Placenta percreta, first trimester

This code signifies a severe form of placental invasion where the chorionic villi penetrate through the entire uterine wall and invade adjacent organs, such as the bladder or bowel, occurring specifically during the first trimester of pregnancy. This condition carries a high risk of maternal morbidity and mortality due to potential hemorrhage and organ damage.

Apply this code when documentation clearly indicates a diagnosis of placenta percreta in a pregnant patient during her first trimester. This diagnosis is typically confirmed through imaging studies (e.g., ultrasound, MRI) and/or surgical findings. The medical record must explicitly state the "percreta" degree of invasion and the "first trimester" timeframe.

• Ensure documentation explicitly differentiates between placenta accreta, increta, and percreta; this code is specific to percreta.
• Verify the gestational age at the time of diagnosis to confirm it falls within the first trimester (up to 13 weeks and 6 days).
• Code any associated complications, such as hemorrhage or organ involvement, in addition to this code.
