Diseases of the resp sys comp pregnancy, third trimester

This code signifies a pre-existing or new respiratory system disease that adversely affects a pregnant patient during her third trimester. This includes conditions such as asthma, bronchitis, pneumonia, or other lung disorders that complicate the pregnancy. The respiratory condition may impact maternal and fetal health outcomes.

Apply this code when a pregnant patient in her third trimester presents with a respiratory illness that is documented as complicating the pregnancy. This requires physician documentation explicitly linking the respiratory disease to the pregnancy's course. Examples include a pregnant patient with an asthma exacerbation requiring hospitalization in her 30th week, or a new diagnosis of pneumonia at 32 weeks gestation.

• Always sequence the primary respiratory condition code first, followed by this code.
• Ensure documentation specifies "third trimester" and a clear link between the respiratory disease and the pregnancy.
• Do not use this code if the respiratory condition is unrelated to the pregnancy or if the patient is not in her third trimester.
