Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 47 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Optinose US, Inc. accounts for 77.7% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2021 at $264 and has fallen 89.6% since, to $27 in 2025. That places this record below the midpoint for otolaryngology clinicians in NE, where the typical reported total is $741.
Across 47 payments — averaging $14.91 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Who reported the general payments

How this compares
$701 in reported general payments places this provider in the 45th percentile of 86 otolaryngology providers in Nebraska.
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.
