Congenital herpesviral [herpes simplex] infection

This code signifies a herpes simplex virus (HSV) infection acquired by a neonate during the perinatal period, either in utero, intrapartum, or postnatally from direct contact with maternal lesions. It can manifest with various symptoms, including skin lesions, ocular involvement, neurological complications, or disseminated disease affecting multiple organs. This condition is distinct from HSV infections acquired later in life.

Use this code when documentation clearly indicates a newborn or infant has been diagnosed with herpes simplex virus infection that was congenitally acquired. This typically involves a positive HSV culture or PCR from the neonate, often in conjunction with maternal history of genital herpes or active lesions at delivery. Documentation should specify the congenital nature of the infection.

• Ensure documentation differentiates congenital HSV from HSV acquired after the neonatal period.
• Do not confuse with other congenital viral infections; confirm HSV etiology.
• Sequence this code as the primary diagnosis when it is the reason for the encounter or hospitalization.
