Penstock Information

Penstock is a human-led, tech-enabled payment integrity company that helps health plans recover more, prevent future overpayments, and strengthen long-term payment accuracy. We combine deep audit expertise, advanced analytics, and continuous innovation to uncover what others miss and turn post-pay findings into actionable insight to prevent future overpayments. Our team includes clinicians, certified coders, auditors, data scientists, and payment integrity specialists who work across Commercial, Medicare Advantage, and Medicaid lines of business. We deliver post-pay data mining, post-pay chart review, second-look chart review, pre-pay chart review, and specialty programs such as HCRA audits. By validating issues in post-pay and translating those findings upstream, we help health plans continuously improve both recovery and prevention efforts.
