An appeal is a formal request for review of a decision made by your Original Medicare, Medicare Advantage, or Part D plan. If you were denied coverage for a health service or item, you may appeal the decision.
Before you start your appeal, make sure you fully read all the letters and notices sent by Medicare and/or your plan. Call 1-800-MEDICARE or your private health or drug plan to learn why your coverage is being denied, if the information was not provided. Your appeal letter should address the reason(s) for denial stated by Medicare or your plan. You can strengthen your appeal by including a letter from your doctor in support of your appeal.
There is more than one level of appeal, and you have the right to continue appealing if you are not successful at the first level. Be aware that at each level there is a separate timeframe for when you must file the appeal and when you will receive a decision. Make sure to file each appeal in a timely manner. If there is a reason you cannot submit your appeal within the timeframe, see whether you are eligible for a good cause extension. Otherwise, your appeal may not be considered.
Keep in mind that an appeal is different from a grievance. A grievance is a formal complaint that you file with your plan.
