“Fetal death” means a death prior to the complete expulsion or extraction from its mother of a product of conception (irrespective of the duration of pregnancy); the death is indicated by the fact that after such separation, 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. Registration of fetal deaths is subject to the provisions of Division 9, Chapter 4 of the Health and Safety Code.
