Answer: No. You should report 632 (Missed abortion) only when the fetus has no heart beat prior to the onset of abortion, and she has not expelled the fetus. If the patient has had a missed abortion, then the next week spontaneously aborts the fetus, her diagnosis at that encounter will be 634.91 (Spontaneous abortion incomplete without complication). In the case you presented, the ob-gyn did not perform the dilation and curettage (D&C) for a missed abortion but for an incomplete spontaneous abortion.
