Cont preg aft spon abort of one fts or more, first tri, fts5

This code describes a multifetal pregnancy where one or more fetuses have been spontaneously aborted during the first trimester, but at least one other fetus continues to develop. Specifically, it identifies the fifth fetus in a multiple gestation as the one that was spontaneously aborted.

Apply this code when documentation clearly indicates a multifetal pregnancy with a partial spontaneous abortion of one or more fetuses in the first trimester, and the specific fetus (e.g., fetus 5) that was lost is identified. This is typically supported by ultrasound reports detailing the demise of one or more gestational sacs/fetuses while others remain viable.

• Ensure the documentation specifies "first trimester" for the spontaneous abortion.
• Confirm the specific fetus number (e.g., fetus 5) is clearly identified as the one aborted.
• Sequence this code after the primary code for the ongoing multifetal pregnancy (e.g., O30.x).
