J338 - Other types of nasal or sinus polyps

International Classification of Diseases

Last updated: 5/8/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code refers to polyps (small, non-cancerous growths) found in the sinuses that don't fit into other specific polyp categories. Nasal and sinus polyps are soft, painless growths that develop in the lining of the nasal passages or sinuses. They often result from chronic inflammation due to conditions like allergies, asthma, or recurring infections. While these polyps are benign (not cancerous), they can cause symptoms like nasal congestion, reduced sense of smell, runny nose, or facial pressure. The 'other' classification means these are polyps that have specific characteristics that distinguish them from the more common types of nasal polyps.

Additional Information

This is a diagnostic code used for billing and medical record purposes. Treatment options vary depending on the size and symptoms caused by the polyps. Many patients can manage symptoms with medications, while others may need surgical intervention.
