Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 36 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Endologix LLC accounts for 86.7% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2019 at $1,136 and has fallen 97.6% since, to $28 in 2025. That places this record below the midpoint for vascular surgery clinicians in AL, where the typical reported total is $5,256.
Across 36 payments — averaging $79.98 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| Endologix LLC | 27 | $2,496 |
| Cvrx, Inc. | 1 | $134 |
| Philips North America LLC | 2 | $134 |

| Stryker | 1 | $17 |
| Lemaitre Vascular, Inc. | 2 | $16 |

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.
- AFX$1,258
- Ovation$1,083
- Alto Abdominal Stent Graft System$272
- ALTO$193
- Barostim Neo System$134
- IGT Devices Und$123
How this compares
$2,879 in reported general payments places this provider in the 35th percentile of 61 vascular 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| ClopidogrelClopidogrel Bisulfate | 125 | $1,558 |
| Tramadol Hcl | 42 | $175 |
| Hydroxychloroquine Sulfate | 14 | $113 |
