Kernicterus, unspecified

This code signifies brain damage in a newborn due to severe untreated jaundice, where the specific type of kernicterus is not documented. It results from high levels of bilirubin in the infant's blood, leading to neurological dysfunction. The condition can cause cerebral palsy, hearing loss, vision problems, and intellectual disabilities.

Assign this code when documentation confirms a diagnosis of kernicterus but lacks specificity regarding the exact clinical presentation or underlying cause. This is appropriate when the physician's diagnosis explicitly states "kernicterus, unspecified" or when the medical record details symptoms consistent with kernicterus without further classification.

• Always seek clarification from the provider if a more specific type of kernicterus (e.g., due to isoimmunization, prematurity) is suspected but not documented.
• Sequence this code after the underlying cause of the hyperbilirubinemia, if known and still active.
• Do not use this code for hyperbilirubinemia without evidence of brain damage.
