P57.0
BillableKernicterus due to isoimmunization
HCC Category Mapping
V28HCC 192 — Cerebral Palsy, Except Quadriplegic
0.368What This Code Means
Brain damage in newborns caused by high levels of bilirubin (a yellow pigment from broken-down red blood cells) resulting from blood type incompatibility between mother and baby.
Coding Tips
- •Kernicterus is a serious complication; ensure bilirubin levels and timing of onset are documented to support medical necessity
- •Link this code to the underlying isoimmunization cause (Rh, ABO, etc.) for complete clinical picture
Clinical Significance
Kernicterus due to isoimmunization represents severe brain damage from bilirubin toxicity secondary to maternal-fetal blood incompatibility, resulting in permanent neurological sequelae including cerebral palsy and hearing loss. This condition represents a preventable but devastating complication requiring immediate recognition and aggressive treatment.
Documentation Requirements
- ✓Documentation of severe hyperbilirubinemia with neurological symptoms
- ✓Evidence of maternal-fetal blood group incompatibility
- ✓Clinical signs of bilirubin encephalopathy (lethargy, poor feeding, seizures)
- ✓Extremely elevated serum bilirubin levels
- ✓Neurological examination findings consistent with kernicterus
- ✓Imaging studies showing brain changes when available
- ✓Treatment history including exchange transfusion attempts
- ✓Long-term neurological outcome documentation
