0.000What This Code Means
Death of bone tissue in the upper arm bone (humerus) of unspecified side caused by a secondary condition or factor.
Coding Tips
- •Query the provider for laterality information when not documented
- •Use only when bilateral involvement is not present and laterality truly cannot be determined
Clinical Significance
Unspecified humerus secondary osteonecrosis represents bone death from identifiable non-traumatic causes when laterality cannot be determined. This condition significantly impacts upper extremity function and requires management of both the underlying condition and bone pathology.
Documentation Requirements
- ✓Documentation of underlying secondary cause of osteonecrosis
- ✓Imaging evidence of humeral osteonecrosis without specified side
- ✓Clinical findings consistent with humeral dysfunction
- ✓Documentation explaining why laterality is unspecified
- ✓History of predisposing factors for secondary osteonecrosis
- ✓Exclusion of traumatic and idiopathic causes
- ✓Provider assessment of secondary nature
- ✓Evidence of bone death through diagnostic studies
