2025 ICD-10-CM code O31.30X3

Continuing pregnancy after elective fetal reduction of one fetus or more, unspecified trimester, fetus 3.

This code is for use in maternal records only. It is not for use on newborn records.

Medical necessity for the fetal reduction procedure must be documented if applicable. In the case of elective reduction, the reasons for the patient's choice should be documented, if possible.

The physician managing the patient's pregnancy is responsible for documenting and coding this condition.

In simple words: This code indicates that a woman is still pregnant with her third baby after a procedure to reduce the number of fetuses she was carrying. The part of the pregnancy (1st, 2nd, or 3rd trimester) is not specified.

This code is used to describe a continuing pregnancy after an elective fetal reduction procedure has been performed, where one or more fetuses have been removed.The specific trimester of the pregnancy is unspecified, and this code is specific to fetus 3.

Example 1: A patient undergoes an elective multifetal pregnancy reduction at 15 weeks. She began the pregnancy with quadruplets; one fetus is selectively terminated. The remaining three fetuses continue to develop.Each fetus would be coded separately with O31.30X# (# representing fetus number)., A woman pregnant with triplets undergoes a fetal reduction procedure in her second trimester. One fetus is terminated, and the remaining two continue to thrive. This would be coded with O31.30X# for each remaining fetus., A patient is pregnant with twins and undergoes elective fetal reduction early in her first trimester to reduce the pregnancy to a singleton. The code O31.30X1 would be used to indicate the continued singleton pregnancy of fetus 1.

Documentation should clearly indicate the original number of fetuses, the number of fetuses reduced, the number of remaining fetuses, and that the fetal reduction was elective. The trimester should also be documented, though this code is used when the trimester is unspecified. Each continuing pregnancy after fetal reduction should be coded separately. Each remaining fetus is reported individually using the appropriate seventh character.
