Alcohol use complicating pregnancy, third trimester

This code signifies the presence of alcohol use by a pregnant patient during her third trimester, which is considered a complication of the pregnancy. It indicates that the alcohol use is impacting or has the potential to impact the course or outcome of the pregnancy or the fetus.

Apply this code when documentation clearly indicates a pregnant patient's alcohol use specifically occurring in the third trimester. This includes both current use and conditions arising from past use that are still relevant during this period. Documentation should specify the trimester or a date range falling within the third trimester.

• Always sequence this code as a secondary diagnosis, following the code for the obstetric condition.
• Ensure documentation specifies "third trimester" or provides dates that confirm the third trimester. Do not assume the trimester if not explicitly stated.
• Distinguish from codes for alcohol dependence or abuse without the specific third-trimester complication.
