Pregnancy with inconclusive fetal viability, fetus 1

This code signifies a pregnancy where the viability of the first fetus cannot be definitively determined. This often occurs early in gestation when ultrasound findings are ambiguous, such as an empty gestational sac or a fetal pole without cardiac activity, and further evaluation is needed.

Use this code when ultrasound or other diagnostic tests indicate an uncertain status regarding the life or death of a single fetus (fetus 1) within the uterus. Documentation should clearly state "inconclusive fetal viability," "questionable viability," or similar terminology, specifically for the first identified fetus.

• Ensure documentation specifies "fetus 1" if multiple gestations are present, otherwise, use the unspecified fetus code.
• This code is temporary; expect a definitive diagnosis (e.g., live birth, fetal demise) to replace it upon subsequent evaluation.
• Do not use this code if fetal demise is confirmed; instead, code for fetal death.
