Disorders of multiple cranial nerves

This code signifies a neurological condition affecting two or more cranial nerves simultaneously, without a more specific diagnosis available. It indicates a generalized dysfunction rather than a localized lesion impacting a single cranial nerve.

Apply this code when documentation indicates a patient presents with symptoms referable to multiple cranial nerves, such as combined vision changes, facial weakness, and swallowing difficulties, and a more precise etiology or specific cranial nerve disorder code is not yet determined. Supporting documentation includes neurological examination findings, imaging reports, and physician notes detailing the involvement of several cranial nerves.

• Do not use this code if a more specific diagnosis for multiple cranial nerve involvement (e.g., specific syndromes) is documented.
• Always sequence this code after the primary condition or underlying cause, if known and documented.
• Ensure the medical record clearly supports the involvement of multiple cranial nerves, not just one.
