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

This code signifies a maternal infection acquired primarily through sexual contact that is complicating a pregnancy, where the specific trimester is not documented. This includes conditions like chlamydia, gonorrhea, or trichomoniasis when they adversely affect the pregnant patient or the pregnancy itself.

Use this code when the medical record clearly indicates a sexually transmitted infection (STI) is complicating the pregnancy, but the specific trimester of pregnancy is not specified by the provider. Documentation should confirm the presence of an STI and its impact on the pregnancy.

• Always strive for more specific codes when the trimester is known (e.g., O98.311, O98.312, O98.313).
• Code the specific STI first, followed by this code to indicate the complication during pregnancy.
• Ensure the documentation explicitly states the STI is "complicating" the pregnancy, not just co-existing.
