Diseases of the dgstv sys comp pregnancy, second trimester

This code signifies a maternal digestive system disorder that arises or is exacerbated during the second trimester of pregnancy. It encompasses conditions such as appendicitis, cholecystitis, inflammatory bowel disease, or severe gastroenteritis that directly impact the pregnant patient's health during this specific gestational period.

Apply this code when documentation clearly indicates a pre-existing or newly diagnosed digestive system disease is complicating a pregnancy in its second trimester. Supporting documentation would include physician notes detailing the specific digestive condition, its impact on the pregnancy, and the gestational age at the time of diagnosis or exacerbation.

• Always sequence the obstetric code (from category O09-O9A) as the primary diagnosis, followed by this code.
• Ensure the documentation specifies "second trimester" to justify using this particular trimester-specific code.
• Do not use this code for digestive conditions unrelated to the pregnancy or those occurring in other trimesters.
