P04.1: Newborn affected by other maternal medication

Non-billable headerICD-10-CM

P04.1 is a non-billable header ICD-10-CM code for newborn affected by other maternal medication. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • dysmorphism due to warfarin (Q86.2)
  • fetal hydantoin syndrome (Q86.1)

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.

  • maternal anesthesia and analgesia in pregnancy, labor and delivery (P04.0)
  • maternal use of drugs of addiction (P04.4-)

Code first

The underlying condition must be sequenced before this code.

  • , if applicable, withdrawal symptoms from maternal use of drugs of addiction (P96.1)
  • withdrawal symptoms from therapeutic use of drugs in newborn (P96.2)

Excludes2 inherited from the categories above P04.1

Not part of this code, but both may be coded when both are present.

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.-)

Other codes that can never be billed with P04.1

Their own Excludes1 notes name this code, so the conflict is not listed above.

  • P93Reactions and intoxications due to drugs administered to newborn
