Hemorrhagic disease of newborn

This code represents a bleeding disorder in a newborn infant caused by a deficiency of vitamin K-dependent clotting factors (II, VII, IX, X). It can manifest as early, classical, or late-onset bleeding, ranging from mild bruising to severe intracranial hemorrhage. The condition is preventable with prophylactic vitamin K administration at birth.

Use this code when documentation clearly indicates a diagnosis of hemorrhagic disease of the newborn, often presenting with unexplained bleeding in an infant who did not receive adequate vitamin K prophylaxis. Supporting documentation would include clinical signs of hemorrhage, laboratory findings consistent with coagulopathy (e.g., prolonged PT/aPTT), and a history of absent or insufficient vitamin K administration.

• Ensure documentation specifies "newborn" to differentiate from other vitamin K deficiency bleeding in older individuals.
• Do not confuse with other neonatal bleeding disorders not directly related to vitamin K deficiency.
• Consider sequencing this code as the principal diagnosis if it is the primary reason for admission or encounter.
