Polyhydramnios, unspecified trimester, fetus 4

This code signifies an excessive accumulation of amniotic fluid surrounding the fetus, where the specific gestational trimester is not documented. It indicates a diagnosis of polyhydramnios without further specification of the pregnancy stage.

Use this code when the medical record clearly states polyhydramnios but does not specify the trimester of pregnancy, and the documentation identifies the condition as affecting fetus 4 in a multiple gestation. This code is appropriate when the physician's notes or ultrasound reports confirm the diagnosis without trimester detail.

• Ensure documentation specifies "fetus 4" in a multiple gestation; otherwise, a different code for polyhydramnios in a single gestation or unspecified fetus would be more appropriate.
• Always attempt to clarify the trimester with the provider if possible, as more specific codes exist for polyhydramnios by trimester.
• This code should be sequenced as a secondary diagnosis when a more definitive obstetric complication or fetal condition is identified.
