Other viral diseases complicating pregnancy, first trimester

This code signifies the presence of a viral infection, other than those specifically classified elsewhere (e.g., HIV, hepatitis, rubella), that is complicating a pregnancy during the first trimester. It indicates that the viral disease is impacting the course of the pregnancy or the health of the pregnant patient.

Apply this code when a pregnant patient in her first trimester is diagnosed with a viral illness (e.g., influenza, parvovirus B19, cytomegalovirus) that is documented as complicating the pregnancy. Documentation should clearly state both the viral disease and its adverse effect or potential risk to the pregnancy.

• Always sequence the code for the specific viral disease first, followed by this code.
• Ensure the medical record explicitly links the viral disease as a complication of pregnancy.
• Verify the trimester of pregnancy documented to ensure it aligns with "first trimester."
