Placentitis, first trimester, fetus 5

This code signifies inflammation of the placenta occurring during the first trimester of pregnancy, specifically affecting the fifth fetus in a multiple gestation. Placentitis can be caused by various infections and may lead to adverse pregnancy outcomes.

Apply this code when documentation confirms placentitis in a multifetal pregnancy, with the condition identified in the first trimester and specifically attributed to the fifth fetus. Supporting documentation should include ultrasound findings, pathology reports, or clinical notes detailing the diagnosis and gestational age.

• Ensure the documentation clearly specifies "first trimester" and identifies the affected fetus as the fifth.
• Do not confuse with other placental conditions or infections of the amniotic fluid.
• Always sequence this code after the primary obstetric code indicating the pregnancy.
