insurance question

Hello I am new to this site. My husband has had vgs surgery and was approved with no problem from his insurance. I am currently not on his insurance plan but will be added  in november during open enrollment.  I have my own insurance but it does not cover bariatric surgery. I know all of the appointments i must have  prior to surgery.  So my question is  if i attend some of these appointments with my present insurance.   Then later change over to my husbands insurance. Will my new insurance accept  the prior appointments or will i need to do them all over again under my new insurance.  basically i want to get a head start since i know i need at least 3 months with a nutritionist. 

I believe you need to call your husband's insurance and ask them if they will accept it.
