About P05

P05 is the ICD-10-CM diagnosis code for disorders of newborn related to slow fetal growth and fetal malnutrition. 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: P05.0 (age), P05.1 (age), P05.2 (age) and P05.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
