Premature separation of placenta [abruptio placentae] (O45)

ICD-10 codes in the O45 series are used to classify various forms of premature separation of the placenta, commonly known as abruptio placentae. These codes capture whether the condition occurs with or without coagulation defects and specify the trimester when it happens, providing important detail for diagnosis and treatment.

These codes help identify cases of placental abruption occurring alongside clotting disorders such as afibrinogenemia, disseminated intravascular coagulation, or other coagulation defects, allowing precise tracking of complications. For example, O45.0 covers placental separation with coagulation defect, while specific subcodes like O45.001 or O45.022 denote the trimester involved. Additionally, unspecified versions like O45.90 cover cases where trimester or additional details are not provided. Common terms such as placental abruption, antepartum hemorrhage, or bleeding from female genital tract during pregnancy are linked to these codes, assisting both the public and medical coders in pinpointing the exact diagnosis and appropriate code.
