O30.80Other specified multiple gestation, unspecified number of placenta and unspecified number of amniotic sacs

O30.80 is the ICD-10-CM diagnosis code for other specified multiple gestation, unspecified number of placenta and unspecified number of amniotic sacs. 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 O30.8, choose O30.80 (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 (O30.81), with two or more monoamniotic fetuses (O30.82), number of chorions and amnions are both equal to the number of fetuses (O30.83) and unable to determine number of placenta and number of amniotic sacs (O30.89).

To report this condition, pick the subcode that matches the documentation: O30.801 (first trimester), O30.802 (second trimester), O30.803 (third trimester) and O30.809 (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.
