Cont preg aft uterin dth of one fts or more, third tri, fts3

This code signifies a multifetal pregnancy where at least one fetus has demised in utero during the third trimester, but the pregnancy is continuing with one or more viable fetuses. Specifically, it identifies the third fetus in a multiple gestation as the one that has died. This condition carries significant risks for the remaining viable fetuses and the mother.

Use this code when documentation clearly indicates the intrauterine demise of one or more fetuses in a multifetal pregnancy, specifically identifying the third fetus as the demised one, and the pregnancy is still ongoing in the third trimester. Supporting documentation includes ultrasound reports confirming fetal demise and viability of other fetuses, as well as physician notes detailing the gestational age and ongoing pregnancy management.

• Ensure the documentation specifies "third trimester" and clearly identifies which fetus (e.g., fetus 3) has demised.
• Always sequence this code as a secondary diagnosis, following the primary code for the multifetal pregnancy (e.g., O30.0-).
• Do not confuse with codes for complete miscarriage or stillbirth of all fetuses; this code is only for continuing pregnancies.
