Laryngocele

This code represents a laryngocele, which is an abnormal, air-filled sac or diverticulum that originates from the laryngeal ventricle. It can be internal, external, or mixed, and may cause symptoms such as hoarseness, dyspnea, or a palpable neck mass.

Assign this code when documentation clearly indicates a diagnosis of laryngocele, regardless of its type or presenting symptoms. Supporting documentation typically includes imaging reports (e.g., CT scan, MRI) or direct laryngoscopy findings confirming the presence of the air-filled sac.

• Differentiate from other laryngeal cysts or masses; ensure the documentation specifies "laryngocele."
• Do not confuse with other laryngeal anomalies unless the specific diagnosis of laryngocele is confirmed.
• Code any associated symptoms (e.g., hoarseness R49.0, dyspnea R06.00) as secondary diagnoses if they are not integral to the laryngocele itself.
