Payments from drug & device makers
What this record shows
The money is spread across several categories — education (52.3%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. Gemini Mountain Medical, LLC accounts for 71.8% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2020 at $769 and has fallen 84.9% since, to $116 in 2025. That places this record below the midpoint for orthopaedic surgery clinicians in CO, where the typical reported total is $5,294.
Across 14 payments — averaging $88.26 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$1,236 in reported general payments places this provider in the 25th percentile of 383 orthopaedic surgery providers in Colorado.
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 |
|---|---|---|
| Celecoxib | 19 | $202 |
| Meloxicam | 38 | $122 |
| Oxycodone Hcl | 11 | $48 |
