Bariatric surgery status comp pregnancy, unsp trimester

This code signifies a pregnancy complicated by a patient's history of bariatric surgery, where the specific trimester of pregnancy is not documented. It indicates that the previous weight loss surgery is a relevant factor in the current pregnancy management, potentially impacting maternal or fetal health.

Use this code when a pregnant patient has a documented history of bariatric surgery (e.g., gastric bypass, sleeve gastrectomy) and this history is noted as complicating the current pregnancy, but the trimester is not specified. Documentation should clearly link the bariatric surgery status to the pregnancy and its management.

• Always sequence this code as a secondary diagnosis, following the code for the primary obstetric condition.
• If the trimester is known and documented, use the more specific O99.84- code (O99.841, O99.842, O99.843).
• Ensure documentation explicitly states the bariatric surgery is "complicating" the pregnancy, rather than just a historical fact.
