2026 Risk Adjustment Coding and HCC Guide (Softbound)
Optum | 2026
The 2026 edition of the Risk Adjustment Coding and HCC Guide brings together hard-to-find information about risk adjustment (RA) coding and hierarchical condition categories (HCCs) in a new comprehensive resource that explains this complex reimbursement methodology. Now your organization will have a guide that provides the “big picture” and the fine detail needed to document, code, and report essential information to ensure accurate risk levels are assigned, and appropriate reimbursement received.
Originally developed for use by Medicare Advantage (MA) plans, HCCs are now used in a variety of value-based reimbursement (VBR) programs. Our guide helps you navigate the shift from a fee-for-service environment to VBR and provides the tools necessary to ensure risk levels and resources are aligned.
