About P57

P57 is the ICD-10-CM diagnosis code for kernicterus. It belongs to block P50-P61 (hemorrhagic and hematological disorders of newborn) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P57.0 (due to isoimmunization), P57.8 (kernicterus) and P57.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
