J329 - Long-term sinus infection or inflammation that has lasted more than 12 weeks

International Classification of Diseases

Last updated: 10/3/2025

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

Chronic sinusitis is a condition where the spaces inside your nose and head (called sinuses) remain swollen and inflamed for 12 weeks or longer, despite treatment attempts. This ongoing inflammation can cause symptoms like nasal congestion, facial pressure or pain, reduced sense of smell, and thick nasal discharge. The 'unspecified' part means the exact location of the affected sinuses or the specific cause wasn't identified in your medical record. This is a common condition that can significantly impact quality of life but is generally manageable with proper treatment.

Additional Information

Treatment typically includes nasal saline irrigation, corticosteroid nasal sprays, and addressing underlying causes like allergies. Surgery may be considered for severe cases that don't respond to medical management.
