Hi Stacy,
I'm not sure how you go about it, but I would suspect that a genetic counselor would be the place to start. There is some information at this site:

As far as the insurance problem, it's tricky. You would have to pay for the procedure out of your own pocket, to keep your insurance company from finding out. And according to the website referenced above, the cost is about $50,000. However, that was in 1996, it certainly could be somewhat cheaper by now.
I think you could discuss it with your OB-Gyn without having her note it in your records, if you asked.
Good luck!
