P57 vs P59

P57 (Kernicterus) compared with P59 (Neonatal jaundice from other and unspecified causes), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.

Can these codes be reported together?

No — do not report together. P59 carries an Excludes1 note covering P57: “kernicterus (P57.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
