Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $48,031 of the $48,724 with a category attached, or 98.6%. Roche Diagnostics Operations, Inc. accounts for 95.8% of it on its own, with 4 other manufacturers making up the rest. Reporting peaked in 2020 at $27,305 and has fallen 94.8% since, to $1,431 in 2025. Among endocrinology, diabetes & metabolism 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.

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.

| Regeneron | 1 | $1,376 |
| Sumitomo Pharma America, Inc. | 8 | $581 |
| Amgen | 1 | $65 |
| Baxter Healthcare | 1 | $47 |
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.

- cobas 6000 Core Unit$10,750
- cobas 6800 System$2,150

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 |
|---|---|---|
| SynthroidLevothyroxine Sodium | 121 | $11,086 |
| Levothyroxine Sodium | 398 | $3,622 |
| LevoxylLevothyroxine Sodium | 33 | $1,030 |
| Calcitriol | 33 | $747 |
| Methimazole | 77 | $678 |
