Pregnancy with inconclusive fetal viability, fetus 3

This code indicates a pregnancy where the viability of the third fetus cannot be definitively determined. This often occurs when diagnostic tests, such as ultrasound, are inconclusive regarding the presence of a fetal heartbeat or other signs of life for one specific fetus in a multiple gestation.

Use this code when documentation explicitly states "inconclusive fetal viability" for fetus 3 in a multifetal pregnancy. This typically arises during early pregnancy assessments or when there are concerns about fetal well-being in a triplet or higher-order gestation. Documentation should clearly specify which fetus (e.g., "fetus 3") has inconclusive viability.

• Ensure the documentation specifies "fetus 3" for the inconclusive viability; otherwise, a different character for the fetus number or an unspecified code may be appropriate.
• This code is for inconclusive viability, not confirmed fetal demise or confirmed viable fetus.
• Always sequence this code as a secondary diagnosis following the primary code for the pregnancy.
