19
chapter
Certain conditions originating in the perinatal period
Definition
This chapter includes conditions that have their origin in the perinatal period even though death or morbidity occurs later.
Coding note
Conditions arising in the perinatal period, even though death or morbidity occurs later, should, as far as possible, be coded to chapter 19, which takes precedence over chapters containing codes for diseases by their anatomical site. For children less than 28 days old, assume that a reported condition developed in the perinatal period, unless the duration is stated and the onset was after the first completed week of life.
