Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $19,750,000 of the $19,770,862 with a category attached, or 99.9%. Vertex accounts for 100.0% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2021 at $18,751,435 and has fallen 100.0% since, to $28 in 2025. Among nephrology clinicians in MA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 23 payments — averaging $859,603 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Travere Therapeutics, Inc.$39

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 |
|---|---|---|
| Vertex | 21 | $19,770,823 |
| Travere Therapeutics, Inc. | 2 | $39 |
How this compares
$19,770,862 in reported general payments places this provider in the 95th percentile of 339 nephrology 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.
