Alcohol use complicating pregnancy, second trimester

This code signifies the presence of alcohol use disorder or alcohol dependence in a pregnant patient during her second trimester, where the alcohol use is considered to be a complicating factor in the pregnancy. It indicates that the maternal alcohol consumption has a direct or indirect impact on the pregnancy's course or outcome.

Assign this code when documentation explicitly states alcohol use (abuse or dependence) in a pregnant patient and specifies the second trimester. This includes situations where alcohol use is being managed, is causing maternal health issues, or is a concern for fetal development during this specific gestational period.

• Ensure the medical record clearly documents "alcohol use" (not just "history of alcohol use") and the specific trimester.
• Do not use this code for a history of alcohol use if the patient is currently abstinent and it is not complicating the current pregnancy.
• Always sequence this code as a secondary diagnosis, following the code for the primary reason for the encounter (e.g., routine prenatal care).
