Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $41,500 of the $57,849 with a category attached, or 71.7%. Silk Road Medical, Inc. accounts for 71.6% of it on its own, with 24 other manufacturers making up the rest. Reporting peaked in 2019 at $20,120 and has fallen 97.0% since, to $613 in 2025. Among vascular surgery clinicians in LA 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.

General payments by program year
Who reported the general payments

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
$57,849 in reported general payments places this provider in the 95th percentile of 65 vascular surgery providers in Louisiana.
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 |
|---|---|---|
| XareltoRivaroxaban | 78 | $59,306 |
| EliquisApixaban | 70 | $49,613 |
| ClopidogrelClopidogrel Bisulfate | 143 | $816 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 100 | $415 |
| Gabapentin | 32 | $350 |
| Warfarin Sodium | 17 | $161 |
| Tramadol Hcl | 17 | $40 |
| Lorazepam | 21 | $26 |
Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| Johnson & JohnsonXarelto | $287 | $59,30678 claims |
| PfizerEliquis | $68 | $49,61370 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 65 vascular surgery providers in Louisiana.
