Reporting peaked in 2022 at $1,744 and has fallen 95.1% since, to $86 in 2025.

How this compares
$2,293 in reported general payments places this provider in the 85th percentile of 76 primary care providers in Arkansas.
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.
