What This Code Means

Death of bone tissue in the right shinbone (tibia) without infection, occurring without a known cause. This condition can cause pain and weakness in the lower leg and may affect walking ability.

Coding Tips

• •Confirm right side is documented in the medical record
• •Distinguish from fibular necrosis (M87.064-066) which affects the smaller bone in the lower leg

Clinical Significance

Idiopathic aseptic necrosis of the right tibia represents bone death in the shinbone without identifiable cause, potentially causing pain and weakness in the lower leg affecting walking ability. This condition can cause pain and weakness in the lower leg and may affect walking ability, potentially requiring surgical intervention to prevent bone collapse.

Documentation Requirements

• ✓Documentation of aseptic necrosis specifically affecting right tibia
• ✓Confirmation of idiopathic etiology with no underlying cause identified
• ✓Imaging evidence showing bone necrosis in right tibial structures
• ✓Clear laterality documentation specifying right tibia involvement
• ✓Exclusion of infectious processes through clinical evaluation
• ✓Assessment of lower leg function, weight-bearing, and gait
• ✓Treatment plan including conservative management or surgical options
• ✓Documentation of pain and functional limitations in ambulation
