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

This code signifies a multifetal gestation involving four fetuses (quadruplets) that has progressed into the third trimester. The specific arrangement of placentas and amniotic sacs for these quadruplets could not be determined through diagnostic imaging or clinical assessment. This situation often presents increased risks for both the mother and the fetuses.

Apply this code when documentation clearly indicates a quadruplet pregnancy in the third trimester, and there is an explicit statement that the chorionicity and amnionicity (number of placentas and amniotic sacs) are unknown or could not be determined. This typically occurs when imaging is inconclusive or incomplete regarding these specific details.

• Ensure the documentation specifies "quadruplet" pregnancy and "third trimester."
• Only use this code when the chorionicity and amnionicity are explicitly stated as "unknown" or "undetermined." Do not default to this code if these details are simply not mentioned.
• Always sequence this code as the principal diagnosis when it is the reason for the encounter, followed by any associated maternal or fetal complications.
