Other specified kernicterus

This code signifies brain damage in a newborn due to severe, untreated jaundice, specifically when the bilirubin-induced encephalopathy doesn't fit the typical presentation of kernicterus. It indicates neurological dysfunction resulting from high levels of unconjugated bilirubin crossing the blood-brain barrier.

Utilize this code when documentation specifies kernicterus with atypical features or when the specific type of kernicterus is not otherwise classifiable to a more specific code. Supporting documentation should detail neurological signs (e.g., hypotonia, seizures, high-pitched cry) in an infant with a history of hyperbilirubinemia.

• Ensure the documentation clearly states "kernicterus" or "bilirubin encephalopathy" and specifies it as "other" or "atypical."
• Do not code this with Crigler-Najjar syndrome (E80.5) as per the Excludes1 note; these conditions are mutually exclusive.
• Always sequence this code after the underlying cause of the hyperbilirubinemia (e.g., hemolytic disease of newborn, prematurity) if known.
