HCCs, or Hierarchical Condition Categories, are sets of medical codes that are linked to specific clinical diagnoses. Since 2004, HCCs have been used by the Centers for Medicare and Medicaid Services (CMS) as part of a risk-adjustment model that identifies individuals with serious acute or chronic conditions.
