Quad preg, unsp num plcnta & amnio sacs, third trimester

This code signifies a pregnancy involving four fetuses, currently in the third trimester. It is used when the specific number of placentas (e.g., monochorionic, dichorionic) and amniotic sacs (e.g., monoamniotic, diamniotic) has not been determined or documented.

Apply this code for a patient confirmed to be carrying quadruplets who is beyond 28 weeks gestation, and the chorionicity and amnionicity are not specified in the medical record. This is appropriate when initial ultrasound reports or subsequent documentation do not provide details on the placental or amniotic sac configuration.

• Always strive for greater specificity regarding chorionicity and amnionicity if documented, as more specific codes exist.
• Ensure the documentation clearly states "quadruplet pregnancy" and the gestational age indicates the third trimester.
• This code should be sequenced as a primary diagnosis for the maternal condition during pregnancy.
