year on record at $41,045, 2.8 times the $14,686 reported in 2019. 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 109 payments — averaging $1838.92 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

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.
