Glossopharyngeal neuralgia

This code represents a rare neurological condition characterized by recurrent, severe, paroxysmal pain in the distribution of the glossopharyngeal nerve. The pain typically affects the ear, tonsillar area, pharynx, and sometimes the neck or tongue. It is often triggered by swallowing, coughing, or speaking.

Use this code for patients presenting with classic symptoms of glossopharyngeal neuralgia, confirmed by a physician. Documentation should clearly describe the location, character (e.g., sharp, shooting), and triggers of the pain, along with findings from a neurological examination. This diagnosis is typically made after ruling out other causes of facial or throat pain.

• Differentiate from trigeminal neuralgia (G50.0 in ICD-10-CM, 350.1 in ICD-9-CM), which affects a different nerve distribution.
• Ensure documentation specifies "neuralgia" and not just generalized throat pain.
• Consider any associated conditions or etiologies, such as vascular compression, if documented, for additional coding.
