Placentitis, third trimester, fetus 3

This code signifies inflammation of the placenta occurring during the third trimester of pregnancy, specifically when the pregnancy involves a third fetus in a multiple gestation. Placentitis can be caused by infection or other inflammatory processes, potentially impacting fetal health and pregnancy outcomes.

Apply this code when documentation clearly indicates placentitis in a pregnant patient who is in her third trimester and is carrying triplets or more, with the condition specifically affecting the third fetus. Supporting documentation should include physician notes detailing the diagnosis of placentitis, the gestational age, and the specific fetus affected in a multiple gestation.

• Ensure the documentation specifies "third trimester" and clearly identifies the affected fetus as "fetus 3" in a multiple gestation.
• Do not use this code if the placentitis occurs in a different trimester or affects a different fetus.
• Always sequence this code after the primary obstetric code indicating the pregnancy.
