Infct of amniotic sac and membrns, unsp, first tri, unsp

This code signifies an infection of the amniotic sac and membranes (chorioamnionitis) occurring during the first trimester of pregnancy. The specific type of infection is not identified, and the laterality (e.g., single vs. multiple gestation) is also unspecified or not applicable.

Use this code when documentation confirms a diagnosis of chorioamnionitis in a pregnant patient during her first trimester, and the specific infectious agent is not documented. This code is appropriate when the medical record does not specify if the pregnancy involves a single or multiple fetus.

• Ensure the documentation clearly states "first trimester" for the timing of the infection.
• Do not use this code if a specific infectious organism is identified; instead, code the specific infection.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
