Other lesions of median nerve, bilateral upper limbs

This diagnosis code signifies the presence of non-specific lesions affecting the median nerve in both upper extremities. These lesions are not classified as carpal tunnel syndrome or other specific median nerve entrapments. It indicates a bilateral presentation of median nerve pathology that doesn't fit more precise diagnostic categories.

Use this code when documentation clearly indicates a bilateral median nerve lesion that is not carpal tunnel syndrome, traumatic, or otherwise specified. This may include findings from nerve conduction studies or electromyography (NCS/EMG) showing median nerve dysfunction without a definitive etiology or specific anatomical entrapment site.

• Ensure documentation explicitly states "bilateral" involvement of the median nerve.
• Distinguish from G56.03 (bilateral carpal tunnel syndrome) and other specific median nerve entrapments.
• Look for supporting diagnostic test results (e.g., NCS/EMG) that confirm median nerve involvement without a more precise diagnosis.
