Mat care other fetal abnlt and damage, fetal GI anomal, fts3

This code signifies maternal care provided due to a suspected or confirmed gastrointestinal anomaly in the third fetus of a multiple gestation pregnancy. This includes conditions such as esophageal atresia, duodenal atresia, gastroschisis, or omphalocele affecting the third fetus. The mother is receiving medical attention specifically because of this identified fetal issue.

Use this code when documentation indicates maternal care for a third fetus diagnosed with or suspected of having a gastrointestinal anomaly. This applies to situations where the mother is undergoing monitoring, counseling, or interventions directly related to the fetal GI condition. Supporting documentation would include ultrasound reports, fetal anomaly scans, or physician notes detailing the specific GI anomaly in the third fetus.

• Ensure the documentation clearly specifies "fetus 3" in a multiple gestation pregnancy.
• Do not use this code if the anomaly is not gastrointestinal; refer to other O35.D subcategories for different fetal abnormalities.
• Sequence this code as a secondary diagnosis following the primary reason for the encounter, if applicable, or as the primary diagnosis if the maternal care is solely for the fetal anomaly.
