Polyhydramnios, third trimester, not applicable or unsp

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

Use this code when documentation specifies polyhydramnios occurring in the third trimester without further specification of severity (mild, moderate, severe) or when the severity is not applicable. This code is appropriate when the medical record clearly states "polyhydramnios, third trimester" and no other trimester-specific code is more appropriate.

• Always confirm the trimester of pregnancy from the medical record.
• If the severity of polyhydramnios (mild, moderate, severe) is documented, a more specific code should be used.
• Code any associated maternal or fetal conditions contributing to the polyhydramnios as additional diagnoses.
