Pregnancy with inconclusive fetal viability, fetus 4

This code signifies a pregnancy where the viability of the fourth fetus cannot be definitively determined. This often occurs when there are conflicting or insufficient findings from diagnostic tests, such as ultrasound, to confirm or rule out fetal life. The status of the fetus remains uncertain, requiring further evaluation.

Use this code when documentation indicates an ongoing pregnancy with a multifetal gestation (specifically the fourth fetus) and the viability of that particular fetus is unclear. This applies when imaging or other diagnostic studies yield equivocal results regarding the presence of a heartbeat or other signs of life for the fourth fetus.

• Ensure the documentation clearly specifies "fetus 4" when using this code, as laterality and fetal number are crucial for accurate reporting.
• This code should be used when viability is truly "inconclusive," not simply "not yet determined" in early gestation where viability is expected to be confirmed later.
• Always sequence this code as a secondary diagnosis if a more definitive maternal condition or complication is present.
