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

This code signifies a multifetal pregnancy where at least one fetus has demised in utero, but the pregnancy continues 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 a multifetal pregnancy with the intrauterine demise of the third fetus, and the pregnancy is ongoing. This diagnosis is typically made via ultrasound confirmation of absent fetal heart activity in one fetus while others remain viable. Documentation should specify the number of fetuses and which one has demised.

• Ensure the documentation explicitly identifies the third fetus as the one that has demised; otherwise, an unspecified fetus code (O31.20X0) or a different fetus number should be used.
• This code is for ongoing pregnancies; if the entire pregnancy has terminated, a different code set would apply.
• Always sequence this code after the primary obstetric complication or condition, if applicable, and in conjunction with codes for the type of multifetal gestation (e.g., O30.1- for twin pregnancy).
