Cont preg aft spon abort of one fts or more, third tri, oth

This code signifies a multifetal pregnancy where one or more fetuses have been spontaneously aborted, but at least one fetus continues to be viable and the pregnancy has progressed into the third trimester. It indicates a partial loss within a multiple gestation, specifically occurring after 28 weeks of gestation.

Apply this code when documentation clearly states a spontaneous abortion of one or more fetuses in a multifetal pregnancy, with the remaining fetus(es) continuing to term, and the event occurred during the third trimester. This is typically used in conjunction with codes for the outcome of the continuing pregnancy.

• Ensure documentation specifies "spontaneous abortion" and not an induced termination or fetal demise without expulsion.
• Verify the gestational age at the time of the spontaneous abortion to confirm it falls within the third trimester (28 weeks or more).
• This code should be sequenced as a secondary diagnosis, following the code for the current obstetric condition or outcome of the continuing pregnancy.
