Hemorrhagic disease of newborn

This code represents a bleeding disorder in a neonate, typically caused by a deficiency of vitamin K-dependent clotting factors. It manifests as spontaneous or excessive bleeding, often affecting the gastrointestinal tract, skin, or intracranial spaces. This condition is distinct from other causes of neonatal hemorrhage.

Use this code when documentation clearly indicates a diagnosis of hemorrhagic disease of the newborn, often supported by laboratory findings of prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT) that correct with vitamin K administration. This diagnosis is typically made in the first few weeks of life.

• Differentiate from other neonatal bleeding disorders, such as thrombocytopenia or disseminated intravascular coagulation (DIC).
• Ensure documentation specifies "of newborn" to distinguish from hemorrhagic disease in older individuals.
• Consider sequencing with codes for specific bleeding sites if documented (e.g., intracranial hemorrhage).
