E&M services are among the most frequently billed codes in any plan but understanding whether they’re appropriate requires more than reviewing a chart or two. Penstock analyzes provider-level coding behavior at scale, flagging when E&M levels trend higher than clinical expectations or peer norms. From there, we transform complex analytics into guidance that makes sense to providers, supports constructive conversations, and drives measurable improvement.
Services: Upcoding Prevention Program
invisible cost creep.
Small shifts in E&M coding can compound into significant, unnecessary spend— and too often go unnoticed. We find those patterns early and work with our clients and their providers through clear education and evidence-based feedback to correct behaviors and avoid future unnecessary costs.
What We Do
Spot what others overlook
Our analytics highlight true coding outliers, not just high billers, so plans can focus on providers whose patterns meaningfully diverge from expected norms.
Bring providers the clarity they need
We create provider-ready summaries that clearly outline what was billed, what guidelines support, and how behavior compares to peers, removing ambiguity and defensiveness.
Make changes stick long term
Scheduled re-audits track whether coding accuracy improves and stays aligned with expectations, reinforcing better habits and preventing future drift.
