Diseases of the dgstv sys comp pregnancy, third trimester

This code signifies the presence of a pre-existing or new digestive system disorder that is adversely affecting a pregnancy during the third trimester. This includes conditions such as inflammatory bowel disease, cholelithiasis, appendicitis, or severe gastroesophageal reflux disease, which are impacting maternal or fetal health due to the pregnancy.

Apply this code when a pregnant patient in her third trimester is diagnosed with a digestive system disease that is either exacerbated by the pregnancy or directly complicates its course. Documentation should clearly link the digestive condition to the pregnancy, indicating its impact on management or outcome.

• Always sequence this code as a secondary diagnosis, following the primary obstetric code (e.g., O80-O82, O09-O09.93).
• Ensure the medical record specifies the trimester of pregnancy; this code is specific to the third trimester.
• Do not use for digestive conditions that are incidental to pregnancy and do not complicate it.
