0.000What This Code Means
Death of bone tissue in the shinbone (tibia) without infection, occurring without a known cause, when the specific side is not specified. This condition can cause pain and weakness in the lower leg and may affect walking ability.
Coding Tips
- •Use this code only when laterality cannot be determined from documentation
- •Query the provider to clarify whether the condition affects the right tibia, left tibia, or both
Clinical Significance
Idiopathic aseptic necrosis of unspecified tibia represents bone death in the shinbone when laterality is not documented, 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, requiring orthopedic evaluation and management.
Documentation Requirements
- ✓Documentation of aseptic necrosis affecting tibia bone
- ✓Confirmation of idiopathic etiology without identifiable cause
- ✓Imaging studies showing bone necrosis in tibial structures
- ✓Absence of specific laterality documentation in medical record
- ✓Exclusion of infectious causes through clinical assessment
- ✓Lower leg functional assessment including weight-bearing ability
- ✓Treatment plan documentation including therapeutic interventions
- ✓Pain management strategies and ambulation impact assessment
