ICD Code J43.2

ICD code J43.2 is centrilobular emphysema, a type of chronic lung disease where the central parts of the lung's lobules are damaged, most commonly due to long-term smoking.

1. Presence of chronic, progressive dyspnea (shortness of breath) not fully reversible

2. History of chronic cough, often with minimal sputum production

3. Physical examination findings such as hyperresonance on percussion, decreased breath sounds, or prolonged expiratory phase

4. Imaging (typically high-resolution CT scan) showing focal areas of low attenuation without visible walls, predominantly in the central portions of secondary pulmonary lobules

5. Absence of significant fibrosis or interstitial lung disease

6. Pulmonary function tests demonstrating airflow limitation that is not fully reversible

7. Exclusion of other causes of emphysema, such as panlobular or paraseptal emphysema
