Many insurance companies require excellent documentation of your complete history before bariatric surgery can be approved. Please fill out all of the information given to you, and collect all of your medical records from your physician with proof of supervised weight loss, as well as a physician referral letter if needed (check with your insurance company). We will assist you with the approval process. A list below includes, but is not limited to companies that have approved for either general or bariatric surgery. We will also work with claims for all general surgery cases.
