Hierarchical Condition Categories (HCC) is a coding system developed by Medicare to pay Medicare Advantage insurance companies, based on demographics and the disease burden of the beneficiaries. Though HCCs can seem intimidating, they don’t have to be a risky business.Medical practices depend on coding for more than payment. Diagnosis coding communicates the disease burden of an individual patient, as well as a panel of patients within a practice. In the transition from volume-to-value, diagnosis coding changes the process of reimbursement and predicts the costs of caring for patients. In this new world, medical practices must understand how risk adjusted diagnosis coding works.With that in mind, we’ve compiled the educational resources on this page to guide medical coders and practitioners in following ICD-10 rules and accurately reporting diagnosis codes on claim forms.
