Cont preg aft spon abort of one fetus or more, 2nd tri, unsp

This code describes a multifetal pregnancy where one or more fetuses have been spontaneously aborted during the second trimester, but at least one fetus continues to be viable. It indicates a partial loss within a multiple gestation, specifically occurring between 14 weeks 0 days and 27 weeks 6 days of gestation.

Use this code when documentation clearly states a spontaneous fetal demise of one or more fetuses in a multiple gestation, with the remaining fetus(es) still viable, and the event occurred in the second trimester. This code is appropriate for ongoing care related to the continuing pregnancy after such an event.

• Ensure the documentation specifies "spontaneous" abortion and the "second trimester" for the demised fetus(es).
• Always sequence this code as a secondary diagnosis, following the code for the current pregnancy (e.g., O30.x for multiple gestation).
• Do not use this code if all fetuses were spontaneously aborted or if the abortion occurred in the first or third trimester.
