Infections of cervix in pregnancy, third trimester

This code signifies a bacterial, viral, or fungal infection affecting the cervix during the third trimester of pregnancy. It encompasses conditions such as cervicitis, chlamydia, gonorrhea, or herpes simplex virus presenting in the final three months of gestation. The infection may be symptomatic or asymptomatic, but its presence necessitates specific management due to potential maternal and fetal risks.

Assign this code when documentation clearly indicates an infection of the cervix diagnosed in a pregnant patient during her third trimester (typically weeks 28 through delivery). Supporting documentation includes positive laboratory tests for specific pathogens (e.g., cultures, PCR), clinical signs of cervicitis (e.g., purulent discharge, cervical friability), or a physician's definitive diagnosis of cervical infection.

• Always confirm the trimester of pregnancy documented in the medical record.
• Code any specific infectious organism identified (e.g., B97.7 for human papillomavirus) as an additional diagnosis.
• Do not use this code for infections of the vagina or vulva; refer to codes within O23.4- for those conditions.
