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

This code signifies a maternal infection acquired primarily through sexual contact, occurring during the first trimester of pregnancy, that is causing complications. This includes conditions like chlamydia, gonorrhea, syphilis, or trichomoniasis when they adversely affect the pregnancy.

Apply this code when a pregnant patient in her first trimester is diagnosed with a sexually transmitted infection (STI) that is documented as complicating the pregnancy. Documentation should clearly state the specific STI and its impact or potential impact on the pregnancy.

• Always sequence this code after the specific STI code (e.g., A53.9 for syphilis, unspecified).
• Ensure the medical record explicitly links the STI to a complication of pregnancy.
• Verify the trimester of pregnancy; this code is specific to the first trimester.
