Measles complicated by pneumonia

This code identifies measles infection that has progressed to involve the lungs, specifically manifesting as pneumonia. It signifies a severe complication of measles, indicating a more serious clinical presentation requiring specific management.

Apply this code when documentation clearly states a diagnosis of measles and explicitly mentions pneumonia as a complication. This typically occurs in cases where a patient with confirmed measles develops respiratory symptoms, and imaging or clinical findings confirm pneumonia.

• Always ensure documentation explicitly links the pneumonia to the measles infection.
• Do not use this code if pneumonia is present but not directly attributed to measles; consider separate codes for unrelated conditions.
• Sequence this code as the primary diagnosis when measles with pneumonia is the reason for the encounter.
