Laparoscopic Nissen Fundoplication and EGD

Physician performs at the same surgical setting a laparoscopic nissen fundoplication with hiatal hernia repair and EGD. An EGD is performed prior to starting the lap nissen fundo and an EGD is performed afterwards. I understand the EGD after the procedure is not billable but would the EGD done prior to starting the lap nissen be billable? There is not a separate diagnosis for the EGD.
