About P07.3
P07.3 is the ICD-10-CM diagnosis code for preterm [premature] newborn [other]. It belongs to category P07 (disorders of newborn related to short gestation and low birth weight, not elsewhere classified), 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 10 subcodes must be used instead.
Within P07, choose P07.3 (Preterm [premature] newborn [other]) only when documentation doesn't support a more specific option: Extremely low birth weight newborn (P07.0), other low birth weight newborn (P07.1) and extreme immaturity of newborn (P07.2).
To report this condition, pick the subcode that matches the documentation: P07.30 (gestation), P07.31 (weeks), P07.32 (weeks), P07.33 (weeks), P07.34 (weeks), P07.35 (weeks), P07.36 (weeks), P07.37 (weeks) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
