Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (53.9%), travel and lodging and education — rather than concentrated in one kind of arrangement. 8 manufacturers reported payments, led by Medtronic at 40.2% of the total. That places this record below the midpoint for interventional cardiology clinicians in CT, where the typical reported total is $5,446.
Across 47 payments — averaging $100.50 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 |
|---|---|---|
| Medtronic | 26 | $1,898 |
| Boston Scientific | 5 | $1,315 |
| Abbott | 7 | $503 |
| Cardiovascular Systems Inc. | 2 | $315 |
| ZOLL Services LLC (a/k/a ZOLL Lifecor Corp) | 4 | $265 |
| Inari Medical, Inc. | 1 | $189 |
| Penumbra, Inc. | 1 | $139 |
| GE HealthCare | 1 | $100 |
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
$4,724 in reported general payments places this provider in the 40th percentile of 73 interventional cardiology providers in Connecticut.

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.
