Payments from drug & device makers
What this record shows
The money is spread across several categories — royalties or licence payments (57.6%), consulting fees and other — rather than concentrated in one kind of arrangement. Medtronic accounts for 67.2% of it on its own, with 28 other manufacturers making up the rest. Reporting peaked in 2020 at $686,288 and has fallen 94.7% since, to $36,484 in 2025. Among vascular & interventional radiology clinicians in CO 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 327 payments — averaging $3325.23 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| Nitrofurantoin Mono-MacroNitrofurantoin Monohyd/M-Cryst | 66 | $536 |
| Methylprednisolone | 81 | $497 |
| Oxybutynin Chloride | 68 | $296 |
| Tamsulosin Hcl | 30 | $266 |
| Oxycodone Hcl | 58 | $209 |
| Ondansetron Hcl | 14 | $71 |
