What This Code Means

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

Coding Tips

• •Ensure documentation clearly identifies the tibia (not fibula) and specifies right side to avoid confusion with fibular osteonecrosis codes
• •Review imaging reports to confirm osteonecrosis diagnosis and verify it is attributed to previous trauma

Clinical Significance

Right tibial osteonecrosis following trauma affects a major weight-bearing bone critical for ambulation and stability. This condition can lead to significant functional impairment, chronic pain, and potential need for complex orthopedic procedures including bone grafting or joint reconstruction.

Documentation Requirements

• ✓Specific identification of right tibia involvement
• ✓Documentation of previous trauma to right lower leg
• ✓Clinical or radiological evidence of bone necrosis in tibial bone
• ✓Location within tibia (proximal, shaft, distal) if specified
• ✓Current weight-bearing status and ambulation capacity
• ✓Assessment of pain levels and functional limitations
• ✓Treatment history and response to interventions
• ✓Impact on mobility and activities of daily living
