Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 code O30.813 refers to a specific pregnancy condition where a woman carries multiple fetuses that share the same chorion—meaning they are monochorionic—in the third trimester of pregnancy. Multiple gestations are pregnancies with more than one fetus, and monochorionic pregnancies involve fetuses sharing the same placenta. This condition requires careful monitoring due to unique risks and complications associated with shared placental resources.
Causes & Symptoms
Clinical Causes: Genetic factors that influence multiple ovulations Inheritance factors increasing the likelihood of multiple pregnancies Certain fertility treatments that stimulate ovulation Natural conception, although less common in monochorionic pregnancies No specific environmental or lifestyle factors are directly linked to monochorionic multiple pregnancies
Key Symptoms: Typically, no specific symptoms are caused solely by the monochorionic nature of the pregnancy Possible signs of complications such as abnormal fetal growth or discrepancies in fetal size Polyhydramnios or excess amniotic fluid may be noted Signs of preterm labor or early labor symptoms Ultrasound findings revealing shared placental circulation and multiple fetuses sharing the same chorion
Diagnostic & Treatment
Diagnosis Path: - Serial ultrasounds to monitor fetal growth and well-being throughout the third trimester
Treatment Protocols: - Delivery methods primarily include cesarean section if indicated to minimize risks during birth
