• You may be required to start with your primary care physician.  In some cases,
  he or she is the only one you can ask for a referral to a qualified bariatric surgeon.  Even if you are not required to get a referral, it is a good idea to have the support of your primary care physician.
• Before visiting us, organize your medical records, including your history of dieting efforts.  They will be valuable documents to have at every stage of the approval process.
• Document every visit you make to a healthcare professional for obesity-related issues or visits to supervised weight loss programs.  Document "other" weight loss attempts made through diet centers and fitness club memberships.  Keep good records, including receipts.
• If we recommend weight loss surgery, we will prepare a letter to obtain pre-authorization from your insurance company.  The goal of this letter is to establish the "medical necessity" of weight loss surgery and gain approval for the procedure.  The following information is generally included in the pre-authorization letter:
• Your height, weight and Body Mass Index and any documentation you might have as to how long you have been overweight.
• Simply describing your condition as "morbid obesity" is not enough.  A full description of all your obesity-related health conditions, including records of treatment, a history of medications taken and documentation of the effects these conditions have had on your everyday life is necessary.
• A detailed description of the limitations your excess weight places on your daily activities, such as walking, tying shoes, or maintaining personal hygiene.
• A detailed history of the results of your dieting efforts, including medically and non-medically supervised programs, medical records and records kept of payments to and meetings attended with commercial weight loss programs.
• A history of exercise programs, including receipts for memberships in health clubs.
• Ask your doctor to include information from medical journals regarding
  the effectiveness of weight loss surgery, particularly information showing the control or elimination of obesity-related health conditions.

Thirty days is the standard time for an insurance provider to respond to your request. You should initiate a follow-up if you have not heard from your insurance company in that time.

The Appeals Process
Even if your initial request for pre-authorization is not approved, you still have options available.  Insurers provide an appeal process that allows you to address each specific reason they have given for denying your request.   It is important that you reply quickly. It is also recommended that, at this point, you enlist the help of an experienced insurance attorney or insurance advocate to properly navigate the complexities of the appeal process.  Some insurers place limits on the number of appeals you may make, so it is important to be well prepared and that you clearly understand the appeal rules of your specific plan.
