P04.8 is a non-billable header ICD-10-CM code for newborn affected by other maternal noxious substances. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above P04.8
Also inherited, and the opposite of Excludes1: these conditions are not part of P04.8, but a patient can have both, so you may code both.
Written on P04 — Newborn affected by noxious substances transmitted via placenta or breast milk
- congenital malformations (Q00-Q99)
- encounter for observation of newborn for suspected diseases and conditions ruled out (Z05.-)
- neonatal jaundice from excessive hemolysis due to drugs or toxins transmitted from mother (P58.4)
- newborn in contact with and (suspected) exposures hazardous to health not transmitted via placenta or breast milk (Z77.-)
Risk adjustment
P04.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
P04.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
