Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the O44 range.
Placenta Previa
Abnormal placentation in which the PLACENTA implants in the lower segment of the UTERUS (the zone of dilation) and may cover part or all of the opening of the CERVIX. It is often associated with serious antepartum bleeding and PREMATURE LABOR.
Postpartum Hemorrhage
Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).
About the O44 Code Range
ICD-10 code O44 covers various types of placenta previa, a condition where the placenta partially or completely covers the cervix, potentially leading to bleeding during pregnancy. The codes differentiate between complete, partial, and low-lying placenta previa, with additional specification by trimester and presence or absence of hemorrhage.
The ICD-10 code for placenta previa is used to classify this placental placement disorder in pregnant patients, helping healthcare providers document the severity and timing of complications. Subcodes like O44.00 refer to complete placenta previa without hemorrhage in an unspecified trimester, while O44.10 describes complete placenta previa with hemorrhage. These codes also account for partial types such as O44.20 (partial placenta previa without hemorrhage) and low-lying placenta cases like O44.40. Synonyms such as “placenta previa centralis” and “placenta previa marginalis” correspond to specific codes, aiding in accurate coding for conditions like postpartum hemorrhage or antepartum bleeding linked to placenta previa. This classification ensures clear documentation tailored to the placenta’s location and bleeding status across pregnancy trimesters.
