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

This code signifies a pregnancy involving four fetuses where, despite diagnostic efforts in the first trimester, the number of placentas and amniotic sacs cannot be definitively determined. This situation presents unique management challenges due to the inherent risks associated with higher-order multiple gestations.

Apply this code when documentation clearly indicates a quadruplet pregnancy in the first trimester, and imaging (e.g., ultrasound) is inconclusive regarding chorionicity and amnionicity. This is typically used when the provider is unable to specify O30.211, O30.221, or O30.231 due to insufficient information.

• Ensure the documentation explicitly states "quadruplet pregnancy" and "first trimester."
• Only use this code if the chorionicity and amnionicity are truly "unable to determine"; otherwise, use a more specific code.
• This code requires a seventh character for the trimester; '1' indicates the first trimester.
