Postmeasles pneumonia

This code signifies pneumonia that develops as a complication following a measles infection. It indicates a secondary bacterial or viral lung infection occurring in a patient who has recently or concurrently experienced measles.

Use this code when documentation clearly states a diagnosis of pneumonia occurring after or in conjunction with a measles infection. Supporting documentation should include evidence of both measles and the subsequent development of pneumonia, such as chest X-ray findings, fever, cough, and respiratory distress.

• Always sequence the measles code (055.x) first, followed by this code for the pneumonia.
• Do not use this code for pneumonia unrelated to a measles infection; consider other pneumonia codes (e.g., 480-486).
• Ensure the medical record explicitly links the pneumonia to the measles infection for accurate coding.
