Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 95.5% of the total across 106 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 12 manufacturers reported payments, led by Organogenesis Inc. at 49.0% of the total. Reporting peaked in 2022 at $541 and has fallen 85.0% since, to $81 in 2025. Among emergency medicine clinicians in LA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 106 payments — averaging $18.64 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 |
|---|---|---|
| Organogenesis Inc. | 57 | $968 |
| AbbVie(2 entities) | 14 | $280 |
| Smith+Nephew | 14 | $194 |
| Kerecis Limited | 4 | $188 |
| Convatec Inc. | 7 | $126 |
| KCI USA, Inc. | 2 | $55 |
| Paratek Pharmaceuticals, Inc. | 2 | $45 |
| Reprise Biomedical, Inc. | 2 | $36 |
| Aroa Biosurgery Incorporated | 1 | $32 |
| Hartmann USA, Inc. | 1 | $19 |
| Lifenet Health | 1 | $17 |
| Polarityte, Inc. | 1 | $14 |
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
$1,976 in reported general payments places this provider in the 95th percentile of 881 emergency medicine 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Doxycycline Monohydrate | 40 | $319 |
| Amoxicillin-Clavulanate PotassAmoxicillin/Potassium Clav | 18 | $236 |
| Gabapentin | 16 | $141 |
| Ciprofloxacin Hcl | 17 | $119 |
| Triamcinolone Acetonide | 15 | $104 |
| Doxycycline Hyclate | 19 | $94 |
| Cephalexin | 11 | $72 |
