P04Newborn affected by noxious substances transmitted via placenta or breast milk

Non-billable headerICD-10-CM

P04 is a non-billable header ICD-10-CM code for newborn affected by noxious substances transmitted via placenta or breast milk. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • 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.-)

Code first

The underlying condition must be sequenced before this code.

  • any current condition in newborn, if applicable

Includes

Conditions this code covers.

  • nonteratogenic effects of substances transmitted via placenta

Other codes that can never be billed with P04

These codes carry an Excludes1 note pointing at P04. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P04 alone.

  • P93Reactions and intoxications due to drugs administered to newborn
  • P96.1Neonatal withdrawal symptoms from maternal use of drugs of addiction

Risk adjustment

P04 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 to one of these instead P04

9 child codes. Green means billable.
