What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 5 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 4 manufacturers reported payments, led by Organ Recovery Systems, Inc. at 45.4% of the total. That places this record below the midpoint for transplant surgery clinicians in NY, where the typical reported total is $1,271.

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.

|---|---|---|
| Organ Recovery Systems, Inc. | 1 | $327 |
| Medtronic | 2 | $185 |
| Albireo Pharma, Inc. | 1 | $130 |
| Regeneron | 1 | $77 |
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
$719 in reported general payments places this provider in the 40th percentile of 72 transplant surgery providers in New York.
