Polyhydramnios, unspecified trimester, fetus 5

This code signifies an excessive accumulation of amniotic fluid surrounding the fetus, where the specific gestational trimester of diagnosis is not documented. It indicates a diagnosis of polyhydramnios affecting the fifth fetus in a multiple gestation pregnancy.

Apply this code when the medical record clearly states polyhydramnios in a multiple gestation pregnancy involving five fetuses, but the trimester of diagnosis is not specified. Documentation should include a diagnosis of polyhydramnios and explicitly identify it as affecting the fifth fetus.

• Ensure documentation specifies "fetus 5" in a multiple gestation. If the fetus number is not specified, a different code for unspecified fetus would be appropriate.
• Avoid using this code if the trimester of diagnosis (e.g., first, second, third) is clearly documented; instead, select the trimester-specific polyhydramnios code.
• Always sequence this code after the primary obstetric complication or condition that led to the polyhydramnios, if applicable.
