Oligohydramnios, second trimester, not applicable or unsp

This code signifies a reduced volume of amniotic fluid surrounding the fetus during the second trimester of pregnancy. Oligohydramnios can indicate potential fetal compromise, renal anomalies, or placental insufficiency.

Assign this code when documentation confirms oligohydramnios detected between 14 weeks 0 days and 27 weeks 6 days gestation, and the specific type or cause is not further specified or applicable. This diagnosis is typically made via ultrasound measurement of the amniotic fluid index (AFI) or deepest vertical pocket (DVP).

• Ensure the documentation clearly specifies "second trimester" for accurate code assignment.
• If the cause of oligohydramnios is known (e.g., premature rupture of membranes), a more specific code should be used.
• The "X0" placeholder indicates that a specific type or cause is not applicable or unspecified for this trimester.
