Certain conditions originating in the perinatal period is a chapter in ICD-11 that includes disorders arising during pregnancy, childbirth, or the early neonatal period that affect the health and development of the newborn. These conditions are often linked to maternal health, placental function, birth processes, or early adaptation to extrauterine life, and may have short-term or long-term consequences for infant survival and development.
This chapter covers a range of conditions such as complications of prematurity, birth trauma, respiratory and cardiovascular disorders specific to the perinatal period, and infections acquired before or during birth. Accurate classification supports neonatal care, early intervention, outcome monitoring, and public health efforts aimed at reducing perinatal morbidity and mortality.
