0.000What This Code Means
Death of bone tissue in the left thigh bone caused by another disease or condition affecting the body.
Coding Tips
- •Document whether the femoral head, neck, or shaft is affected for complete clinical documentation
- •This manifestation code must be accompanied by the code for the underlying disease causing it
Clinical Significance
This diagnosis represents secondary osteonecrosis affecting the left thigh bone (femur), indicating significant bone death caused by an underlying classified disease. The condition requires intensive medical management and has major risk adjustment implications due to mobility concerns and fracture risk.
Documentation Requirements
- ✓Clear documentation of underlying disease causing secondary osteonecrosis
- ✓Specific identification of left thigh/femur as the affected anatomical location
- ✓Radiological confirmation of osteonecrotic changes (MRI, bone scan, CT)
- ✓Provider statement establishing causal relationship to classified disease
- ✓Comprehensive treatment plan for both primary and secondary conditions
- ✓Mobility assessment and weight-bearing status evaluation
- ✓Documentation excluding primary or traumatic causes of bone necrosis
- ✓Monitoring plan for potential complications including pathological fracture
