Cont preg aft spon abort of one fetus or more, 2nd tri, fts3

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 develop. It specifically identifies the third fetus in a multiple gestation where the spontaneous abortion of another fetus has occurred.

Use this code when documentation indicates a multifetal pregnancy (e.g., triplets or more) where a partial spontaneous abortion has occurred in the second trimester, and the third fetus is still viable. This code requires clear documentation of the specific fetus affected and the gestational age at the time of the spontaneous abortion.

• Ensure the documentation clearly identifies the specific fetus (e.g., "fetus 3") that is continuing after the loss of another.
• Verify the gestational age aligns with the second trimester (14 weeks 0 days to 27 weeks 6 days).
• Always sequence this code after the primary obstetric code indicating the current pregnancy status.
