Full definition
HCC (Hierarchical Condition Categories) is the CMS risk-adjustment model used to set Medicare Advantage capitation payments. Patient-specific risk adjustment factor (RAF) is calculated from documented chronic conditions per ICD-10 codes that map to HCCs. Higher-RAF patients require more care; CMS pays plans more for them.
Accurate HCC coding is operationally critical for MA-contracted providers. Under-coding leaves money on the table — patients with documented conditions whose ICD codes weren't submitted result in lower-than-actual RAF, lower plan payment, and constrained quality-investment budget. Over-coding (documenting conditions not actually present, or upcoding severity) triggers CMS Risk Adjustment Data Validation (RADV) audit and recoupment.
For MOVO-X clinic deployments serving MA-heavy populations: HCC-aware NLP coding suggestion at the encounter, bidirectional sync with plan-specific HCC requirements, audit trail of every HCC-relevant code change, and dashboards for clinical-coding leadership to monitor accuracy.

Frequently asked
How does MOVO-X help HCC coding?+
NLP-driven HCC code suggestion at the encounter. Clinical-decision support flags conditions documented but not coded. Audit trails on every HCC change.
What's the RADV audit risk?+
CMS audits a sample of MA records each year. Discrepancies between submitted codes and chart documentation result in recoupment + sometimes additional penalties. Disciplined documentation practice is the defence.
