Human metapneumovirus as the cause of diseases classd elswhr

This code identifies human metapneumovirus (HMPV) as the confirmed etiology of various illnesses, particularly respiratory tract infections. It signifies that HMPV has been identified as the causative agent for conditions classified under other ICD-10-CM codes.

Assign this code when laboratory testing confirms HMPV as the underlying cause of a patient's disease, such as bronchitis, pneumonia, or bronchiolitis. Documentation should clearly state the identification of HMPV and the specific disease it is causing.

• Always sequence this code after the code for the specific disease caused by HMPV (e.g., J20.5 for acute bronchitis due to HMPV).
• Ensure laboratory confirmation of HMPV is present in the medical record.
• Do not use this code if HMPV is merely suspected or if the specific disease caused by HMPV is not documented.
