Evaluation of Fetal Death

Definition of Fetal Death

The loss of a fetus at any stage is a fetal demise. According to the 2003 revision of the Procedures for Coding Cause of Fetal Death Under ICD-10, the National Center for Health Statistics defines fetal death as “death prior to the complete expulsion or extraction from its mother of a product of human conception, irrespective of the duration of pregnancy and which is not an induced termination of pregnancy. The death is indicated by the fact that after such expulsion or extraction, the fetus does not breathe or show any other evidence of life, such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles. Heartbeats are to be distinguished from transient cardiac contractions; respirations are to be distinguished from fleeting respiratory efforts or gasps.”

In the United States, the term stillbirth or fetal demise does not have a standard definition.

For statistical purposes, fetal losses are classified according to gestational age. A death that occurs prior to 20 weeks’ gestation is usually classified as a spontaneous abortion; those occurring after 20 weeks constitute a fetal demise or stillbirth. Many states use a fetal weight of 350 g or more to define a fetal demise.

Although this definition of fetal death is the most frequently used in medical literature, it is by no means the only definition in use. Even within the United States, the differences in the definitions used are substantial.

In addition, not all states interpret the weeks of gestation in the same manner. In California, 20 weeks’ gestation is worded “twenty utero gestational weeks” and has therefore been interpreted to be 23 weeks from the last menstrual period. (Implantation in the uterus does not occur until 1 wk after fertilization.) Physicians must check the reporting requirements for the state(s) in which they practice.
