T67.4XXA Initial Encounter or T67.4XXD Subsequent Encounter. More Info
The ICD code O411 is used to code Chorioamnionitis
Chorioamnionitis also known as intra-amniotic infection (IAI) is an inflammation of the fetal membranes (amnion and chorion) due to a bacterial infection. It typically results from bacteria ascending into the uterus from the vagina and is most often associated with prolonged labor. The risk of developing chorioamnionitis increases with each vaginal examination that is performed in the final month of pregnancy, including during labor.
