Pregnancy, childbirth and the puerperium

This chapter applies specifically to maternal records and includes conditions related to pregnancy, labor, delivery, and the postpartum period (puerperium). It does not apply to the newborn; neonatal conditions are coded separately in the P chapter. Codes are highly specific and often require trimester identification. The chapter includes ectopic pregnancy, spontaneous abortion, complications of pregnancy (such as hyperemesis gravidarum), gestational diabetes, hypertensive disorders (like preeclampsia), and complications during labor and delivery.
It also includes postpartum complications such as infections, hemorrhage, and cardiomyopathy. Many codes require additional details, such as single vs. multiple gestation and outcome of delivery. This chapter is crucial for obstetric care documentation, maternal health tracking, and public health reporting. Because maternal outcomes are key quality indicators globally, precise coding is essential for monitoring complications and improving perinatal care systems.
