WLS Exclusion - Self Pay With Covered Surgery

 Has anyone ever had wls along with another procedure that was covered?  I have BCBS with exclusion for WLS.  I may need gallbladder out and was wondering about doing both at one time.  I was told it would be hard to do in SC R

I know Dr. Byrne will take the gall bladder out, but not sure how you would go about dancing around the insurance company.
