Congenital cytomegalovirus infection

This code signifies an infection with cytomegalovirus (CMV) that was acquired by the fetus in utero or during birth. It can lead to a range of symptoms from asymptomatic to severe, including neurological deficits, hearing loss, and developmental delays. The infection is present at the time of birth.

Apply this code when documentation confirms a neonate or infant has a CMV infection that was congenitally acquired. This typically involves positive viral cultures, PCR, or serology (IgM) for CMV in the newborn, often with supporting clinical signs or symptoms. Use for cases where the infection is definitively linked to prenatal or perinatal transmission.

• Differentiate from CMV infections acquired postnatally; those would use codes from the 078.5 category.
• Always review physician documentation for explicit statements of "congenital CMV" or evidence of in-utero/perinatal transmission.
• Code any associated manifestations or sequelae of the congenital CMV infection, such as microcephaly or sensorineural hearing loss, in addition to this code.
