Healthcare Cost Trends

CMS is moving cost containment back toward more prescriptive Medicare payment models: the proposed nationwide, mandatory CJR-X bundled payment model would make most hospitals accountable for total episode spending and post-acute coordination for hip, knee, and ankle replacements beginning Oct. 1, 2027, signaling renewed federal appetite for mandatory episode-based risk under the Trump administration (Hall Render). At the same time, CMS is testing a more technology-enabled, voluntary path through the ACCESS model, with 150+ participants tying payment to chronic disease management outcomes, creating a dual-track VBC strategy: mandatory bundles for high-cost procedural episodes and lighter-touch innovation models for longitudinal population health (Healthcare Finance). For health systems, ACOs, and payers, the strategic implication is that Medicare cost-trend management is shifting from broad VBC rhetoric to operational execution—episode control, home health and post-acute alignment, specialty engagement, and scalable tech partnerships will increasingly determine margin performance.
