0.000What This Code Means
Death of bone tissue in the left thighbone (femur) caused by a previous injury or trauma to that area.
Coding Tips
- •Confirm laterality is documented as left femur in the clinical record before assigning this code
- •Document the timeline between the original trauma and diagnosis of osteonecrosis to support medical necessity
Clinical Significance
Left femoral osteonecrosis following trauma is a serious complication affecting the major weight-bearing bone, potentially leading to significant disability and need for joint replacement. This condition requires specialized orthopedic management and may significantly impact patient mobility and independence.
Documentation Requirements
- ✓Clear identification of left femur involvement
- ✓Documentation of previous trauma to left hip/thigh area
- ✓Imaging confirmation of osteonecrosis in femoral bone
- ✓Anatomical location within femur (head, neck, shaft) if specified
- ✓Assessment of weight-bearing ability and ambulation status
- ✓Current pain levels and functional capacity
- ✓Treatment history and surgical planning
- ✓Impact on patient mobility and quality of life
