Cont preg aft spon abort of one fts or more, third tri, fts5

This code describes a multifetal pregnancy where one or more fetuses have been spontaneously aborted, but at least one fetus continues to develop into the third trimester. It specifically indicates that the fifth fetus in the original multiple gestation is the one continuing.

Use this code when documentation clearly indicates a history of spontaneous abortion of one or more fetuses in a multifetal pregnancy, with the remaining fetus(es) having progressed to the third trimester. This applies when the patient is currently pregnant and the fifth fetus is the one still viable.

• Ensure documentation specifies the number of fetuses originally and which specific fetus (e.g., fifth) is continuing.
• This code requires an additional code from category Z3A to specify the weeks of gestation.
• Do not confuse with codes for missed abortion (O02.1) or blighted ovum (O02.0) if a continuing pregnancy is present.
