INTEGRATING A FRAILTY INDEX INTO THE CMS HIERARCHICAL CONDITION CATEGORY MODEL FOR PREDICTING HEALTH CARE COSTS

Abstract

The Centers for Medicare and Medicaid Services Hierarchical Condition Category (CMS-HCC) score is a standard risk adjustment tool to predict total Medicare costs. We examined whether a claims-based frailty index (CFI) could enhance the predictive capability of the CMS-HCC score.
