Congenital viral disease, unspecified

This code signifies a congenital infection in a newborn caused by an unspecified viral agent. It indicates that the infant was born with a viral disease acquired during gestation or at birth, but the specific virus responsible has not been identified.

Apply this code when documentation confirms a congenital viral infection in a neonate, but the specific viral etiology (e.g., CMV, rubella, herpes simplex) is not documented or is unknown. This code is appropriate when the physician explicitly states "congenital viral disease, unspecified" or similar language without further viral identification.

• Do not use this code if a specific congenital viral infection is identified; instead, code to the specific viral etiology (e.g., P35.0 for congenital rubella).
• This code should only be assigned when the viral agent is truly unspecified. If the documentation suggests a specific virus but lacks definitive confirmation, query the provider.
• Always sequence this code as a principal diagnosis when it is the primary reason for the encounter, or as a secondary diagnosis if another condition is primary.
