Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 32 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. THD America, Inc. accounts for 69.9% of it on its own, with 9 other manufacturers making up the rest. Reporting peaked in 2023 at $566 and has fallen 50.1% since, to $282 in 2025. That places this record below the midpoint for colon & rectal surgery clinicians in GA, where the typical reported total is $4,045.
Across 32 payments — averaging $60.05 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 |
|---|---|---|
| THD America, Inc. | 17 | $1,343 |
| Intuitive Surgical | 3 | $224 |
| Baxter Healthcare | 2 | $144 |
| Medtronic | 4 | $100 |
| Johnson & Johnson | 1 | $36 |
| Takeda Pharmaceuticals U.S.A., Inc. | 1 | $22 |
| Braintree Laboratories, Inc. | 1 | $20 |
| Shire North American Group Inc | 1 | $11 |
| Olympus America Inc. | 1 | $11 |
| Prescient Surgical | 1 | $11 |
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
$1,922 in reported general payments places this provider in the 30th percentile of 66 colon & rectal surgery providers in Georgia.
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
