Oth disrd of amniotic fluid and membrns, first tri, fetus 5

This code signifies a diagnosed abnormality of the amniotic fluid or membranes, other than those specifically classified elsewhere, occurring during the first trimester of pregnancy. This includes conditions like oligohydramnios or polyhydramnios of unknown etiology, or other structural issues with the amniotic sac, affecting the fifth fetus in a multiple gestation.

Use this code when documentation clearly indicates a specified, but not otherwise classified, disorder of the amniotic fluid or membranes identified in the first trimester. This applies to the fifth fetus in a multifetal pregnancy. Supporting documentation should detail the specific disorder and the gestational age at diagnosis.

• Ensure the documentation specifies "first trimester" and identifies the fifth fetus.
• Do not use for conditions with more specific ICD-10-CM codes (e.g., premature rupture of membranes).
• This code requires an additional code to identify the type of multiple gestation (e.g., O30.1-).
