P00Newborn affected by maternal conditions that may be unrelated to present pregnancy

P00 is the ICD-10-CM diagnosis code for newborn affected by maternal conditions that may be unrelated to present pregnancy. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: P00.0 (disorders), P00.1 (diseases), P00.2 (diseases), P00.3 (diseases), P00.4 (disorders), P00.5 (injury), P00.6 (mother), P00.7 (classified) and 2 more.

The conditions in its Excludes2 note aren't part of P00, but may be coded alongside it if the patient has both: encounter for observation of newborn for suspected diseases and conditions ruled out (Z05.-), newborn affected by maternal complications of pregnancy (P01.-), newborn affected by maternal endocrine and metabolic disorders (P70-P74) and newborn affected by noxious substances transmitted via placenta or breast milk (P04.-).

Code first: any current condition in newborn.

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