Polyhydramnios, second trimester, not applicable or unsp

This code indicates an excessive accumulation of amniotic fluid surrounding the fetus during the second trimester of pregnancy. Polyhydramnios can be idiopathic or associated with maternal conditions like diabetes, or fetal anomalies such as gastrointestinal obstructions or central nervous system defects.

Use this code when documentation specifies polyhydramnios diagnosed between 14 weeks 0 days and 27 weeks 6 days gestation, without further specification of the type or severity. This code is appropriate when the medical record confirms the diagnosis and the gestational age falls within the second trimester.

• Ensure the medical record clearly states "second trimester" or provides a gestational age falling within 14-27 weeks.
• Do not use this code if the polyhydramnios is specified as mild, moderate, or severe; instead, use the appropriate subcategory.
• Always code any associated maternal or fetal conditions contributing to the polyhydramnios, such as gestational diabetes or fetal anomalies.
