How to Build an Audit-Proof HCC Suspect-Condition Pipeline in Three Stages

A technical walkthrough outlines the three core stages — identification, validation, and capture — required to build a defensible suspect-condition pipeline for risk adjustment coding. The identification stage uses clinical signals such as lab results, medications, and prior diagnoses to flag candidate HCC codes for review. Validation ensures every suspect carries documented evidence before reaching a coder, with an empty evidence array treated as a hard gate rather than a soft warning. The capture stage routes validated suspects to clinicians with inline evidence to support efficient confirmation and documentation. Under CMS-HCC V28 audit standards, two key metrics — validated-suspect capture rate and audit-fail rate — are recommended to distinguish durable revenue from mere volume.
