Infct of amniotic sac and membrns, unsp, unsp tri, fetus 3

This code describes an infection of the amniotic sac and membranes, also known as chorioamnionitis, where the specific type of infection is not documented. It indicates that the trimester of pregnancy is unspecified, and the condition is affecting the third fetus in a multiple gestation pregnancy.

Use this code when documentation confirms chorioamnionitis in a multiple gestation pregnancy, specifically impacting the third fetus, but lacks details regarding the causative organism or the specific trimester of gestation. This code is appropriate when the provider notes "chorioamnionitis, unspecified" or similar terminology for the third fetus without further specification.

• Ensure documentation clearly identifies the infection as affecting the third fetus in a multiple gestation.
• Avoid using this code if the specific organism causing the infection or the trimester is documented; instead, use a more specific code.
• Always sequence this code after the primary obstetric code for the pregnancy.
