Other specified congenital infectious and parasitic diseases

This code represents congenital infectious or parasitic diseases that are not specifically classified elsewhere in the P37 category. These are conditions acquired by the fetus or newborn from the mother during pregnancy or childbirth, resulting from an infection or parasitic infestation. It covers a range of rare or less common congenital infections with identifiable pathogens.

Use this code when documentation clearly indicates a congenital infectious or parasitic disease in a newborn that is not covered by more specific codes within P37 (e.g., congenital toxoplasmosis, rubella, cytomegalovirus, herpes, syphilis). Supporting documentation should specify the infectious agent or parasitic infestation and confirm its congenital origin.

• Always attempt to code to a more specific P37 subcategory if the documentation allows.
• Ensure the medical record explicitly states the infection or parasitic disease is congenital.
• Do not use this code for infections acquired post-natally; those would be coded to Chapter A or B codes.
