Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $62,017 of the $100,926 with a category attached, or 61.4%. 37 manufacturers reported payments, led by Johnson & Johnson at 53.6% of the total. 2025 is the largest year on record at $36,421, more than ten times the $2,816 reported in 2019. Among vascular surgery clinicians in SC 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.

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
$100,926 in reported general payments places this provider in the 90th percentile of 99 vascular surgery providers in South Carolina.
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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| EliquisApixaban | 22 | $12,534 |
| ClopidogrelClopidogrel Bisulfate | 57 | $542 |
| Cilostazol | 20 | $281 |
