Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $3,764,874 of the $3,833,927 with a category attached, or 98.2%. Globus Medical accounts for 96.9% of it on its own, with 15 other manufacturers making up the rest. 2025 is the largest year on record at $1,059,837, more than ten times the $28,106 reported in 2019. Among orthopaedic surgery clinicians in GA 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 266 payments — averaging $14,413 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$3,833,927 in reported general payments places this provider in the 95th percentile of 654 orthopaedic surgery providers in Georgia.
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.
