Cont preg aft spon abort of one fts or more, first tri, fts4

This code describes a multifetal pregnancy where one or more fetuses have been spontaneously aborted, but at least one fetus continues to develop. This specific code applies when the spontaneous abortion occurred during the first trimester and refers to the fourth fetus in the original multifetal gestation.

Use this code for ongoing multifetal pregnancies following the loss of one or more fetuses in the first trimester. Documentation should clearly indicate a prior spontaneous abortion of one or more fetuses, the gestational age at the time of the loss (first trimester), and the specific fetus number (fetus 4) that was lost.

• Ensure documentation specifies the trimester of the spontaneous abortion and the number of the fetus that was lost.
• This code is for the remaining pregnancy, not the spontaneous abortion itself.
• Sequence this code as a secondary diagnosis following the code for the ongoing multifetal pregnancy (e.g., O30.-).
