About P07
P07 is the ICD-10-CM diagnosis code for disorders of newborn related to short gestation and low birth weight, not elsewhere classified. It belongs to block P05-P08 (disorders of newborn related to length of gestation and fetal growth) 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 4 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: P07.0 (newborn), P07.1 (newborn), P07.2 (newborn) and P07.3 ([other]).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
