About coding multiple gestation

The ICD-10-CM code for multiple gestation is O30.9 (Multiple gestation, unspecified).

Within O30, choose O30.9 (unspecified) only when documentation doesn't support a more specific option: twin pregnancy (O30.0), triplet pregnancy (O30.1), Quadruplet pregnancy (O30.2) and other specified multiple gestation (O30.8).

To report this condition, pick the subcode that matches the documentation: O30.90 (unspecified trimester), O30.91 (first trimester), O30.92 (second trimester) and O30.93 (third trimester).

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