About P01

P01 is the ICD-10-CM diagnosis code for newborn affected by maternal complications of 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: P01.0 (cervix), P01.1 (membranes), P01.2 (oligohydramnios), P01.3 (polyhydramnios), P01.4 (pregnancy), P01.5 (pregnancy), P01.6 (death), P01.7 (labor) and 2 more.

The conditions in its Excludes2 note aren't part of P01, but may be coded alongside it if the patient has both: encounter for observation of newborn for suspected diseases and conditions ruled out (Z05.-).

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).
