Other facial nerve disorders

This code signifies a range of conditions affecting the facial nerve (cranial nerve VII) that are not specifically classified elsewhere. These disorders can manifest as weakness, paralysis, or abnormal movements of the facial muscles, impacting expressions, eye closure, and taste sensation. The underlying etiology can vary, including inflammatory, traumatic, or idiopathic causes.

Use this code for documented facial nerve dysfunction when a more specific ICD-9-CM code (e.g., Bell's palsy, Ramsay Hunt syndrome) is not applicable or the specific cause is unknown. Documentation should clearly indicate a facial nerve disorder and rule out more defined conditions. This code is appropriate for conditions like facial nerve neuroma (non-malignant), facial nerve entrapment, or other unspecified facial neuropathies.

• Ensure documentation explicitly states "other" or "unspecified" facial nerve disorder if a more specific diagnosis isn't available.
• Do not use this code for Bell's palsy (351.0) or other clearly defined facial nerve conditions.
• Always review the medical record for any underlying cause that might warrant an additional, more specific diagnosis code.
