What goes in a long-term disability appeal letter
An appeal letter for long-term disability is a written request to your insurance company asking them to reconsider a denial. It should restate your medical condition, explain why you believe the denial was wrong, and include any new evidence—like updated doctor's notes or test results—that supports your case. The letter goes to the specific address your denial letter provided, usually within 180 days of the denial date.
The insurance company will read your letter alongside the original claim file. They are looking for reasons the denial might have been based on incomplete information, a misunderstanding of your condition, or a mistake in how they applied their own policy. Your job is to make that case clearly and directly, without anger or argument.
Key Takeaways
- Your appeal letter must arrive within the important date stated in your denial letter, which is usually 180 days but can vary by plan.
- Include your policy number, claim number, and the date of the denial so the insurance company can find your file when ready.
- Attach new medical evidence—recent doctor's letters, test results, or treatment records—rather than repeating what was already in your original claim.
- Explain specifically which part of the denial you disagree with and why, using plain language rather than medical jargon.
- Send your letter by certified mail with return receipt so you have proof it arrived on time.
How to structure your letter
Start with your name, address, phone number, and the date at the top. Then add your policy number and claim number exactly as they appear on your denial letter. Address the letter to the appeals department at the address provided in your denial—not to a general company address.
Open with a single sentence stating that you are appealing the denial of your long-term disability claim. Then move directly to the body of the letter. Do not apologize for appealing or explain why you are writing. The insurance company expects appeals; they are part of the normal process.
Keep paragraphs short—three to four sentences each. Use a standard font like Times New Roman or Arial in 11 or 12 point. Single-space the letter and leave one blank line between paragraphs. The goal is readability, not length.
What to say about your medical condition
Describe your condition in the way your doctors describe it. If your doctor says you have "severe degenerative disc disease with radiculopathy," use that language. Do not simplify it to "back pain" or exaggerate it. The insurance company has your medical records; they will notice if your description does not match what your doctors wrote.
Explain how your condition prevents you from doing your job. Be specific: instead of "I cannot work," write "I cannot sit for more than 20 minutes without severe pain, and my job requires eight hours at a desk." Instead of "I am too tired," write "My medication causes drowsiness that makes it unsafe to drive, and I cannot perform my duties as a delivery driver." The insurance company needs to understand the connection between your medical condition and your inability to work.
If your condition has worsened since your original claim, say so and explain how. If you have had new tests, surgery, or treatment, mention it. This is where new medical evidence becomes important—your letter points to it, and the attached documents prove it.
Addressing the reason for the denial
Your denial letter will state why the claim was denied. Common reasons include: the condition is not severe enough, you can still do your job, the condition is not covered under the policy, or the medical evidence is insufficient. Your letter must address the specific reason given in your denial.
If the denial says your condition is not severe enough, explain why it is. Quote your doctor's notes if they support you. If the denial says you can still do your job, explain why you cannot—be concrete about the physical or mental demands of your work and how your condition prevents you from meeting them.
If the denial says the condition is not covered, review your policy language carefully. If you believe the condition should be covered, explain why. If the denial says medical evidence is insufficient, attach new evidence. Do not argue with the insurance company's interpretation of the policy; instead, show them information they did not have before.
What new evidence to include
Attach copies of documents that were not in your original claim file or that provide more recent information. These might include: a letter from your treating doctor stating that you remain unable to work, recent lab results or imaging reports, a functional capacity evaluation, records from a specialist you saw after your original claim, or a letter from your employer confirming the duties of your job.
Do not attach your entire medical file. Instead, attach only the documents that directly support your appeal. If your file is large, include a one-page list of what you are attaching and why. For example: "Attached: Dr. Chen's letter of March 15, 2024, confirming that my condition has worsened and that I remain unable to work full-time."
If you have a letter from your doctor specifically written for the appeal, that is the most powerful evidence. Ask your doctor to write a brief letter stating that you remain unable to work and why, and to reference the specific reason given in the denial if possible.
Tone and language to use
Write in a respectful, factual tone. You are not angry at the insurance company; you are providing information they need to make the right decision. Avoid phrases like "you made a mistake" or "this is unfair." Instead, write "I believe the denial was based on incomplete information" or "the medical evidence shows that my condition prevents me from working."
Use "I" statements: "I cannot perform the duties of my job" rather than "my condition makes work impossible." Avoid medical jargon unless your doctors use it. If you do use a medical term, explain it briefly: "I have neuropathy, which means nerve damage that causes pain and numbness in my hands."
Do not make threats or mention hiring a lawyer in the letter itself. If you do hire a lawyer, they will handle communication with the insurance company from that point forward.
How to send your letter and what happens next
Make two copies of your complete letter and all attachments. Keep one copy for your records. Send the other by certified mail with return receipt requested to the appeals address on your denial letter. Write down the certified mail tracking number and the date you mailed it.
The insurance company will send you a receipt acknowledging that your appeal was received. Keep this receipt. The company then has a set amount of time—usually 30 to 60 days, depending on your plan—to review your appeal and send you a decision. Some plans allow longer if they need more medical information.
If the company requests additional information during the appeal, provide it promptly. If they ask your doctor a question, contact your doctor right away and ask them to respond directly to the insurance company.
Frequently Asked Questions
What if I miss the important date to appeal?
Contact the insurance company when ready and ask whether they will accept a late appeal. Some plans allow extensions if you have a good reason for the delay. If they refuse, you may have other options depending on your plan and state law, but waiting makes your situation harder. Do not delay.
Should I call the insurance company before sending my letter?
You can call to confirm the correct mailing address and the important date, but do not discuss the merits of your case over the phone. Keep all substantive communication in writing so you have a record of what you said. If the company offers to discuss your appeal by phone, ask them to send you an email confirming what was discussed.
Can I appeal more than once?
Most plans allow one appeal to the insurance company itself. If that is denied, you may have the right to an external review by an independent doctor, depending on your plan and state law. Your second denial letter will explain what options are available to you.
Do I need a lawyer to write my appeal letter?
You can write it yourself. Many people do. A lawyer can help if your case is complex or if the insurance company has denied your appeal and you want to pursue further action, but you do not need one to write the initial appeal letter.
What if the insurance company asks for more medical information?
Provide it as quickly as you can. Contact your doctor and ask them to send the requested records directly to the insurance company. Keep a copy for yourself and note the date you requested the information and the date your doctor sent it.
