I am just so very sorry & saddened by all that you have been through...I cannot fathom why any insurance company would deny you, but if you must go through the exploratory lap. first, by all means, let the insurance pay for it and then let them pay for everything else that follows if necessary...
I too had an exploratory lap. in 9/07 due to persistent, suspicious ovarian cysts, bowel problems and horrible lower back pain (my cysts always seem to present as low back pain). At that time, nothing seemed abnormal. My problems worsened after that (not saying that the procedure contributed to it, however, I just kept getting worse and started having very heavy bleeding and more cysts). I finally had my hysterectomy almost a month ago.
With your history, I am betting that the doc will find something, but if indeed it is normal, no one will think you are crazy or went through the procedure for no reason--just look at all you are feeling and have been through
I know how terribly nervous you must be, about the procedure and about being denied the original procedure...just know that we are all here to support you through this and will do everything we can to help you.
I will be thinking of you, and wish you all the best for an uneventful procedure and a speedy recovery--please do keep us posted.
PS: My exploratory may have looked normal to the oncology specialist I had been referred to, but a mere 9 months later, I had adenomyosis and my appedndix was adhered to my pelvic region, as were my intestines on the right side...things really can change.
