About P04.1

P04.1 is the ICD-10-CM diagnosis code for newborn affected by other maternal medication. It belongs to category P04 (newborn affected by noxious substances transmitted via placenta or breast milk), block P00-P04 (newborn affected by maternal factors and by complications of pregnancy, labor, and delivery) 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 10 subcodes must be used instead.

Within P04, choose P04.1 (other maternal medication) only when documentation doesn't support a more specific option: maternal anesthesia and analgesia in pregnancy, labor and delivery (P04.0), maternal use of tobacco (P04.2), maternal use of alcohol (P04.3), maternal use of drugs of addiction (P04.4), maternal use of nutritional chemical substances (P04.5), maternal exposure to environmental chemical substances (P04.6), other maternal noxious substances (P04.8) and maternal noxious substance, unspecified (P04.9).

To report this condition, pick the subcode that matches the documentation: P04.11 (chemotherapy), P04.12 (drugs), P04.13 (anticonvulsants), P04.14 (opiates), P04.15 (antidepressants), P04.16 (amphetamines), P04.17 (sedative-hypnotics), P04.18 (medication) and 2 more.

Don't report P04.1 together with the conditions in its Excludes1 note: dysmorphism due to warfarin (Q86.2) and fetal hydantoin syndrome (Q86.1).

The conditions in its Excludes2 note aren't part of P04.1, but may be coded alongside it if the patient has both: maternal anesthesia and analgesia in pregnancy, labor and delivery (P04.0) and maternal use of drugs of addiction (P04.4-).

Code first: , if applicable, withdrawal symptoms from maternal use of drugs of addiction (P96.1), withdrawal symptoms from therapeutic use of drugs in newborn (P96.2) and any current condition in newborn, if applicable.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised) and FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 760.74 (anti-infectives affecting fetus or newborn via placenta or breast milk) and 760.78 (Antimetabolic agents affecting fetus or newborn via placenta or breast milk).
