Mucopurulent chronic bronchitis

This code signifies a persistent inflammation of the bronchial tubes characterized by the production of mucus and pus. It represents a chronic form of bronchitis where the sputum contains both mucoid and purulent material, indicating an ongoing infectious or inflammatory process.

Assign this code when documentation explicitly states "mucopurulent chronic bronchitis" or describes chronic bronchitis with purulent sputum production. This diagnosis is typically made based on clinical presentation, sputum analysis, and a history of chronic cough and sputum production for at least three months in two consecutive years.

• Differentiate from simple chronic bronchitis (J41.0) which lacks the purulent component.
• Do not use if the bronchitis is acute or subacute; this code is specifically for chronic forms.
• Consider additional codes for any identified infectious agents (e.g., bacteria, viruses) if documented.
