Alcohol use complicating pregnancy, unspecified trimester

This code identifies any adverse effects of alcohol consumption on a pregnant patient, regardless of the specific trimester, when the impact on the pregnancy is not further specified. It indicates a direct or indirect complication arising from alcohol use during gestation.

Apply this code when documentation clearly states alcohol use complicating the pregnancy, but the specific trimester is not recorded. This is appropriate for conditions such as fetal alcohol spectrum disorders (FASD) or other adverse maternal or fetal outcomes linked to alcohol exposure, where the trimester of exposure is unknown.

• Always seek documentation for the specific trimester if available; if so, a more specific O99.31x code should be used.
• Code also the specific alcohol-related disorder (e.g., F10.x for alcohol abuse/dependence) and any resulting fetal conditions (e.g., Q86.0 for Fetal Alcohol Syndrome).
• Do not use this code if the alcohol use is merely incidental and not documented as complicating the pregnancy.
