Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (49.5%), speaking fees and consulting fees — rather than concentrated in one kind of arrangement. Abbott accounts for 64.1% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2020 at $1,600 and has fallen 73.5% since, to $424 in 2025. That places this record below the midpoint for thoracic surgery (cardiothoracic vascular surgery) clinicians in TN, where the typical reported total is $4,482.

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 |
|---|---|---|
| Abbott | 10 | $2,666 |
| Xvivo Perfusion Inc. | 6 | $1,112 |
| Abiomed | 2 | $202 |
| Siemens Medical Solutions USA, Inc. | 1 | $116 |
| Artivion, Inc. | 2 | $40 |
| Medtronic | 1 | $23 |
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
$4,159 in reported general payments places this provider in the 45th percentile of 115 thoracic surgery (cardiothoracic vascular surgery) providers in Tennessee.

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 |
|---|---|---|
| Rosuvastatin Calcium | 11 | $183 |
| Mupirocin | 11 | $69 |
Paid to pharmacies, not to this prescriber.
