Payments from drug & device makers

What this record shows

This record is dominated by royalties or licence payments: $134,951 of the $198,724 with a category attached, or 67.9%. Altus Partners. LLC accounts for 93.5% of it on its own, with 50 other manufacturers making up the rest. Reporting peaked in 2021 at $52,669 and has fallen 85.2% since, to $7,780 in 2024. Among neurological surgery clinicians in FL 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.

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

$198,724 in reported general payments places this provider in the 90th percentile of 556 neurological surgery providers in Florida.

Medicare billing

Part B allowed, 2024
$80,369
Medicare patients
84
Services billed
187

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.
