Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the P57 range.
Kernicterus
A term used pathologically to describe BILIRUBIN staining of the BASAL GANGLIA; BRAIN STEM; and CEREBELLUM and clinically to describe a syndrome associated with HYPERBILIRUBINEMIA. Clinical features include athetosis, MUSCLE SPASTICITY or hypotonia, impaired vertical gaze, and DEAFNESS. Nonconjugated bilirubin enters the brain and acts as a neurotoxin, often in association with conditions that impair the BLOOD-BRAIN BARRIER (e.g., SEPSIS). This condition occurs primarily in neonates (INFANT, NEWBORN), but may rarely occur in adults. (Menkes, Textbook of Child Neurology, 5th ed, p613)
Kernicterus Related to Isoimmunization
Encephalopathy in infants due to high levels of unconjugated bilirubin that are a result of Rh incompatibility between the mother and the fetus.
About the P57 Code Range
Kernicterus primarily affects newborns and involves bilirubin entering the brain, where it acts as a toxin.
The subdivisions distinguish kernicterus due to isoimmunization (P57.0), other specified kernicterus (P57.8), and kernicterus without a specified type (P57.9).
