Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 19 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 15 manufacturers, the largest accounting for just 20.8% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for nephrology clinicians in LA, where the typical reported total is $1,900.
Across 19 payments — averaging $33.63 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 |
|---|---|---|
| United Therapeutics Corporation | 1 | $133 |
| Calliditas Therapeutics US Inc. | 1 | $125 |
| Veloxis Pharmaceuticals, Inc. | 3 | $81 |
| Nxstage Medical, Inc. | 1 | $46 |
| ANI Pharmaceuticals, Inc. | 2 | $44 |
| Ipsen Biopharmaceuticals, Inc | 2 | $39 |
| Mallinckrodt Hospital Products Inc. | 1 | $35 |

| Novo Nordisk | 1 | $15 |

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.
- TARPEYO$125
How this compares
$639 in reported general payments places this provider in the 25th percentile of 206 nephrology 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.
