A Medicare Advantage panel at a multi-specialty group asks what Hierarchical Condition Categories (HCCs) primarily do with ICD-10-CM diagnoses. Which statement best describes their purpose?
Select an answer to reveal the explanation.
Short Explanation
HCCs are buckets that gather related diagnoses so payors can score how sick a population is. For Medicare Advantage, those buckets feed risk adjustment—not CPT replacement or NCCI overrides. Coders still report real ICD-10-CM; the model maps eligible codes into categories.
Full Explanation
Hierarchical Condition Categories organize specified ICD-10-CM diagnoses into clinical categories used in Medicare Advantage risk adjustment. Accurate diagnosis capture influences risk scores that affect MA payment, but HCCs do not replace CPT assignment, do not function as inpatient DRGs for facility payment on professional claims, and are not NCCI modifiers. The coder’s role remains assigning supported diagnoses; the model performs the category mapping.
