Tuberculosis complicating pregnancy, first trimester

This code signifies the presence of active or latent tuberculosis (TB) in a pregnant patient during her first trimester. It indicates that the TB is considered a complication of the pregnancy, requiring specific management and monitoring due to the potential impact on both mother and fetus.

Apply this code when documentation confirms a diagnosis of tuberculosis (active or latent) in a pregnant patient who is specifically in her first trimester. Supporting documentation would include a confirmed TB diagnosis (e.g., positive culture, chest X-ray findings, PPD test results) and clear indication of the gestational period.

• Always sequence this code as a secondary diagnosis, following the code for the specific type of tuberculosis (e.g., A15-A19).
• Ensure the medical record explicitly states "first trimester" for accurate trimester-specific coding.
• Do not use this code if the tuberculosis is not documented as complicating the pregnancy.
