Mixed simple and mucopurulent chronic bronchitis

This code signifies a persistent inflammation of the bronchial tubes characterized by both simple (non-productive) and mucopurulent (mucus and pus-producing) features. It indicates a chronic condition where the airways are irritated, leading to a mix of dry and productive coughs over an extended period.

Apply this code when documentation explicitly states "mixed simple and mucopurulent chronic bronchitis" or describes chronic bronchitis with both non-purulent and purulent sputum production. This diagnosis is typically made based on patient history, physical examination findings, and sputum characteristics.

• Ensure the documentation specifies both "simple" and "mucopurulent" characteristics; otherwise, a more general chronic bronchitis code may be appropriate.
• Do not confuse with acute bronchitis or other forms of chronic obstructive pulmonary disease (COPD) unless specifically documented as such.
• Code any associated infections or exacerbations separately, following sequencing guidelines.
