Parainfluenza virus pneumonia

This code identifies pneumonia specifically caused by a parainfluenza virus. It signifies an acute respiratory infection characterized by inflammation of the lung tissue due to this particular viral etiology. Patients typically present with symptoms such as cough, fever, and shortness of breath.

Use this code when documentation clearly states a diagnosis of pneumonia and specifies parainfluenza virus as the causative agent. This diagnosis is often supported by laboratory confirmation (e.g., viral culture, PCR) or strong clinical suspicion in the context of a viral respiratory illness.

• Ensure the documentation explicitly links "pneumonia" with "parainfluenza virus." Avoid using this code for general viral pneumonia without specific viral identification.
• Do not confuse this with influenza virus pneumonia (J09-J11 series) or other specified viral pneumonias.
• Sequence this code as the primary diagnosis when the parainfluenza virus pneumonia is the reason for the encounter.
