Chr obstructive pulmon disease with (acute) lower resp infct

This code signifies a patient with pre-existing chronic obstructive pulmonary disease (COPD) who has developed an acute lower respiratory infection. This infection, such as acute bronchitis or pneumonia, exacerbates their underlying chronic lung condition. The acute infection contributes to the patient's respiratory distress and symptoms.

Apply this code when documentation clearly indicates a patient with a confirmed diagnosis of COPD also presents with an acute lower respiratory infection. This is typically used for inpatient admissions or outpatient encounters where the acute infection is being treated in the context of their COPD. Supporting documentation includes physician notes detailing both conditions and diagnostic findings (e.g., chest X-ray, sputum culture).

• Always sequence the acute lower respiratory infection code (e.g., J20.-, J18.-) after this code, as this code implies the COPD is the underlying condition.
• Do not use this code for acute exacerbation of COPD without an identified lower respiratory infection; use J44.1 for those cases.
• Ensure the documentation specifies "acute" lower respiratory infection; chronic infections would be coded separately.
