Pneumonia due to respiratory syncytial virus

This code identifies an acute inflammatory condition of the lungs caused specifically by the Respiratory Syncytial Virus (RSV). It signifies a lower respiratory tract infection, often presenting with symptoms like cough, fever, and difficulty breathing, particularly common in infants and young children.

Apply this code when documentation clearly states a diagnosis of pneumonia and explicitly identifies RSV as the causative agent. This is frequently seen in pediatric populations during RSV season, but can also affect immunocompromised adults. Supporting documentation should include laboratory confirmation of RSV (e.g., PCR, rapid antigen test) or a strong clinical diagnosis by a physician.

• Ensure the documentation specifies "pneumonia" and not just "bronchiolitis" or "RSV infection" without lung involvement.
• Do not use if the pneumonia is due to another viral agent; specific codes exist for other viral pneumonias.
• Consider sequencing with codes for associated symptoms or complications, such as respiratory failure, if documented.
