Can a health insurance company deny benefits after pre-approving and allowing the patient to proceed with surgery?

I was pre-approved and under went weightloss surgery, I am now being told this was an exclusion on my policy after the fact. Can they do this after allowing me to go through with everything by granting me reffereals, and pre-auths. Should they have know I was not eligible for this service and denied it?
