Cont preg aft spon abort of one fts or more, third tri, fts1

This code signifies a multifetal pregnancy where one or more fetuses have been spontaneously aborted, but at least one fetus continues to be viable and the pregnancy has progressed into the third trimester. It specifically identifies the status of the first fetus in such a scenario. This condition represents a complex obstetric situation requiring careful monitoring of the remaining viable fetus(es).

Use this code when documentation clearly indicates a multifetal pregnancy with a confirmed spontaneous abortion of one or more fetuses, and the remaining pregnancy is ongoing in the third trimester. This code is applicable when the patient is admitted or seen for management of the continuing pregnancy after the loss of a co-twin or co-triplet. Documentation should specify the trimester and the number of fetuses involved.

• Ensure documentation specifies "third trimester" and identifies the specific fetus (e.g., "fetus 1").
• Do not confuse with codes for blighted ovum or missed abortion of a singleton pregnancy.
• Sequence this code as a secondary diagnosis following the primary reason for the encounter, if applicable, or as the primary diagnosis if the encounter is solely for monitoring this specific condition.
