O30.23Quadruplet pregnancy, quadrachorionic/quadra-amniotic

O30.23 is the ICD-10-CM diagnosis code for Quadruplet pregnancy, quadrachorionic/quadra-amniotic. It belongs to category O30 (multiple gestation), block O30-O48 (maternal care related to the fetus and amniotic cavity and possible delivery problems) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within O30.2 (Quadruplet pregnancy), O30.23 is specifically for Quadruplet pregnancy, quadrachorionic/quadra-amniotic. Related codes cover unspecified number of placenta and unspecified number of amniotic sacs (O30.20), with two or more monochorionic fetuses (O30.21), with two or more monoamniotic fetuses (O30.22) and unable to determine number of placenta and number of amniotic sacs (O30.29).

To report this condition, pick the subcode that matches the documentation: O30.231 (first trimester), O30.232 (second trimester), O30.233 (third trimester) and O30.239 (unspecified trimester).

It was added in FY2019, effective October 1, 2018.
