Cont preg aft spon abort of one fts or more, first tri, fts1

This code describes a multifetal pregnancy where one or more fetuses have been spontaneously aborted during the first trimester, but at least one viable fetus remains. It indicates a partial loss within a multiple gestation, specifically for the first identified fetus.

Use this code when documentation clearly states a spontaneous abortion of one or more fetuses in a multifetal pregnancy during the first trimester, with at least one remaining viable fetus. This applies when the remaining pregnancy is ongoing. Documentation should specify the trimester and the number of fetuses involved.

• Ensure the documentation specifies "first trimester" for the spontaneous abortion.
• Confirm that the pregnancy is continuing with at least one viable fetus; otherwise, a complete abortion code may be more appropriate.
• This code requires an additional character for the fetus number (e.g., X1 for fetus 1, X2 for fetus 2, etc.) to specify which fetus is being described.
