Parvovirus as the cause of diseases classified elsewhere

This code identifies parvovirus as the underlying infectious agent responsible for a disease or condition classified in another chapter of ICD-10-CM. It signifies that parvovirus is the etiology of a manifestation that is coded elsewhere, such as aplastic crisis or hydrops fetalis.

Use this code when documentation explicitly states parvovirus as the cause of a specific disease, and that disease has its own primary code. Common scenarios include parvovirus-induced anemia, myocarditis, or arthropathy. The medical record must clearly link the parvovirus infection to the resulting condition.

• Always sequence this code as a secondary diagnosis, following the code for the specific disease caused by the parvovirus.
• Do not use this code for unspecified viral infections; documentation must confirm parvovirus.
• Ensure the primary diagnosis code accurately reflects the manifestation of the parvovirus infection.
