0.000What This Code Means
Death of bone tissue in the left upper arm bone (humerus) caused by a secondary condition or factor.
Coding Tips
- •Verify laterality is clearly documented as 'left' in the clinical record
- •Document any functional impairment or treatment plan related to this osteonecrosis for comprehensive coding
Clinical Significance
Left humerus secondary osteonecrosis indicates bone death from identifiable non-traumatic causes affecting the dominant arm in most patients. This condition requires comprehensive management addressing both the underlying cause and the bone pathology to prevent progressive functional loss.
Documentation Requirements
- ✓Clear documentation of secondary cause of osteonecrosis
- ✓Radiological evidence of bone necrosis in left humerus
- ✓Clinical assessment showing left arm impairment
- ✓History of risk factors such as steroids or systemic disease
- ✓Exclusion of trauma and idiopathic causes
- ✓Documentation of symptoms and functional impact
- ✓Provider correlation of secondary etiology
- ✓Evidence of compromised bone blood supply
