Cont preg aft spon abort of one fts or more, third tri, fts4

This code signifies an ongoing pregnancy in the third trimester following the spontaneous loss of one or more fetuses in a multifetal gestation. It specifically identifies the fourth fetus as the one continuing to develop. This scenario involves a partial fetal demise where at least one fetus is still viable.

Assign this code when documentation confirms a multifetal pregnancy where one or more fetuses have been spontaneously aborted, and at least one fetus (specifically identified as the fourth) is still viable and the pregnancy has progressed into the third trimester. This would be supported by ultrasound reports detailing fetal demise of one or more fetuses and the continued viability of the fourth, along with gestational age documentation.

• Ensure documentation clearly specifies "fetus 4" as the continuing fetus in a multifetal pregnancy with partial fetal demise.
• Do not confuse this with complete spontaneous abortion or elective termination; this code is for a continuing pregnancy.
• Sequence this code as a secondary diagnosis, following the code for the current pregnancy complication (e.g., O30.x for multifetal gestation).
