Neonatal vitamin K deficiency

Description

There are 3 forms of vitamin K–deficiency bleeding (VKDB) of the newborn. Early VKDB (haemorrhagic disease of the newborn) that occurs at 1-14 days of age. The most common sites of bleeding are the gastrointestinal tract, mucosal and cutaneous tissue, the umbilical stump, and the post-circumcision site. Late VKDB most commonly occurs at 2-12 weeks of age, although cases can occur up to 6 months. The most common site of bleeding is intracranial, although cutaneous and gastrointestinal bleeding may be initial manifestation. The third form of VKDB occurs at birth or shortly thereafter. It is secondary to maternal intake of medications (warfarin, phenobarbital, phenytoin) that cross the placenta.

Coding note from above levels

Conditions arising in the perinatal period, even though death or morbidity occurs later, should, as far as possible, be coded to chapter 19, which takes precedence over chapters containing codes for diseases by their anatomical site. For children less than 28 days old, assume that a reported condition developed in the perinatal period, unless the duration is stated and the onset was after the first completed week of life.
