What an appeal letter does and what it must contain

An appeal letter is your written statement to your long-term disability (LTD) insurer explaining why you believe their denial or termination decision was wrong. It is not a formal legal document—it is a persuasive letter that goes into your claim file and is reviewed by the same insurer or, in some cases, by an independent reviewer.

Your letter must do three things: state clearly what decision you are appealing, explain why that decision conflicts with the policy language or the medical evidence, and provide new or overlooked information that supports your case. The insurer will compare your letter against the original denial letter, your medical records, and the policy itself. If your letter straightforward repeats what you already submitted, it will not change the outcome.

Most LTD policies give you between 30 and 90 days from the denial date to file a written appeal. Check your denial letter for the exact important date and the address where appeals go—this is often different from the claims address. Missing the important date usually closes your right to appeal within the insurance process, though you may still have legal options outside it.

Key Takeaways

  • Your appeal letter must identify the specific decision you are challenging and explain exactly why it was wrong, not straightforward disagree with it.
  • Include new medical evidence, test results, or statements from your doctors that directly contradict the insurer's reason for denial.
  • Address the insurer's stated reason for denial point by point—if they said your condition is not severe enough, show why it is; if they said you can work, show why you cannot.
  • Keep the letter under three pages, use plain language, and send it by a method that creates a record (certified mail or email with read receipt).
  • If your appeal is denied a second time, you may have the right to external review or legal action, depending on your policy and state law.

Understanding why the insurer denied your claim

Before you write, you must understand the exact reason the insurer gave for the denial. Read your denial letter carefully and look for the stated reason. Common reasons include: your condition does not meet the policy definition of disability; you have not been disabled long enough to trigger benefits; you can perform the duties of your own occupation or any occupation; medical evidence does not support the severity you claim; or you failed to provide required medical records or forms.

The denial letter should cite the specific policy language or medical finding that led to the decision. If it does not, request a detailed explanation in writing before you appeal. You cannot effectively challenge a decision you do not fully understand. Write to the claims department and ask them to explain in detail which policy requirement was not met and which medical evidence led to that conclusion.

Once you know the reason, your appeal strategy becomes clear. If the insurer says your condition is not disabling, you will need medical evidence showing it is. If they say you can work, you will need evidence showing you cannot. If they say you did not provide required information, you will provide it now. Your letter must address the insurer's stated reason directly—not argue around it.

Gathering medical evidence before you write

The strongest appeal letter includes new or overlooked medical evidence. Contact your treating doctors and ask them to write a letter or statement supporting your claim. The statement should address the specific reason for denial. If the insurer said your condition is not severe enough, ask your doctor to explain why it is severe and why it prevents you from working. If the insurer said you can perform your job duties, ask your doctor to explain what job duties you cannot perform and why.

Request recent test results, imaging, lab work, or clinical notes that support your position. If you have seen a specialist since the denial, get their records. If you have been hospitalized, had surgery, or started a new treatment, include documentation of that. The insurer may not have had this information when they made the original decision.

Do not include every medical record you have ever received. Instead, select the records that directly address the reason for denial. A 200-page medical file attached to your appeal is harder to review than a focused set of five recent records that clearly show why you cannot work. Organize the records in chronological order and label them so the reviewer can find the key passages.

Writing the letter itself

Start with your name, policy number, and claim number at the top. Address the letter to the appeals department (use the address from your denial letter). Write the date you are sending it.

In the first paragraph, state clearly what you are appealing. Example: "I am appealing the denial of my long-term disability claim dated [date]. The denial stated that my condition does not meet the policy definition of total disability. I believe this decision is incorrect because [brief reason]."

In the second section, address the insurer's stated reason for denial point by point. If they said you can perform your job duties, explain why you cannot. Use specific examples: "I worked as a software developer. My condition causes severe pain when I sit for more than 30 minutes. I cannot perform the essential duty of sitting at a computer for eight hours per day. My doctor's letter, attached, confirms this limitation." Do not argue that the decision is unfair or that you deserve benefits. Argue that the decision does not match the policy language or the medical facts.

In the third section, present new or overlooked evidence. Explain what it shows and why it matters. Example: "Since the denial, I have had an MRI that shows [finding]. This directly contradicts the insurer's statement that my condition is not severe. My doctor's letter, attached, explains why this finding means I cannot work."

Close by restating your position and asking for reconsideration. Keep the letter to two or three pages. Use plain language. Do not use legal jargon or make threats. Do not be angry or emotional, even if you are. The reviewer is reading dozens of appeals; a clear, factual letter is more persuasive than an angry one.

