Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $84,070 of the $91,596 with a category attached, or 91.8%. Techlab, Inc. accounts for 81.9% of it on its own, with 3 other manufacturers making up the rest. Reporting peaked in 2021 at $25,500 and has fallen 94.0% since, to $1,526 in 2025. Among infectious disease clinicians in VA 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.

How this compares
$91,596 in reported general payments places this provider in the 95th percentile of 194 infectious disease providers in Virginia.
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.
