Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (59.8%), education and travel and lodging — rather than concentrated in one kind of arrangement. Every reported general payment came from a single manufacturer, Coloplast. Among urology clinicians in NH 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 187 payments — averaging $922.45 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Coloplast$172K

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 |
|---|---|---|
| Coloplast | 187 | $172,498 |
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.
- TITAN$159,245
- SenSura Mio$10,500
How this compares
$172,498 in reported general payments places this provider in the 95th percentile of 61 urology providers in New Hampshire.
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.
