What This Code Means

Death of bone tissue in the right thighbone (femur) caused by a previous injury or trauma to that area.

Coding Tips

• •Verify documentation specifies right femur and confirms osteonecrosis is due to previous trauma rather than other causes like idiopathic or radiation-related
• •This code requires documentation of the causal relationship between the prior trauma and current osteonecrosis; review medical records for injury history

Clinical Significance

Right femoral osteonecrosis secondary to trauma represents a major weight-bearing bone complication that significantly impacts mobility and quality of life. This condition often progresses to femoral head collapse without appropriate intervention, potentially requiring total hip replacement and extensive rehabilitation.

Documentation Requirements

• ✓Specific identification of right femur involvement
• ✓Clear documentation of previous trauma to right hip/thigh area
• ✓Radiological evidence of femoral bone necrosis
• ✓Location within femur (head, neck, shaft) when specified
• ✓Current weight-bearing capacity and mobility status
• ✓Pain assessment and functional limitations
• ✓Risk factors for progression and complications
• ✓Treatment plan and surgical considerations
