What This Code Means

A long-term bone infection from bloodstream bacteria affecting multiple bones or sites throughout the body simultaneously.

Coding Tips

•Document all affected sites clearly in the medical record
•This code indicates disseminated or widespread chronic hematogenous osteomyelitis

Clinical Significance

Chronic hematogenous osteomyelitis affecting multiple sites represents the most severe form of bone infection, indicating either systemic spread or multiple independent foci. This condition requires aggressive treatment and carries significant morbidity risk, often necessitating multidisciplinary care and prolonged hospitalization.

Documentation Requirements

✓Documentation of chronic duration (>6 weeks or recurrent episodes)
✓Evidence of hematogenous spread affecting multiple bone sites
✓Identification of at least two distinct anatomical locations
✓Imaging studies demonstrating multifocal bone infection
✓Laboratory evidence of systemic infection or inflammation
✓Assessment of overall functional status and disability
✓Comprehensive treatment plan addressing multiple sites
✓Documentation of complications or secondary effects
