Pregnancy with inconclusive fetal viability, other fetus

This code signifies a multifetal pregnancy where the viability of one or more fetuses cannot be definitively determined. This uncertainty typically arises from inconclusive diagnostic findings, such as ambiguous ultrasound results, regarding fetal heart activity or other indicators of life.

Apply this code when documentation clearly indicates a multifetal pregnancy with an indeterminate status for at least one fetus's viability. This is often used when initial assessments are equivocal and further evaluation is pending or has not yielded a conclusive determination of live or demise.

• This code is for other fetus in a multifetal pregnancy; ensure the documentation specifies which fetus has inconclusive viability.
• Do not use this code if fetal demise is confirmed for one or more fetuses; instead, use codes from category O31.2- or O36.4-.
• Always sequence this code as a secondary diagnosis when a more specific obstetric complication is also present.
