Abnormal innervation syndrome right lower eyelid

This code signifies a neurological disorder affecting the right lower eyelid, characterized by aberrant nerve supply. This typically results in involuntary movements or abnormal positioning of the eyelid due to misdirected nerve regeneration or congenital anomalies.

Apply this code when documentation specifies abnormal innervation, such as Marcus Gunn jaw-winking phenomenon or other synkinetic movements, specifically impacting the right lower eyelid. Supporting documentation should clearly indicate the laterality and the nature of the innervation abnormality.

• Ensure documentation specifies "right lower eyelid" to differentiate from other eyelid locations or bilateral involvement.
• Do not confuse with simple ptosis or blepharospasm unless abnormal innervation is explicitly stated as the underlying cause.
• Consider co-reporting with codes for associated conditions, such as congenital anomalies, if present and documented.
