What This Code Means

A chronic bone infection affecting multiple areas of the forearm bones (radius and ulna) when the specific side (left or right) is not documented or specified.

Coding Tips

  • Use this code only when laterality cannot be determined from the medical record
  • Query the provider if laterality is missing, as more specific codes are preferred

Clinical Significance

This diagnosis indicates chronic multifocal osteomyelitis affecting the radius and ulna when laterality is not specified, representing a significant infectious disease requiring long-term management. The condition poses risks for functional impairment and potential systemic complications if inadequately treated.

Documentation Requirements

  • Documentation of radius and ulna involvement (both bones)
  • Evidence of chronic infection (>6 weeks duration or recurrent)
  • Confirmation of multifocal pattern within affected bones
  • Radiological findings consistent with chronic osteomyelitis
  • Clinical symptoms (bone pain, swelling, decreased function)
  • Laboratory evidence (inflammatory markers, culture results when available)
  • Treatment documentation (antibiotic regimens, surgical history)
  • Absence of specific laterality documentation in the medical record
