HCC stands for Hierarchical Condition Category. It refers to a system of medical coding used by insurance companies to determine patients' future medical needs for the next year. Only life altering medical conditions are recorded in medical coding, such as a diabetes diagnosis, end stage renal disease, and others. HCC Assistant is an innovative EHR-integrated intelligent HCC coding tool which helps providers improve their risk-adjustment documentation in real-time at the point of care by showing all possible HCC-related diagnoses.
