Since January 2026, ABA has been at the center of the most aggressive federal Medicaid enforcement push in a decade — characterized by congressional investigations across 10 states, a new CMS anti-fraud initiative, and state-level changes to reimbursements. Regulators and payers are using technology to proactively hunt for fraud, waste, and abuse. For ABA operators, the stakes are immediate: documentation that was once good enough is triggering review, and organizations are at heightened risk for clawbacks.

In this session, Zach Rosen, CEO of Brellium, and Rebecca Geist — a healthcare strategy executive and National Director of Government Programs Business Development and Strategy at Kaiser Permanente — break down the enforcement landscape from both the provider and payer side.
Together, they'll cover which documentation patterns are drawing scrutiny, what the shift from "pay-and-chase" to "detect-and-deploy" means in practice, and what organizations should be doing now — whether the priority is protecting this quarter's revenue or preparing to scale compliance systems nationwide.
