In simple words: This code is used when a woman is still pregnant after having one or more babies removed during pregnancy (elective fetal reduction). This applies to the second remaining baby and the trimester isn't specified.

This code classifies a continuing pregnancy where one or more fetuses have been electively reduced.The trimester is unspecified, and this particular code refers specifically to the second fetus remaining after the reduction.

Example 1: A patient undergoes elective fetal reduction from a twin pregnancy to a singleton pregnancy at 10 weeks gestation.Code O31.30X2 would be used to describe the continuing singleton pregnancy. The other fetus was electively removed., A patient presents for routine prenatal care after an elective fetal reduction from a triplet pregnancy to a twin pregnancy.Code O31.30X2 would be applied to record the continuing twin pregnancy, provided the specific gestational age and the status of the individual fetuses are addressed with additional codes., During a routine ultrasound at 24 weeks gestation, following a previous elective reduction from quadruplets to twins, the physician documents a continuing pregnancy.O31.30X2 is used for this scenario, alongside further codes that note the gestational age and the health status of the individual fetuses.

Detailed medical records are necessary, including the reason for elective fetal reduction, the gestational age at the time of the reduction, the number of fetuses reduced, and the number of remaining fetuses.Ultrasound reports, operative reports (if applicable), and physician progress notes should support the diagnosis.

** This code is specifically for the continuing pregnancy after fetal reduction.It is crucial to document the gestational age at the time of the procedure and the subsequent gestational age.Additional codes may be needed to fully capture the clinical picture.
