Cont preg aft spon abort of one fetus or more, 2nd tri, fts2

This code describes a multifetal pregnancy where one or more fetuses have been spontaneously aborted during the second trimester, but at least one fetus remains viable and the pregnancy is continuing. It specifically identifies the second fetus in a multiple gestation.

Use this code when documentation confirms a spontaneous abortion of one or more fetuses in a multifetal pregnancy during the second trimester (weeks 14-27+6 days), with at least one fetus still viable. This code is assigned to the second fetus in such a scenario. Documentation should clearly state the trimester, the spontaneous loss of one or more fetuses, and the continued viability of the remaining fetus(es).

• Always assign a code from category O31 for each continuing fetus in a multifetal pregnancy following a spontaneous abortion of one or more.
• Ensure the documentation specifies the trimester of the spontaneous abortion and the specific fetus (e.g., fetus 1, fetus 2) to which the code applies.
• Do not confuse with codes for blighted ovum or missed abortion of all fetuses, as this code implies a continuing pregnancy.
