Protozoal diseases complicating pregnancy, unsp trimester

This code signifies the presence of a protozoal infection, such as malaria, toxoplasmosis, or trichomoniasis, occurring during any stage of pregnancy. It indicates that the protozoal disease is considered a complication of the pregnancy itself, potentially impacting maternal or fetal health. The specific trimester is not documented or is unknown.

Use this code when a pregnant patient is diagnosed with a protozoal disease, and the medical record indicates that this infection is complicating the pregnancy. This code is appropriate when the documentation does not specify the trimester of pregnancy or when the infection is present throughout the pregnancy without a clear trimester-specific onset.

• Always sequence this code after the code for the specific protozoal disease (e.g., B50-B64 for malaria, B58 for toxoplasmosis).
• Avoid using this code if a more specific code for the protozoal disease complicating a specified trimester is available (e.g., O98.611, O98.612, O98.613).
• Ensure documentation clearly links the protozoal infection as a complication of the pregnancy, not just a co-occurring condition.
