Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $52,530 of the $62,940 with a category attached, or 83.5%. E.r. Squibb & Sons, L.L.C. accounts for 63.9% of it on its own, with 5 other manufacturers making up the rest. 2025 is the largest year on record at $25,270, more than ten times the $433 reported in 2019. Among cardiovascular disease clinicians in MA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 21 payments — averaging $2997.13 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 |
|---|---|---|
| E.r. Squibb & Sons, L.L.C. | 12 | $40,196 |
| Lexicon Pharmaceuticals, Inc. | 3 | $12,298 |
| AstraZeneca | 2 | $3,850 |
| Astrazeneca UK Limited | 1 | $3,222 |
| Novo Nordisk AS | 2 | $2,940 |
| Vertex | 1 | $433 |
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.
- CAMZYOS$16,819
How this compares
$62,940 in reported general payments places this provider in the 90th percentile of 750 cardiovascular disease providers in Massachusetts.
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 |
|---|---|---|
| EliquisApixaban | 26 | $31,965 |
| Metoprolol Succinate | 60 | $1,041 |
| Verapamil ErVerapamil Hcl | 12 | $422 |
| Atorvastatin Calcium | 41 | $406 |
