Official Coding Guidelines
Retained products post abortion—code O03.4 or O07.4 unless complicationSubsequent encounters for retained products of conception following a spontaneous abortion or elective termination of pregnancy, without complications are assigned O03.4, Incomplete spontaneous abortion without complication, or code O07.4, Failed attempted termination of pregnancy without complication. This advice is appropriate even when the patient was discharged previously with a discharge diagnosis of complete abortion. If the patient has a specific complication associated with the spontaneous abortion or elective termination of pregnancy in addition to retained products of conception, assign the appropriate complication code (e.g., O03.-, O04.-, O07.-) instead of code O03.4 or O07.4.
