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

This code signifies an infection of the amniotic sac and membranes (chorioamnionitis) occurring during the second trimester of pregnancy. The specific type of infection is not documented or is unspecified. This condition can lead to significant maternal and fetal complications.

This code is appropriate when documentation confirms chorioamnionitis in a pregnant patient in her second trimester, and the causative organism or specific type of infection is not identified. It should be used when the medical record clearly indicates an infection of the amniotic fluid and surrounding membranes without further specificity.

• Ensure the trimester is clearly documented as the second trimester.
• Do not use this code if a specific infectious agent (e.g., bacterial, viral) is identified; instead, use a more specific code from the O41.1- series.
• Always sequence this code as a principal diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity affecting the pregnancy.
