Short answer · Medically reviewed summary · Last updated: 2026-05-08
The medical classification for Kernicterus is defined by the ICD-10 code P57.9 (Kernicterus, unspecified) and the ICD-9 code 773.4. These codes are used by healthcare providers and insurers to document this specific form of bilirubin-induced brain dysfunction in clinical records. What is the clinical significance of Kernicterus? Kernicterus is a rare, preventable neurological condition that occurs when high levels of unconjugated bilirubin in the blood cross the blood-brain barrier, causing permanent damage to the basal ganglia and brainstem.

The medical classification for Kernicterus is defined by the ICD-10 code P57.9 (Kernicterus, unspecified) and the ICD-9 code 773.4. These codes are used by healthcare providers and insurers to document this specific form of bilirubin-induced brain dysfunction in clinical records.
What is the clinical significance of Kernicterus?
Kernicterus is a rare, preventable neurological condition that occurs when high levels of unconjugated bilirubin in the blood cross the blood-brain barrier, causing permanent damage to the basal ganglia and brainstem. While jaundice is common in newborns, Kernicterus represents the severe, chronic phase of bilirubin encephalopathy. Early identification and management of hyperbilirubinemia are critical to preventing the long-term motor and auditory impairments associated with Kernicterus.
How are the ICD codes for Kernicterus used?
Medical coding, such as the ICD-10 code P57.9, is essential for hospital billing, tracking public health statistics, and facilitating research. Because Kernicterus can result in lifelong disabilities, accurate coding ensures that patients receive the appropriate level of care and support services. In the DiseaseMaps.org community, 146 members have shared their experiences, highlighting the importance of standardized documentation to better understand the long-term outcomes of this condition.
What are the common clinical features of Kernicterus?
When bilirubin levels remain dangerously high, the damage to the central nervous system can manifest in several ways. Common clinical features observed in individuals with Kernicterus include:
- Athetosis: Involuntary, slow, writhing movements of the limbs.
- Auditory Neuropathy: Sensorineural hearing loss or auditory processing deficits.
- Oculomotor Impairment: Difficulty with upward gaze or other eye movement abnormalities.
- Dental Enamel Dysplasia: Abnormal development of the tooth enamel.
