In simple words: This code indicates digestive problems affecting a pregnant woman in her first trimester.
This code represents diseases of the digestive system complicating pregnancy during the first trimester (less than 14 weeks 0 days).
Example 1: A pregnant woman in her 10th week of gestation presents with severe nausea and vomiting (hyperemesis gravidarum). The physician diagnoses this as a complication of her pregnancy and uses the code O99.611., A pregnant woman at 12 weeks gestation experiences persistent heartburn and acid reflux. The physician determines this is gastroesophageal reflux disease (GERD) exacerbated by her pregnancy, using code O99.611., A 7-week pregnant woman experiences worsening constipation attributed to pregnancy hormones and uses code O99.611.
Documentation should include details about the specific digestive system disorder, its severity, and its relationship to the pregnancy. The trimester of pregnancy should also be clearly documented.
** This code is for use only on maternal records, never on newborn records. An additional code can be used to specify the underlying digestive system condition.
