What is an HCC?

What is an HCC?

• A. A smoking cessation program
• B. A hospital accreditation standard
• C. A grouping of similar diagnoses into one related category used in risk adjustment.
• D. A billing code for surgery

Answer: (C)

An HCC is a grouping of related diagnoses used in risk adjustment to predict future healthcare costs. In payer models, each patient’s ICD-10-CM codes map to one or more HCCs, and when several related conditions are present, they’re collapsed into the most appropriate, typically the highest-severity category. This keeps the risk score from double-counting similar conditions and ensures payments reflect overall health risk rather than counting every code separately. It’s a tool used by programs like CMS in Medicare Advantage to adjust payments for sicker patients. This concept isn’t a smoking cessation program, an accreditation standard, or a billing code for surgery.
