What this record shows
This record is dominated by travel and lodging: $2,448 of the $3,332 with a category attached, or 73.4%. Si-bone, Inc. accounts for 76.8% of it on its own, with 10 other manufacturers making up the rest. 2025 is the largest year on record at $2,758, more than ten times the $113 reported in 2019. That places this record below the midpoint for neurological surgery clinicians in AL, where the typical reported total is $2,898.
Across 35 payments — averaging $95.21 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
- IFUSE IMPLANT SYSTEM$2,236
How this compares
$3,332 in reported general payments places this provider in the 50th percentile of 97 neurological surgery providers in Alabama.
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.
