J449 - Chronic lung disease that makes breathing difficult, exact type not specified

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 Obstructive Pulmonary Disease (COPD) is a long-term lung condition that blocks airflow and makes it hard to breathe. This includes conditions like chronic bronchitis (long-term inflammation of breathing tubes) and emphysema (damage to air sacs in lungs). The 'unspecified' designation means the exact type or stage of COPD wasn't detailed in your medical record. Common symptoms include persistent cough, shortness of breath, wheezing, and chest tightness. COPD is often caused by long-term exposure to irritants like cigarette smoke, air pollution, or workplace chemicals. While COPD cannot be cured, proper treatment can help manage symptoms and slow progression.

Additional Information

COPD is a progressive disease that requires ongoing management. Early diagnosis and treatment can significantly improve quality of life and slow disease progression. Smoking cessation is the most important intervention for patients who smoke.
