Hierarchical Condition Category (HCC) risk adjustment uses diagnosis information and other patient characteristics to estimate expected healthcare costs. The CMS-HCC model supports Medicare Advantage payment risk adjustment. The HHS-HCC model serves the individual and small-group insurance markets under the Affordable Care Act; the models have different purposes and mappings.
ReviewMate provides a CMS-HCC auditing module with performance targets, averages and options for managing HCC reviews. Teams can connect risk adjustment review with the broader medical coding audit platform. For HHS-HCC requirements, contact ReviewMate to confirm available capabilities.
No. HCC mapping depends on the risk adjustment model and applicable year. A diagnosis must be supported by the medical record and meet applicable coding and reporting requirements; an HCC mapping alone does not establish that a diagnosis should be reported.
For model information and official mapping resources, see CMS Medicare Advantage risk adjustment guidance. Explore the ReviewMate medical coding encoder for related coding and HCC review tools.
