Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (53.8%), travel and lodging and education — rather than concentrated in one kind of arrangement. Abiomed accounts for 64.8% of it on its own, with 18 other manufacturers making up the rest. Reporting peaked in 2022 at $1,056 and has fallen 73.1% since, to $284 in 2025. That places this record below the midpoint for vascular surgery clinicians in AL, where the typical reported total is $5,256.
Across 31 payments — averaging $55.44 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

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
$1,719 in reported general payments places this provider in the 20th 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 |

| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 34 | $216 |
Paid to pharmacies, not to this prescriber.
