0.000What This Code Means
Death of bone tissue in the shinbone caused by an underlying condition or treatment when the specific side is not documented or applies to both sides.
Coding Tips
- •Use this code only when laterality cannot be determined from the medical record
- •Request clarification from the provider regarding right, left, or bilateral involvement
Clinical Significance
This diagnosis represents secondary osteonecrosis of the tibia when laterality is not specified, caused by underlying conditions that can significantly impact weight-bearing and mobility. It requires identification of the causative factor and monitoring for complications.
Documentation Requirements
- ✓Documentation of osteonecrosis affecting tibia without side specification
- ✓Identification of underlying cause (e.g., corticosteroid use, radiation therapy, sickle cell disease)
- ✓Imaging findings confirming tibial bone necrosis
- ✓Clinical symptoms such as shin pain, swelling, or difficulty walking
- ✓Functional limitations affecting mobility
- ✓Duration and progression of condition
- ✓Treatment history and response
- ✓Reason why laterality cannot be determined or if bilateral involvement
