This letter is meant to give you an opportunity to seek a review of the decision by the health insurance company.

    Steps for Writing an Effective Appeal Letter

    This is a formal letter and must follow the official business letter format. With the steps provided below, you can adequately write one using the proper format and the required details:

    1. Start with the basics

    The first part of your letter is about the basic details of your issue to help the insurance company understand your appeal. You should include your name as it appears in your health policy, the policy number on the insurance card, the policyholder’s name, your contact details, such as your phone number and mailing address, and the health care provider’s name and contact details.

    You also need to include the date of denial, the details of what was denied, and the reason for this denial. Finally, if you are writing the letter on behalf of someone, ensure you include the patient’s name.

    2. Include details of the case 

    It would be best if you had body paragraphs containing a detailed explanation of the medical situation. Your information should be specific, include all details related to the situation, and provide all the necessary information that will propel the insurance company to change its verdict to a positive one.

    Brief introduction

    This will include your full name, age, primary diagnosis, description of the claim, and why you believe the insurance company handled your claim unfairly.


    I am Kevin Henry, 55 years old. I was diagnosed with heart failure that resulted from blocked arteries. I need heart bypass surgery, and your insurance company denied my claim. Therefore, I am writing this letter regarding claim number 54000, where my claim was deemed not medically necessary. However, this is to inform you that the surgery is essential to reduce the frequent hospital trips required to manage the condition. In addition, the surgery is way cheaper than any other medical procedure.

    Description of medical conditions

    The next step is to provide a detailed description of your medical conditions and the relevant medical procedure or item that you need.


    My heart failure diagnosis results from the obesity that I am currently struggling with. I have been in a program to help me deal with this condition. However, due to my obese condition, I tend to have frequent hospital trips to help manage my condition. The danger of heart attacks and strokes is always present in my health condition, which will further complicate my situation and affect my quality of life.

    Explain the importance of the treatment

    You should then explain the benefits you will get from getting the medical procedure or item.


    With the heart bypass surgery, I will be able to reduce costly hospital visits due to coronary angioplasty aimed at unblocking my arteries. The surgery will improve my health, allowing me to lead a more active lifestyle and helping me with my obesity. With a healthy heart, I can quickly lose weight and avoid the threat of a stroke or heart attack.

    Followed by mentioning what will happen if you do not receive the medical item or procedure and highlighting how costly it will be.


    If the verdict is not changed and I cannot receive my heart bypass surgery, my hospital visits will increase due to my blocked arteries. This might lead me to stay at the hospital for an extended period and require more medical attention due to the higher risks of heart attacks, strokes, and even kidney failure. All this together would lead to higher medical costs as compared to the costs of heart bypass surgery. 

    Attach medical records

    Ensure that you attach your medical records in a way that is easy for the insurance company to understand. You can also support your claim by providing more details about your medical condition through brochures, published research articles, and treatment guidelines by various medical organizations.

     Close the letter

    Summarize your arguments by highlighting the most crucial details.


    To avoid further hospitalizations, I should receive my heart bypass surgery as soon as possible. Once I have recovered, my heart bypass surgery reduces the chances of any other costly procedures or lengthy hospital stays.

    Express your gratitude at the end of your letter.


    I am grateful for your time and consideration of this sensitive matter. Thank you very much.

    The final part of the letter includes a complimentary closing and the signing of the appeal letter.


    3. Ensuring it reaches the recipient 

    The final step is to ensure that it is sent to the correct address and on time. Whether via fax or snail mail (certified mail), ensure that you retain the confirmation message or the return receipt (proof of delivery) until the appeal process is over. Do not forget to keep a copy of the letter for your records.

    Sample Letter

    Utilize the following appeal letter sample as a resource to construct formal correspondence with your insurance company, articulating your concerns with precision and courtesy. 


    Dear Insurance Company,

    I am writing to appeal the recent decision regarding my insurance claim (Claim Number: 123456789). My name is Jane Doe, and I have been a loyal customer of Acme Insurance for over ten years. This claim is of utmost importance to me, as it involves a situation that has significantly impacted my life.

    On March 15, 20XX, I was involved in an unfortunate incident that resulted in substantial damage to my property. As per our policy agreement (Policy Number: ABC-987654321), I am entitled to coverage for such damages. I promptly filed the claim, providing all necessary documentation, including photographs of the damage, a police report, and an assessment from a licensed contractor.

