Neonatal kernicterus

Description

Kernicterus is a pathologic diagnosis of the neonate that is characterised by yellow staining of the basal ganglia following elevated bilirubin concentrations in the blood and/or a breech in the blood brain barrier more common in the premature infant or the sick term neonate. It is characterised later in infancy and childhood by hearing deficits, choreoathetosis, and varying degrees of cognitive deficit.

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.
