Multiple cranial nerve palsies

This code signifies the presence of paralysis or paresis affecting multiple cranial nerves simultaneously. It indicates a neurological disorder where several of the twelve cranial nerves, responsible for sensory and motor functions of the head and neck, are impaired.

Use this code when documentation clearly indicates dysfunction of more than one cranial nerve, such as in cases of polyneuropathy, brainstem lesions, or certain autoimmune conditions affecting the nervous system. Supporting documentation should specify which cranial nerves are involved or describe symptoms consistent with multiple cranial nerve deficits.

• Ensure the medical record explicitly states involvement of multiple cranial nerves, not just a single one.
• Investigate the underlying cause of the multiple cranial nerve palsies and code it as the primary diagnosis if known and applicable.
• Differentiate from localized nerve palsies (e.g., Bell's Palsy for facial nerve) which have specific codes.