What to include and what to leave out

Include: your policy number and claim number; the date of the denial; the specific reason the insurer gave for denial; your response to that reason; new medical evidence or statements from your doctors; dates and specifics (not "I cannot work" but "I cannot sit for more than 30 minutes"); and a clear request for reconsideration.

Leave out: personal stories that do not address the denial reason; complaints about the insurer or the claims process; arguments about fairness or what you deserve; medical records that do not relate to the denial reason; and anything that sounds like a legal threat. The insurer is not moved by emotion or anger. They are moved by evidence that contradicts their stated reason for denial.

Do not rewrite the denial letter or quote it at length. Instead, acknowledge the reason they gave and explain why it is wrong. Example: "The insurer stated that I can perform the duties of my occupation. However, my occupation requires [specific duty]. I cannot perform this duty because [specific reason supported by medical evidence]."

Sending your appeal and what happens next

Send your letter and supporting documents by certified mail with return receipt, or by email to the appeals address with a read receipt request. Keep a copy of everything you send. Do not send originals of medical records; send copies. Write down the date you sent the appeal and the tracking number if you used mail.

The insurer must respond to your appeal within a set timeframe—usually 30 to 60 days, though this varies by policy and state. Some policies require faster responses for urgent claims. Check your denial letter for the response important date. If the insurer does not respond by that date, you may have the right to file a complaint with your state insurance commissioner.

The insurer will either uphold the denial, reverse the decision and award benefits, or ask for more information. If they ask for more information, provide it promptly. If they uphold the denial a second time, you may have the right to external review (in some states) or to pursue a legal claim. An external review is conducted by a medical professional outside the insurance company. A legal claim means filing a lawsuit, which usually requires an attorney.

Common mistakes to avoid

Do not miss the important date. Once the appeal period closes, you lose the right to appeal within the insurance process. Mark the important date on your calendar and send your appeal at least one week before it expires.

Do not assume the insurer has all your medical records. Even if you sent them during the original claim, send them again with your appeal. Clearly label which records are new and which address the specific reason for denial.

Do not write an emotional or angry letter. The reviewer is not the person who made the original decision. They are reading your letter to decide whether the original decision was correct. Anger makes your letter less persuasive, not more.

Do not straightforward repeat what you said in your original claim. Your appeal must include new information or a new explanation of why the original decision was wrong. If you have nothing new to say, your appeal will likely fail.

Do not hire someone to write your appeal unless they are a lawyer or disability advocate licensed in your state. Many online services claim to write appeals but have no legal standing and may give you bad information.

When to consider legal help

If your appeal is denied a second time, or if the insurer terminates your benefits after you have been receiving them, you may want to consult a disability attorney. Many attorneys work on contingency, meaning they take a percentage of any money recovered rather than charging you upfront. A consultation is usually free or low-cost.

An attorney can review your policy, the insurer's decision, and your medical records to tell you whether you have a legal claim. They can also file a lawsuit if necessary. The rules for suing an insurer vary by state and by whether your policy is governed by federal law (ERISA). An attorney who handles disability claims in your state will know these rules.

You do not need an attorney to write your first appeal. But if you have been denied twice, or if the amount of money at stake is large, legal information is worth considering.

Frequently Asked Questions

How long should my appeal letter be?

Two to three pages is ideal. The reviewer needs enough detail to understand your position and see how you are addressing the insurer's stated reason for denial, but not so much that key points get lost. If you need more space, use an attachment for medical records or a detailed timeline, but keep the letter itself concise.

Should I include a letter from my doctor with my appeal?

Yes, if possible. A statement from your treating doctor that addresses the specific reason for denial is one of the strongest pieces of evidence you can include. Ask your doctor to be specific: not just "the patient is disabled" but "the patient cannot sit for more than 30 minutes due to pain, and sitting is essential to their job as a software developer."

What if I do not have new medical evidence since the denial?

You can still appeal if you have a new explanation of why the original decision was wrong. For example, if the insurer said you can perform your job duties, you can explain in detail why you cannot, even if your medical records have not changed. But new medical evidence is stronger than a new explanation, so if you can see a doctor and get updated records, do so before appealing.

Can the insurer deny my appeal without reading it?

No. The insurer must review your appeal and respond in writing with their decision. If they deny your appeal without addressing the points you raised, that may be grounds for a legal claim. Keep a copy of your appeal and their response so you can show an attorney if needed.

What happens if I miss the appeal important date?

You lose the right to appeal within the insurance process. However, you may still have legal options. Some states allow you to file a complaint with the insurance commissioner, and you may be able to file a lawsuit even after the appeal period closes. Consult an attorney as soon as you realize you missed the important date.
