Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,665 of the $4,806 with a category attached, or 76.3%. 18 manufacturers reported payments, led by Alcon at 46.9% of the total. Reporting peaked in 2023 at $1,913 and has fallen 57.2% since, to $820 in 2025. Among optometrist clinicians in NV with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 45 payments — averaging $106.79 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

How this compares
$4,806 in reported general payments places this provider in the 90th percentile of 494 optometrist providers in Nevada.
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.
