Cont preg aft spon abort of one fts or more, third tri, fts2

This code signifies a multifetal pregnancy where at least one fetus has been spontaneously aborted, but the pregnancy continues with one or more viable fetuses into the third trimester. It specifically identifies the second fetus in such a scenario.

Apply this code when documentation confirms a prior spontaneous abortion of one or more fetuses in a multifetal pregnancy, and the remaining pregnancy has progressed beyond 28 weeks' gestation. Documentation should clearly indicate the viability of at least one remaining fetus and specify the fetal number.

• Ensure the documentation explicitly states "third trimester" and identifies the specific fetus (e.g., "fetus 2").
• Do not confuse this with codes for threatened abortion or other complications of multifetal pregnancy without a confirmed prior spontaneous abortion.
• Always sequence this code after the primary code for the ongoing multifetal pregnancy, if applicable.
