0.000What This Code Means
Death of bone tissue in the right upper arm bone (humerus) from causes other than typical classified causes.
Coding Tips
- •Ensure right-sided involvement is documented before coding
- •The humerus is the long bone of the upper arm extending from shoulder to elbow
Clinical Significance
This diagnosis represents osteonecrosis of the right humerus from causes other than the typical classified causes, which can significantly impact upper extremity function and potentially require surgical intervention. It requires identification of the underlying etiology and monitoring for progression.
Documentation Requirements
- ✓Documentation of osteonecrosis affecting right humerus
- ✓Clear description of the underlying cause (other than typical secondary causes)
- ✓Imaging findings confirming humeral bone necrosis (MRI, X-ray, CT)
- ✓Clinical symptoms such as arm pain, weakness, or limited range of motion
- ✓Specific location within humerus (proximal, mid-shaft, distal)
- ✓Functional limitations affecting arm use
- ✓Duration and progression of condition
- ✓Treatment history including conservative and surgical options
