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

This code signifies an infection of the amniotic fluid and surrounding membranes (chorioamnionitis) occurring during the second trimester of pregnancy, where the specific type of infection is not documented. It pertains to a multifetal pregnancy, with the infection affecting a fetus other than the first-listed one.

Use this code when documentation confirms chorioamnionitis in a multifetal pregnancy during the second trimester, and the specific infectious agent is unknown. The medical record must clearly indicate that the infection is present in a fetus other than the designated "first" fetus.

• Ensure the trimester (second) and the affected fetus (other) are clearly documented.
• Do not use if a specific infectious organism is identified; instead, code to the specific infection.
• This code is for an unspecified infection; if the infection is specified, a more precise code should be used.
