Oth maternal infec/parastc diseases comp preg, second tri

This code signifies any infectious or parasitic disease, other than those specifically classified elsewhere (e.g., HIV, syphilis, gonorrhea), that is present during pregnancy and adversely affecting the mother's health or the pregnancy outcome during the second trimester. These conditions can range from viral infections like influenza or varicella to parasitic infestations, provided they are not explicitly coded under other O98 subcategories.

Use this code when documentation clearly indicates a maternal infectious or parasitic disease, not otherwise specified, that is complicating a pregnancy in the second trimester. This applies to conditions like a significant urinary tract infection, pneumonia, or a parasitic infection that requires medical management and is documented as impacting the pregnancy. The medical record must specify the trimester and the nature of the infection.

• Always ensure the documentation specifies "second trimester" for accurate coding.
• Do not use this code for infections with specific O98 subcategories (e.g., O98.0-O98.7).
• Code the specific infectious or parasitic disease first, followed by this code as a secondary diagnosis to indicate the complication of pregnancy.
