What is the purpose of the HCC coding framework?

• A. To group unrelated symptoms for research
• B. To categorize medications for formulary decisions
• C. To assign risk adjustment factors to related diagnoses that reflect severity and projected costs
• D. To determine hospital room rates

Answer: (C)

At its heart, the HCC coding framework translates a patient’s health conditions into a risk score that predicts future medical costs. Diagnoses are grouped into Hierarchical Condition Categories, with each category assigned a weight that reflects expected resource use and severity. The hierarchy ensures that when a patient has multiple related conditions, only the most severe state contributes to the score, preventing double counting. That risk score then helps determine risk-adjusted payments to health plans, so plans are fairly compensated for enrolling sicker patients and providing necessary care. This isn’t used to group unrelated symptoms for research, nor to categorize medications for formulary decisions, nor to set hospital room rates.
