Cont preg aft uterin dth of one fetus or more, 2nd tri, fts4

This code signifies a multifetal pregnancy where one or more fetuses have demised during the second trimester, but at least one other fetus remains viable and the pregnancy is continuing. It specifically identifies the fourth fetus as the one that has died. This condition presents significant risks to the surviving fetus(es) and the pregnant patient.

Use this code when documentation clearly indicates a multifetal pregnancy (e.g., twins, triplets, quadruplets) with intrauterine fetal demise (IUFD) of one or more fetuses occurring between 14 weeks 0 days and 27 weeks 6 days gestation, and the pregnancy is ongoing with at least one viable fetus. The medical record must specify that it was the fourth fetus that demised.

• Ensure the documentation explicitly states the trimester of demise and the specific fetus (e.g., "demise of fetus D" or "fourth fetus").
• This code is for the continuing pregnancy; do not use if all fetuses have demised.
• Sequence this code as a secondary diagnosis, following the code for the primary reason for the encounter (e.g., routine prenatal care, complications related to the demise).