    However, to my dismay, the claim was denied on the grounds of insufficient evidence of damage. This decision was unexpected, as I believe I have provided ample proof to validate my claim. The contractor’s assessment clearly outlines the extent of the damage, aligning perfectly with the terms of my policy. I kindly request a thorough re-evaluation of my claim, considering all the evidence I have submitted.

    I am confident that upon a comprehensive review, you will find that the claim is justified and falls well within the coverage scope of my policy. Your prompt attention to this matter will be greatly appreciated. Please feel free to contact me at (555) 123-4567 or janedoe@email.com for any further information or clarification.

    Nine Essential Strategies to Ensure Success with Medical Claims

    When writing an appeal letter, there are nine essential strategies that you can use to ensure that the insurance company deals with your claim fairly. Observing the following strategies will help you write a proper and effective letter to increase your chances of getting a favorable new verdict.

    Here are the nine crucial strategies you should use when writing your letter:

    Draw attention to financial benefits 

    Insurance companies, just like any other organization, are always interested in making profits. Therefore, when writing your appeal letter to them, your focus should be on showing the insurance company how changing the denial claim will help them save money.  The aim is to provide clear and distinct factual examples of how they will benefit from approving the denied claim.


    You can highlight that the item or procedure you want them to cover will reduce the number of hospital visits, lengthy hospital stays, and other procedures that might be more expensive than your original request, which means they will eventually save money.

    Check for errors

    In some cases, insurance companies might deny your appeal because of the mistakes in your letter. It is, therefore, essential to check for errors and correct them to ensure you have the correct information. It would be best to avoid making simple mistakes like writing the wrong identification number to avoid having your appeal turned down by the insurance company.

    Check for spelling and grammar mistakes

    Before sending your appeal letter, ensure that you proofread your letter to correct any spelling and grammar mistakes. In most cases, you may need to check if you have correctly used the right format and written the medical terms, names, claim numbers, and policy identification numbers correctly. Spelling and grammar mistakes make the letter non-serious and might impact your chances of a favorable answer. 

    Involve a medical professional

    Since it is about your medical situation, it will be good to strengthen your appeal letter by inviting your doctor or any other medical professional to lend support to your claim. You can write a good letter with the help and support of your doctor. 

    Keep in mind that waiting for the doctor to write the letter themselves might take too long. In most cases, the medical personnel are too busy, and the best way to avoid further delay is by writing the letter yourself and emailing it to the doctor to lend his support by adding some information on your medical situation. Ensure that the doctor sends back the accurate letter along with any other required documentation.

    Attach medical records (if needed)

    If possible, ensure that you attach the medical records, as this type of documentation will support your appeal. Apart from your medical records, you should also attach any other medical documentation that supports the claim you have made in your letter.

    For instance

    You can include a brochure with information about the importance of the medical procedure the insurance company denied you. A copy of the insurance claim denial should also be attached.

    Accuracy and sticking to facts 

    The insurance company cares more about the case facts than a sob story about your financial situation. So instead of mentioning how sad you are about your health or your financial struggles, try to focus on writing accurate facts about your case.

    Approach the case manager

    Most insurance companies have case managers who can be approached, especially if your case involves a child with multiple medical issues. A case manager will help you process your appeal once you have written your letter. In addition, you can send them a photo of your child to keep them motivated when working on the case.

    Appeal to the HR department

    Another important strategy you should implement is to appeal to the HR department. This is because the human resources department will hold negotiations with the insurance firm and assist you in changing the verdict. So reaching out to the HR department will improve your chances of getting a favorable result.

    Look for all possible solutions 

    In case your internal appeal is denied by the insurance company, you can request a review, according to the ACA. A third party usually conducts these negotiations instead of the insurance company. The health insurance company must inform the third party why your appeal was denied and highlight your rights to an external appeal. Depending on your state, you can also get help from the Consumer Assistance Program (CAP).

    Wrapping Up

    An appeal letter is a formal letter that will be needed if the health insurance company has unfairly dealt with your claim. This is the first step in starting your appeal process once you have confirmed that the state laws require insurance companies to cover your specific medical item or procedure. Ensure that you follow the steps and strategies provided in this article to write a proper and effective letter.
