Oth disrd of amniotic fluid and membrns, first tri, fetus 1

This code signifies a diagnosis of an unusual or abnormal condition affecting the amniotic fluid or membranes during the first trimester of pregnancy, specifically for the first fetus in a multiple gestation. This includes conditions not otherwise classified as oligohydramnios, polyhydramnios, or premature rupture of membranes.

Apply this code when documentation indicates a specified, but uncommon, disorder of the amniotic fluid or membranes identified in the first trimester, such as amniotic bands or unusual fluid characteristics, for the first fetus. Documentation should clearly state the specific disorder and the gestational age.

• Ensure the documentation explicitly states "first trimester" and specifies the "first fetus" if applicable.
• Do not use for oligohydramnios, polyhydramnios, or premature rupture of membranes, as these have more specific codes.
• Requires physician documentation of the specific "other specified" disorder, not just a general abnormality.
