About O30.2
O30.2 is the ICD-10-CM diagnosis code for Quadruplet pregnancy. 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 5 subcodes must be used instead.
Within O30 (multiple gestation), O30.2 is specifically for Quadruplet pregnancy. Related codes cover twin pregnancy (O30.0), triplet pregnancy (O30.1), other specified multiple gestation (O30.8) and unspecified (O30.9).
To report this condition, pick the subcode that matches the documentation: O30.20 (unspecified number of placenta and unspecified number of amniotic sacs), O30.21 (with two or more monochorionic fetuses), O30.22 (with two or more monoamniotic fetuses), O30.23 (quadrachorionic/quadra-amniotic) and O30.29 (unable to determine number of placenta and number of amniotic sacs).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
