Disord of amnio fluid and membrns, unsp, second tri, fetus 1

This code signifies an uncharacterized abnormality of the amniotic fluid or fetal membranes occurring during the second trimester of pregnancy, specifically affecting the first fetus in a multiple gestation. It indicates that the exact nature of the fluid or membrane disorder is not specified in the medical record.

This code is appropriate when documentation indicates an unspecified issue with the amniotic fluid (e.g., polyhydramnios, oligohydramnios) or membranes (e.g., premature rupture of membranes, chorioamnionitis) during the second trimester, and the specific type of disorder is not documented. It should be used for the first fetus in a multifetal pregnancy.

• Ensure the documentation explicitly states "unspecified" or lacks further detail regarding the amniotic fluid or membrane disorder.
• Verify the gestational age falls within the second trimester (14 weeks 0 days to 27 weeks 6 days).
• Confirm this code is applied to "fetus 1" in cases of multiple gestations; use appropriate codes for other fetuses.
