0.000What This Code Means
Death of bone tissue without infection in the upper arm bone (humerus) when the specific side is not documented.
Coding Tips
- •Use only when laterality is truly unspecified in the medical record
- •Attempt to clarify with provider documentation whether right or left humerus is affected
Clinical Significance
Idiopathic aseptic necrosis of unspecified humerus represents bone death in the upper arm when laterality is not documented, indicating a serious condition requiring orthopedic management. This diagnosis suggests potential for significant functional impairment and the need for surgical intervention if conservative treatment fails.
Documentation Requirements
- ✓Documentation of aseptic necrosis involving humerus bone
- ✓Confirmation of idiopathic etiology without identifiable cause
- ✓Imaging studies showing bone necrosis in humeral structures
- ✓Absence of specific laterality documentation in medical record
- ✓Exclusion of infectious causes through clinical assessment
- ✓Upper extremity functional evaluation and limitations
- ✓Treatment plan including conservative or surgical options
- ✓Pain management documentation and patient response
