Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $2,945 of the $4,859 with a category attached, or 60.6%. Regeneron accounts for 87.4% of it on its own, with 1 other manufacturer making up the rest. Among internal medicine 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 17 payments — averaging $285.80 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Regeneron$4K
- Vertex$614
Across 10 payments — averaging $12,554 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Vertex$126K
What the payments were for
- Consulting fees$1,71335%
- Travel & lodging$2,94561%
- Food & beverage$2004%
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.
How this compares
$4,859 in reported general payments places this provider in the 90th percentile of 4,983 internal medicine 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.
