About coding triplet pregnancy

The ICD-10-CM code for triplet pregnancy is O30.10 (Triplet pregnancy, unspecified number of placenta and unspecified number of amniotic sacs). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O30.10.

Within O30.1, choose O30.10 (unspecified number of placenta and unspecified number of amniotic sacs) only when documentation doesn't support a more specific option: with two or more monochorionic fetuses (O30.11), with two or more monoamniotic fetuses (O30.12), trichorionic/triamniotic (O30.13) and unable to determine number of placenta and number of amniotic sacs (O30.19).

To report this condition, pick the subcode that matches the documentation: O30.101 (first trimester), O30.102 (second trimester), O30.103 (third trimester) and O30.109 (unspecified trimester).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
