Disorders of vagus nerve

This code represents a range of conditions affecting the tenth cranial nerve, the vagus nerve. These disorders can manifest as dysfunction in various organ systems, including the heart, lungs, gastrointestinal tract, and larynx, due to the vagus nerve's extensive innervation. Symptoms often relate to autonomic nervous system imbalance or motor/sensory deficits.

Use this code when documentation explicitly states a disorder or neuropathy of the vagus nerve. This includes conditions like vagal neuropathy, vagal nerve palsy, or other specific diagnoses directly impacting the function of the vagus nerve. Supporting documentation should detail the clinical findings and diagnostic workup confirming vagal nerve involvement.

• Do not use this code for symptoms that could be related to vagal nerve dysfunction without a definitive diagnosis of a vagus nerve disorder.
• Specify laterality if documented (e.g., right, left, bilateral) using a more specific subcategory if available.
• Code any underlying cause or associated conditions (e.g., diabetes, autoimmune disease) as additional diagnoses.
