About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Cesarean Delivery
A cesarean delivery, also called a cesarean section or c-section, is surgery to deliver a baby. The baby is taken out through your abdomen (belly). In the United States, almost one in three babies are born this way. Some cesarean deliveries are planned. Others are emergency cesarean deliveries, which are done when unexpected problems happen during delivery.
