Reporting peaked in 2019 at $400 and has fallen 72.9% since, to $109 in 2025.

How this compares
$851 in reported general payments places this provider in the 65th percentile of 274 obstetrics & gynecology providers in Iowa.
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.
