Tuberculosis complicating pregnancy, second trimester

This code signifies a diagnosis of active or latent tuberculosis (TB) occurring in a pregnant patient during her second trimester. It indicates that the TB infection is considered a complication of the pregnancy, potentially impacting both maternal and fetal health.

Use this code when a pregnant patient in her second trimester is diagnosed with tuberculosis. Documentation should clearly state the presence of TB and the gestational age or trimester at the time of diagnosis or active management. This code is appropriate for both new diagnoses and exacerbations of pre-existing TB during this specific trimester.

• Always code the specific type of tuberculosis (e.g., A15.-, A16.-, A17.-, A18.-, A19.-) as a secondary diagnosis to provide full clinical detail.
• Ensure the medical record explicitly states "second trimester" or provides gestational weeks (e.g., 14-27 weeks) to support this trimester-specific code.
• Do not use this code if the TB is not considered a complication of the pregnancy; instead, code the TB and the pregnancy separately.
