Polyp of vocal cord or larynx

This code signifies the presence of a benign, often pedunculated or sessile, growth originating from the mucosal lining of the vocal cords or other parts of the larynx. These polyps can cause voice changes, hoarseness, or difficulty breathing depending on their size and location. They are typically non-cancerous but require evaluation.

Assign this code when documentation confirms a diagnosis of a vocal cord polyp or a laryngeal polyp, often identified during laryngoscopy. This code is appropriate for initial diagnosis, follow-up, or before surgical removal of the polyp. Supporting documentation includes physician notes detailing the polyp's presence and location.

• Differentiate from vocal cord nodules (singer's nodes) or granulomas, which have distinct ICD-9-CM codes.
• Do not use for malignant laryngeal neoplasms; those require codes from the 161 series.
• Ensure the documentation specifies "polyp" to avoid confusion with other laryngeal lesions.
