Chronic obstructive pulmonary disease w (acute) exacerbation

This code signifies a chronic obstructive pulmonary disease (COPD) that is currently experiencing a sudden worsening of symptoms, such as increased shortness of breath, cough, or sputum production. It indicates a temporary but significant deterioration from the patient's usual stable COPD state.

Apply this code when a patient with a documented history of COPD presents with an acute exacerbation requiring medical intervention. Documentation should clearly state "COPD with acute exacerbation" or describe the acute worsening of COPD symptoms.

• Differentiate from J44.0 (COPD with acute bronchitis) – the key is whether the acute event is specifically bronchitis or a general exacerbation.
• Ensure the medical record explicitly states "acute exacerbation" or provides sufficient detail to support this level of severity.
• Do not use for stable COPD without an acute worsening of symptoms; use J44.9 for unspecified COPD.
