Maternal malignant neoplasms, traumatic injuries and abuse classifiable elsewhere but complicating pregnancy, childbirth and the puerperium (O9A)

The O9A ICD-10 codes are used to classify maternal conditions involving malignant cancers, traumatic injuries, and various forms of abuse that complicate pregnancy, childbirth, and the postpartum period. These codes help identify and document complications that arise in these critical maternal stages, ensuring appropriate medical care and accurate health records.

This section covers detailed codes for malignant neoplasms complicating pregnancy (including by trimester), childbirth, or the puerperium, facilitating precise classification of cancer-related pregnancy complications such as malignancy diagnosed during pregnancy. It also includes codes for injuries and poisoning during these periods, addressing complications from trauma, including conditions like traumatic injury to vulva or dislocation of the symphysis pubis. Additionally, the codes capture different types of abuse; physical, sexual, and psychological; that complicate pregnancy and related stages. For example, terms like "physical abuse complicating pregnancy" or "sexual abuse complicating childbirth" correspond directly to specific ICD-10 codes such as O9A.311 or O9A.42. This coding range aids medical professionals and coders in accurately documenting complex maternal health issues for optimal care and reporting.
