Adenoviral pneumonia

This code identifies pneumonia specifically caused by an adenovirus infection. It signifies an acute inflammatory condition of the lung parenchyma resulting from adenoviral pathogens, leading to symptoms such as cough, fever, and respiratory distress.

Assign this code when medical record documentation clearly states a diagnosis of adenoviral pneumonia. Supporting documentation should include laboratory confirmation of adenovirus (e.g., PCR, viral culture) or strong clinical evidence in the presence of an adenovirus outbreak.

• Do not use this code if the pneumonia is due to other specified viral agents; use the appropriate code for that specific virus.
• Ensure documentation specifies "adenoviral" to differentiate from other viral pneumonias.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
