Self Pay Question

Hello Everyone, I currently live just outside of Knoxville Tennessee. I work as a Registered Nurse and have a Highmark BCBS through my employer. Our plan states they will not cover the actual bariatric surgery but will cover complications related to the procedure. Anyone had gastric sleeve done in the south eastern US where they had to self pay for the procedure? Any tips? Any doctor recommendations? I have been debating the surgery for years and just really feel like I need to move forward with my decision.
