How to appeal when your coverage is denied

From coverage denial to external appeal

The insurance company denies your coverage.

Insurance companies are required to tell you why they’ve denied your claim and how you can appeal their decisions. Sometimes, a denial may be because of an error in how the claim was submitted. In other cases, the treatment or medication requires preauthorization or is not covered under your plan.

You submit an internal appeal.

Contact your insurance company for details on its appeals process or consult your denial letter for instructions on how to file an appeal. Submit your appeal and wait about 30 days for a response (times may vary by insurer). Note: Some plans may have multiple levels of internal appeals. This may include a peer review, during which the plan will contact a doctor who is not involved in your care to review the claim.

If the internal appeal is denied, consult your current plan to understand your options. The next step may be an external appeal.

When your health insurance company denies your internal appeal, the next step may be to request an external appeal to an independent review organization. There must be 2 appeals denied prior to beginning the external appeal process. This process is available for individual and employer-sponsored health insurance plans.

The external appeals process varies by state. Please click on your state in the map below or select from the drop-down menu to get the information that is applicable to you.

Tips for the appeals process

Work with your healthcare provider team.

  • Your healthcare provider team can support you throughout the appeals process—they may even file the appeal on your behalf

  • Request a letter of medical necessity from your healthcare provider, which should include the reasons why it is medically necessary for you to get the care they have provided/recommended. Please click here to download a sample letter of medical necessity for reference

Dot your i’s and cross your t’s.

  • Include all the information requested by your insurance company (eg, name, identification number, name of provider, dates of service, claim reference number, etc)

  • Complete forms exactly as requested to avoid rejections due to small errors

Stay organized.

  • Get a copy of your records from your insurance company and request any decisions it makes in writing

  • Create a digital or hard copy folder with any documents you send to or receive from your insurance company

  • When contacting the insurer, note the dates and methods of contact, the names of people you talk to, and summaries of conversations

  • Provide any additional resources, including a patient narrative letter. Please click here for a sample patient narrative letter for reference

  • Be mindful of deadlines (see chart below)
