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

This code describes a multifetal pregnancy where one or more fetuses have demised within the first trimester, but at least one other fetus remains viable and the pregnancy is continuing. It indicates a partial fetal loss in a multiple gestation.

Use this code when documentation confirms a multiple gestation with the intrauterine death of one or more fetuses during the first trimester (up to 13 weeks 6 days gestation), and the pregnancy is ongoing with at least one live fetus. Supporting documentation would include ultrasound reports confirming fetal demise of one or more, and viability of others.

• Always assign an additional code from category O30 to specify the type of multiple gestation (e.g., O30.0- for twin pregnancy).
• Do not use this code if all fetuses have demised; instead, use codes for missed abortion or other fetal death.
• Ensure the trimester is clearly documented as "first trimester" to support the specificity of this code.
