Oth disrd of amniotic fluid and membrns, third tri, fetus 3

This code signifies a maternal diagnosis of an abnormal condition of the amniotic fluid or membranes, not elsewhere classified, occurring during the third trimester of pregnancy. It specifically indicates that the third fetus in a multiple gestation is affected by this disorder. Examples include conditions like amniotic band syndrome or chorioamnionitis not specified as bacterial, affecting the third fetus.

Use this code when documentation clearly identifies a specified, but not more precisely classified, disorder of the amniotic fluid or membranes in a pregnant patient in her third trimester. This code is appropriate when the disorder is specifically attributed to the third fetus in a multifetal pregnancy. Documentation should specify the trimester and the affected fetus.

• Ensure the medical record explicitly states the third trimester and identifies the third fetus as the one affected by the amniotic fluid/membrane disorder.
• Do not use this code if a more specific code for the amniotic fluid or membrane disorder is available (e.g., polyhydramnios, oligohydramnios).
• Always sequence this code after the primary obstetric code indicating the reason for the encounter, if applicable.
