Cont preg aft uterin dth of one fetus or more, 2nd tri, fts1

This code signifies a multifetal pregnancy where at least one fetus has demised in the second trimester, but the remaining fetus(es) continue to develop. It specifically identifies the first fetus as the one that has demised. This condition presents unique management challenges due to potential risks to the surviving fetus(es) and the pregnant individual.

Apply this code when documentation confirms a multifetal gestation with the intrauterine demise of one or more fetuses during the second trimester (weeks 14 through 27+6 days), and the pregnancy is ongoing. This code is specifically for the first fetus when multiple fetuses are present. Documentation should clearly state the gestational age at the time of demise and the viability of the remaining fetus(es).

• Ensure the documentation specifies "second trimester" for the demise; otherwise, a different trimester code is required.
• Confirm the specific fetus (e.g., Fetus 1, Fetus 2) to which the demise applies, as separate codes exist for other fetuses.
• Always sequence this code as a secondary diagnosis, following the code for the multifetal pregnancy (e.g., O30.-).
