Cont preg aft uterin dth of one fetus or more, unsp tri, oth

This code signifies a multifetal pregnancy where at least one fetus has demised in utero, but the remaining fetus(es) continue to develop. The specific gestational age of the pregnancy at the time of fetal demise is not documented or is unknown.

Apply this code when documentation confirms a multifetal gestation with the intrauterine death of one or more fetuses, and the pregnancy is ongoing with at least one viable fetus. This code is appropriate when the trimester of the demise is not specified in the medical record.

• Always sequence this code as a secondary diagnosis, following the code for the specific type of multifetal pregnancy (e.g., twin, triplet).
• Ensure documentation clearly states "unspecified trimester" or lacks information regarding the trimester of demise.
• Distinguish from codes indicating a complete intrauterine death of all fetuses, or when the trimester of demise is known.
