Congenital viral diseases (P35)

The ICD-10 codes P35 through P35.9 specifically categorize congenital viral diseases, which are infections present at birth caused by viruses transmitted from mother to infant. These codes allow healthcare providers to accurately document and identify specific viral conditions affecting newborns.

The section includes detailed codes for conditions such as congenital rubella syndrome (P35.0), also known by terms like rubella pneumonia or rubella encephalitis, which helps differentiate rubella-related birth defects. Congenital cytomegalovirus infection (P35.1) covers infections referred to as chronic congenital cytomegalic inclusion disease. Codes like P35.2 identify congenital herpes simplex infections, sometimes called perinatal herpes simplex. The section also includes codes for congenital viral hepatitis (P35.3) relating to hepatitis A, B, or C transmitted at birth, and congenital Zika virus disease (P35.4). Other less common viral infections are grouped under P35.8, while P35.9 is used when the congenital viral disease is unspecified. This categorization supports precise coding for newborn viral infections and related perinatal complications.
