What does a 'code pair' approach in HCC mapping entail?

• A. Code pair approaches require documented severity or complications to support HCC mapping.
• B. Code pairs map automatically without documentation.
• C. Code pairs are never used in HCC mapping.
• D. Code pairs always double-count HCCs.

Answer: (A)

The idea behind a code pair approach in HCC mapping is that an HCC is only assigned when a diagnosis code is paired with a separate code that documents its severity or a related complication. This pairing ensures the risk score reflects not just the presence of a condition, but how severe it is or what complications exist. In practice, many conditions only trigger an HCC when there is explicit documentation of their severity or a complication, so the mapping relies on both codes being present in the record. That’s why this approach isn’t automatic—you can’t map an HCC from a single diagnosis code alone unless the paired severity/complication code is also documented. It’s a common method precisely to improve accuracy by tying the condition to its clinical impact, rather than counting every listed diagnosis. It doesn’t inherently double-count—HCCs are assigned based on valid pairs per guidelines, and if the paired documentation isn’t present, the HCC wouldn’t be mapped.
