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

This code describes a multifetal pregnancy where one or more fetuses have been spontaneously aborted, but at least one fetus continues to develop. Specifically, it identifies the fourth fetus in such a pregnancy. This scenario indicates a partial loss within a multiple gestation.

Use this code when documentation clearly indicates a multiple gestation pregnancy where one or more fetuses have been spontaneously aborted, and the remaining pregnancy is ongoing. This code is applied to the fourth fetus when its status as continuing is being documented. Supporting documentation would include ultrasound reports confirming the presence of a viable fetus(es) after a spontaneous abortion of another fetus(es) from the same gestation.

• Always sequence this code after the primary code for the continuing pregnancy (e.g., O30.1- for twin pregnancy).
• Ensure the documentation specifies which fetus (e.g., fetus 4) is being described as continuing.
• Do not use this code if all fetuses have been spontaneously aborted; instead, use codes from category O03.
