Cont preg aft spon abort of one fts or more, third tri, fts3

This code indicates a multifetal pregnancy where one or more fetuses have been spontaneously aborted, but at least one fetus remains viable and the pregnancy is continuing into the third trimester. Specifically, it identifies the third fetus in such a scenario. This condition signifies a partial loss within a multiple gestation, with ongoing viability of other fetuses.

Apply this code when documentation clearly states a multifetal pregnancy, a spontaneous abortion of one or more fetuses has occurred, and the pregnancy is now in the third trimester with at least one fetus still viable. This code is used to specify the third fetus in the continuing pregnancy. Supporting documentation includes ultrasound reports confirming viability of remaining fetuses and gestational age, along with physician notes detailing the spontaneous abortion event.

• Ensure the documentation specifies "third trimester" and clearly identifies the third fetus as the one being coded for the continuing pregnancy.
• Do not confuse this with codes for complete spontaneous abortion (O03.-) or other complications of multiple gestation where all fetuses are lost.
• Always sequence this code after the primary code for the ongoing multifetal pregnancy (e.g., O30.-) and any codes for the complications of the spontaneous abortion.
