Bariatric Surgery Insurance Appeal

Weight Loss Surgery Insurance
Be persistent - The appeals process can take a lot of work, but don't give up!

If you requested pre-authorization for bariatric surgery and receive a denial, APPEAL. As there is usually a time limit to respond, it is important to appeal within a timely manner, but it is also important to respond effectively. When appealing, write a letter that is factual and persuasive, yet pleasant and polite. Keep in mind your goal - approval for weight loss surgery.

Appealing a Medical Necessity Denial - Patient's Letter

Your appeal letter should include:

  • Patient Identification - information used to identify your case, such as your name, policy number, group number, claim number
  • Reason for denial - restate reason for denial as explained in denial letter
  • Brief health history - patient statement of history with obesity, health conditions, previous weight loss attempts, and why bariatric surgery is a necessary treatment
  • Information to correct errors - if it appears the denial was made because of an error, state the correct information, such as wrong surgery or procedure coding error
  • Why you disagree with denial - tell the insurance company why you disagree with their decision, whether due to incorrect or incomplete information, and provide specific, factual information that supports approval of weight loss surgery for treatment
  • Purpose of letter - what you are requesting in your appeal, i.e. that the insurer reconsider the denial and approve coverage for the procedure in a timely manner
