Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.8% of the total across 58 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 24 manufacturers, the largest accounting for just 17.4% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $311, 2.4 times the $132 reported in 2019. That places this record below the midpoint for orthopaedic surgery clinicians in LA, where the typical reported total is $3,274.
Across 58 payments — averaging $24.94 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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
$1,447 in reported general payments places this provider in the 35th percentile of 286 orthopaedic surgery 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.
