Hemolytic disease of newborn, unspecified

This code represents a condition in a newborn where red blood cells are destroyed prematurely due to an immune response, leading to anemia and hyperbilirubinemia. It signifies a general diagnosis of hemolytic disease of the newborn without further specification of the cause or type.

Use this code when documentation confirms a diagnosis of hemolytic disease in a newborn, but the specific etiology (e.g., Rh incompatibility, ABO incompatibility, G6PD deficiency) is not identified or documented. This code is appropriate when the medical record simply states "hemolytic disease of newborn" without further detail.

• Avoid using this code if a more specific type of hemolytic disease (e.g., due to Rh isoimmunization, ABO isoimmunization) is documented.
• Always query for more specific documentation if "hemolytic disease of newborn" is noted without further detail.
• Consider sequencing with codes for associated conditions like neonatal jaundice (P59.-) or hydrops fetalis (P83.2) if present.
