Pregnancy, childbirth and the puerperium (O00-O9A)

ICD-10-CM Chapter 15 (O00-O9A) covers all conditions related to pregnancy, childbirth, and the postpartum period. These codes are used to document maternal health from conception through delivery and recovery.

This chapter includes codes for complications during pregnancy such as ectopic pregnancy, gestational diabetes, and preeclampsia. It also addresses labor and delivery details, including normal delivery, cesarean sections, and complications arising during birth. Additionally, the codes cover the postpartum period, known as the puerperium, which involves monitoring and managing health issues following childbirth. Healthcare providers and coders use this set to capture the medical conditions and care specific to pregnancy and childbirth, ensuring accurate tracking of maternal health events and related treatments.
