Your best bet is to call the insurance company and see if they have any exclusions or riders on the policy. Ask specifically for the lap-band and the bypass. Or, if you can't get a straight answer (which sometimes you can't) you can always have your family dr submit a letter of medical necessity with the appropriate Diagnosis and Procedure codes for each option and then wait and see what sort of decision comes back from the insurance company. That process can take awhile because insurance companies love to drag their feet! Good luck!
