Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $110,165 of the $119,343 with a category attached, or 92.3%. Gynesonics, Inc. accounts for 73.1% of it on its own, with 12 other manufacturers making up the rest. Reporting peaked in 2022 at $57,562 and has fallen 77.0% since, to $13,230 in 2025.

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.

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 |
|---|---|---|
| Estradiol | 14 | $923 |
| Medroxyprogesterone Acetate | 16 | $87 |
Paid to pharmacies, not to this prescriber.
