What This Code Means

Death of bone tissue in the left smaller bone of the lower leg (fibula) caused by a previous injury or trauma to that area.

Coding Tips

  • Verify left fibula is specifically documented to differentiate from right fibula (M87.264) or unspecified fibula (M87.266)
  • Ensure the osteonecrosis is attributed to previous trauma and not other etiologies

Clinical Significance

Left fibular osteonecrosis secondary to trauma affects the lateral support bone of the lower leg, potentially compromising ankle stability and normal gait pattern. This condition requires monitoring for progression and may necessitate orthopedic intervention to prevent further complications.

Documentation Requirements

  • Clear identification of left fibula involvement
  • Documentation of previous trauma to left lower leg area
  • Evidence of bone necrosis in left fibular structures
  • Assessment of ankle function and stability
  • Current pain assessment and mobility evaluation
  • Any concurrent tibial or ankle pathology
  • Treatment attempts and patient response
  • Impact on gait and weight-bearing activities
