CMS Innovation Models

CMS Innovation Center activity this week centered on mandatory and downside-risk models: hospitals and ACO stakeholders are pressing CMS on the Comprehensive Care for Joint Replacement Expanded model (CJR-X), with Premier and AHA seeking changes to financial methodology, quality measurement, and operational burden as CMS moves deeper into episode-based accountability. At the same time, ACOs preparing for MSSP and the LEAD Model are sharpening risk-mitigation strategies, with stop-loss emerging as a key tool for organizations taking on more downside exposure (Wakely analysis). A separate political fault line is forming around CMS’ WISeR Medicare AI prior authorization pilot, as House appropriators advanced language to block it—signaling that under the Trump administration’s CMS leadership, technology-enabled utilization management may face congressional resistance even as CMMI expands payment and care-delivery experimentation (Healthcare Dive).
