In classification systems, MCC stands for which concept?

• A. Major Complication or Comorbidity
• B. Major Condition or Criteria
• C. Minor Complication or Condition
• D. Major Category Code

Answer: (A)

In CDI metrics, diagnoses are used to gauge how severe a case is and how much it costs to treat. MCC stands for Major Complication or Comorbidity, a condition that significantly increases resource use and can raise the DRG weight. This makes it more impactful than a minor issue and helps explain why the hospital’s reimbursement and risk adjustment might be higher. The other options use terms that aren’t standard in this framework, so they don’t fit CDI terminology.
