CMS-HCC Model V28 is set to be introduced in 2026 and will introduce a lot of changes related to risk adjustment. Providers have to cope with new documentation, coding changes, and workflow changes.  Among the key effects are the increased clinical-coding alignment, the increased interoperability requirements, and the support of documentation by AI. The first step that organizations should prioritize is to prepare now, based on training staff, updating the systems, and coordinating the strategy with multiple vendors.

The CMS-HCC Model V28 is about to transform the landscape of risk adjustment in healthcare organizations, and healthcare organizations are about to approach a pivotal moment. This transition will not be just another regulatory update, but rather a paradigm shift that will define how providers document patient care, code, and coordinate between various vendor systems.

Modern healthcare delivery has never been more complex than it is today, and organizations are capable of handling as many as steps (in some cases, up to 30 steps) between the initial provider documentation and their ultimate submission to CMS. With the ever-increasing regulatory pressure and the ever-evolving requirements of coding, healthcare executives are realizing that the conventional methods of risk adjustment are no longer adequate.
