Oth mult gest, num chorions & amnions = num ftses, unsp tri

This code signifies a multiple gestation pregnancy where the number of placentas (chorions) and amniotic sacs (amnions) is equal to the number of fetuses, but the specific type of multiple gestation is not otherwise specified. This indicates that each fetus has its own placenta and amniotic sac, a condition known as dichorionic-diamniotic (DCDA) for twins, trichorionic-triamniotic for triplets, etc.

Use this code when documentation confirms a multiple gestation with each fetus having its own chorion and amnion, but the specific type of multiple gestation (e.g., twin, triplet) is not explicitly stated in the record. This is common when the exact number of fetuses is known, but the specific "type" of multiple gestation (e.g., twin, triplet) is not separately coded or specified beyond the chorionicity/amnionicity.

• Ensure documentation clearly states that the number of chorions and amnions matches the number of fetuses.
• Avoid using this code if the specific type of multiple gestation (e.g., twin, triplet) is documented and a more specific code is available.
• This code should be sequenced as a secondary diagnosis following the primary code for the specific type of multiple gestation (e.g., O30.0- for twin pregnancy).
