Oth infect w sexl mode of transmiss comp preg, second tri

This code signifies a maternal infection acquired primarily through sexual contact, excluding HIV, syphilis, chlamydia, gonorrhea, and herpes, that is actively complicating a pregnancy in its second trimester. These infections can include conditions like trichomoniasis, human papillomavirus (HPV) infections, or bacterial vaginosis, when documented as impacting the pregnancy.

Use this code when the medical record clearly documents a sexually transmitted infection (STI), other than those with specific O98 codes, that is adversely affecting the pregnant patient during her second trimester. Documentation should specify the type of infection and its impact on the pregnancy, such as preterm labor risk or fetal complications.

• Always sequence this code after the primary obstetric code (e.g., O09.- for supervision of pregnancy).
• Ensure the documentation explicitly links the STI as a complication of the pregnancy, not just a co-occurring condition.
• Do not use this code for STIs that have their own specific O98 category codes (e.g., O98.1- for syphilis, O98.2- for gonorrhea, O98.4- for HIV).
