2025 ICD-10-CM code O43.231

Placenta percreta, first trimester.This condition involves an abnormally deep attachment of the placenta to the uterine wall, penetrating through the endometrium and myometrium, and sometimes even into nearby organs, during the first trimester of pregnancy.

Use additional code from category Z3A, Weeks of gestation, to identify the specific week of the pregnancy, if known. Code also: associated third stage postpartum hemorrhage, if applicable (O72.0).

Placenta percreta is a serious pregnancy complication that can lead to life-threatening hemorrhage during delivery.Medical necessity for treatment, which often involves a cesarean hysterectomy to control bleeding, is directly related to preserving maternal health.

Obstetricians and maternal-fetal medicine specialists are primarily responsible for diagnosing and managing placenta percreta.This involves careful monitoring, planning for delivery, which usually requires a cesarean hysterectomy, and providing appropriate postpartum care.

In simple words: The placenta, which nourishes the baby during pregnancy, has grown too deeply into the mother's uterine wall in the first trimester (first 3 months).

Placenta percreta is an obstetric complication in which the placenta attaches abnormally deeply into the uterine wall, extending through the endometrium and myometrium, and potentially invading adjacent organs such as the bladder.This specific code denotes this dangerous condition's presence during the first trimester (less than 14 weeks 0 days) of pregnancy.

Example 1: A pregnant woman at 12 weeks gestation undergoes an ultrasound which reveals placenta percreta with invasion into the bladder wall., A patient with a history of previous cesarean sections presents with heavy vaginal bleeding at 10 weeks gestation, and an MRI confirms placenta percreta., During a first-trimester prenatal checkup, the physician suspects placenta percreta due to an abnormally elevated placental location and orders further imaging for confirmation.

Documentation should include ultrasound or MRI findings confirming the diagnosis, details about the depth of placental invasion, involvement of adjacent organs, and any associated complications like bleeding or pain.The gestational age, based on the last menstrual period, should also be clearly documented.
