Unspecified chronic bronchitis

This code signifies a persistent inflammation of the bronchial tubes, characterized by a chronic cough with sputum production for at least three months in two consecutive years, in the absence of other identifiable causes. It indicates a long-standing, non-specific form of bronchitis without further clinical detail regarding obstruction or specific etiology.

Apply this code when documentation clearly states "chronic bronchitis" but lacks further specificity regarding obstructive features (e.g., "chronic obstructive bronchitis") or other defining characteristics. This code is appropriate when the provider has not specified the presence or absence of airway obstruction.

• Avoid using this code if the documentation specifies "chronic obstructive bronchitis" or "COPD with chronic bronchitis," as more specific codes exist.
• Ensure the medical record supports the chronicity of the condition, typically through a history of recurrent or persistent symptoms.
• This code should be a last resort when no further clinical detail about the type or severity of chronic bronchitis is available.
