What This Code Means

Death of bone tissue affecting multiple bones throughout the body, occurring without a known cause.

Coding Tips

  • This code indicates involvement of 2 or more separate bone sites
  • Consider documenting which specific sites are affected for clinical clarity

Clinical Significance

Idiopathic aseptic necrosis affecting multiple bone sites represents a systemic condition of bone death without infection or identifiable cause, indicating significant disease burden requiring comprehensive management. This diagnosis suggests a more severe condition that may impact multiple functional areas and require multidisciplinary care coordination.

Documentation Requirements

  • Documentation of multiple bone sites affected
  • Specification of at least two distinct anatomical locations
  • Confirmation of aseptic nature across all sites
  • Documentation that cause is idiopathic/unknown
  • Imaging evidence of osteonecrosis at multiple locations
  • Clinical findings consistent with multi-site involvement
  • Exclusion of systemic causes that could explain multiple sites
  • Comprehensive functional assessment
