Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (47.0%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. 21 manufacturers reported payments, led by Johnson & Johnson at 41.2% of the total. Reporting peaked in 2024 at $31,157 and has fallen 73.5% since, to $8,244 in 2025. Among critical care medicine 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 219 payments — averaging $278.71 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments

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.

How this compares
$61,037 in reported general payments places this provider in the 95th percentile of 141 critical care medicine 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 |
|---|---|---|
| Trelegy ElliptaFluticasone/Umeclidin/Vilanter | 45 | $37,862 |
| Stiolto RespimatTiotropium Br/Olodaterol Hcl | 15 | $10,296 |
| Breo ElliptaFluticasone/Vilanterol | 18 | $10,246 |
| Combivent RespimatIpratropium/Albuterol Sulfate | 11 | $8,260 |
| Spiriva RespimatTiotropium Bromide | 11 | $5,575 |
| Prednisone | 26 | $69 |
Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| GSKTrelegy Ellipta, Breo Ellipta | $109 | $48,10763 claims |
| Boehringer IngelheimStiolto Respimat, Combivent Respimat, Spiriva Respimat | $25 | $24,13137 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 141 critical care medicine providers in Colorado.
