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.
