About the O00–O08 Code Range
ICD-10 codes O00 through O08 cover conditions related to pregnancy with abortive outcomes, including ectopic pregnancies, molar pregnancies, spontaneous abortions (miscarriages), and complications following induced abortion or failed termination attempts. These codes help specify the type of pregnancy loss or complication for accurate diagnosis and treatment.
The range begins with O00 codes for various types of ectopic pregnancy, such as abdominal pregnancy (O00.00), tubal pregnancy (O00.10), and ovarian pregnancy (O00.20), often referred to as tubal, ruptured tubal, or intraperitoneal pregnancies. Codes O01 and O02 address molar pregnancies (also called hydatidiform mole or gestational trophoblastic disease) and other abnormal products of conception like blighted ovum or missed abortion. The O03 series focuses on spontaneous abortions, detailing complications including infection, hemorrhage, embolism, shock, or organ damage following miscarriage. Separate codes O04 and O07 specify complications from induced termination of pregnancy or failed attempts, encompassing infection, hemorrhage, embolism, and shock. Finally, O08 codes describe sequelae after ectopic or molar pregnancies, including infection, hemorrhage, renal failure, metabolic disorders, venous complications, and cardiac arrest. These codes are essential for identifying specific causes and complications following early pregnancy loss or termination.
