Quad preg, unable to dtrm num plcnta & amnio sacs, unsp tri

This code signifies a pregnancy involving four fetuses where the number of placentas (chorionicity) and amniotic sacs (amnionicity) cannot be determined through diagnostic imaging or clinical assessment. It indicates a lack of specific information regarding the membrane configuration in a quadruplet gestation.

Use this code when documentation clearly states a quadruplet pregnancy but lacks details on chorionicity and amnionicity, and the trimester is not specified. This is often applicable when initial ultrasound findings are inconclusive or incomplete regarding the membrane structure.

• Ensure documentation explicitly states "quadruplet pregnancy" and the inability to determine chorionicity/amnionicity.
• Avoid using this code if the number of placentas or sacs is known, even if only partially.
• Do not use this code if the trimester is documented; instead, select the trimester-specific code.
