Cont preg aft uterin dth of one fts or more, unsp tri, fts1

This code signifies a multifetal pregnancy where at least one fetus has demised in utero, but the remaining fetus(es) continue to develop. It indicates a complex obstetric situation requiring close monitoring due to the risks associated with the retained dead fetus.

Apply this code when documentation clearly states a diagnosis of intrauterine fetal demise (IUFD) of one or more fetuses in a multifetal gestation, with the ongoing viability of at least one other fetus, and the trimester is not specified. Supporting documentation would include ultrasound reports confirming fetal demise and continued viability of other fetuses, along with physician notes detailing the diagnosis.

• Ensure documentation specifies "fetus 1" if applicable, as laterality/fetus number is crucial for accurate coding.
• Do not use this code if all fetuses have demised; instead, refer to codes for single or multiple intrauterine fetal death without continuing pregnancy.
• Always sequence this code as a secondary diagnosis, following the primary code for the current obstetric condition or reason for encounter.
