A Short-Term Disability denial letter often arrives at the worst possible time. The good news is that a Short-Term Disability appeal is winnable when you have the right structure, the right evidence, and your doctor’s support.
This article gets you started on building all three. Below you will find:
- A sample appeal letter, showing what a complete short-term disability appeal looks like
- A short-term disability appeal letter template using the sample structure that you can adapt to your own claim
- A step-by-step guide for building your appeal, from gathering records through following up after you submit to the insurance company
The insurance company probably told you all you had to do was tell them, “I appeal.” Don’t fall for that. Appeals are not easy, but using this framework can help a lot. Take it section by section. You got this.

Re: Short-Term Disability Claim Number ADI-2026-04-1138
Dear Acme Disability Insurance Company Appeals Department,
I have received your denial letter dated April 10, 2026. This is my appeal of your decision to deny my short-term disability claim.
Background About My Claim
I am a software engineer at Computers R Us, where I have worked since 2019. On February 12, 2026, I felt a sharp pain in my lower back while lifting a heavy box at home. The pain became severe over the following days. On February 15, I had an MRI at Mid-Valley Imaging. The MRI showed a herniated disc at L4-L5 with nerve impingement on the left. My primary care physician, Dr. Marcus Welby, MD, took me out of work as of February 18, 2026 and referred me to Dr. Meredith Grey, an orthopedic specialist.
Since then I have been under continuous medical care. I attend physical therapy with Derek Shepherd, DPT, at North County Physical Therapy two times per week. Dr. Grey specifically directed this frequency. She told me, in her own words, not to overdo it, because more aggressive treatment risks worsening the disc injury. I take a daily prescription muscle relaxer (cyclobenzaprine 10mg) and a daily prescription NSAID (meloxicam 15mg). I am scheduled to receive an epidural steroid injection on May 22, 2026 with Dr. Grey’s pain management partner.
The pain has not resolved. It limits what I can do every day. I cannot stand or walk for more than fifteen minutes without significant pain. I cannot sit for more than thirty minutes without needing to lie flat. I cannot lift more than ten pounds. I cannot bend at the waist or twist my torso without sharp pain that radiates down my left leg. On roughly half of all days, the pain is severe enough that I spend most of the day in bed.
Evidence That Supports My Claim
Attached to this letter are the following records and documents, in addition to the records you already have in my claim file:
- MRI report dated February 15, 2026, from Mid-Valley Imaging
- Orthopedic consult note from Dr. Meredith Grey, March 5, 2026
- Physical therapy progress notes from Derek Shepherd, DPT, covering February 22 through May 8, 2026
- Updated office visit note from Dr. Marcus Welby, May 6, 2026
- Symptom journal I have kept since February 18, 2026, documenting my pain levels, the activities I attempted each day, and how my back responded
- Job description for my position at Computers R Us, signed by my manager
Dr. Grey’s March 5 consult note states that I have a “moderate-to-large left paracentral disc herniation at L4-L5 with displacement of the traversing L5 nerve root.” She documented that my “functional capacity is significantly impaired by pain, with prolonged sitting, standing, and lifting all triggering symptom flares.” Her treatment plan calls for “continued conservative management with physical therapy, anti-inflammatory therapy, and epidural injection, with surgical consultation if symptoms have not improved by mid-summer 2026.”
Dr. Welby’s May 6 office visit note states that I am “unable to work in any capacity at this time” and that my “expected return-to-work date is dependent on response to epidural injection and subsequent re-evaluation.”
The Initial Claim Denial Was Incorrect
Your denial letter states: “Although your MRI confirms a herniated disc, the records indicate you remain capable of sedentary work.”
This is incorrect for two reasons.
First, my job is not sedentary. I address that below.
Second, my medical records do not show that I am capable of sedentary work. Dr. Welby specifically wrote that I am “unable to work in any capacity at this time.” Dr. Grey’s note documents that prolonged sitting triggers symptom flares. Sitting is the core function of sedentary work. My documented inability to sit for more than thirty minutes at a time, by itself, rules out sedentary capacity.
My Job Is Not Sedentary
My position is Software Engineer at Computers R Us, working on hardware diagnostic systems. While much of software engineering involves time at a desk, my role specifically requires regular hands-on work with the physical hardware our software runs on. This includes:
- Setting up, calibrating, and tearing down test rigs at workstations and on lab benches
- Lifting and moving testing equipment, including units that weigh twenty to thirty pounds
- Working in cramped server-room conditions to connect, disconnect, and troubleshoot hardware
- Bending and twisting under desks and behind equipment racks to access ports and cables
- Standing for extended periods during hardware deployments and lab runs
I have attached the job description from my employer, which confirms these requirements. The hardware portion of my role is not optional and cannot be reassigned to a colleague while I recover. My employer does not have a sedentary-only equivalent position for which I am qualified.
Beyond my specific job, the medical evidence rules out true sedentary work for me at this time. I cannot reliably sit, stand, or remain in any one position for the durations a sedentary office job would require.
Conclusion
I am asking you to reverse the decision to deny my short-term disability claim and to approve benefits from February 18, 2026 forward, as my condition continues to be evaluated. My medical records support the claim. My job requirements rule out sedentary accommodation. Please reopen my claim.
Thank you for the careful review I trust you will give my appeal. Please contact me with any questions.
Sincerely,
I.M. Hurting

Short-Term Disability Appeal Letter Template
Below is the template the sample above followed. The bracketed italic text marks the spots where you fill in your own information.
Your Name and address
[Name of Your Insurance Company]
Appeal Department
[Insurance Company Appeal Address in your denial letter, often found buried toward the end of the letter, often different from the address at the top of the letter]
[Date you are sending your appeal letter. Make sure this is on or before the deadline given in your denial letter, which is also often buried toward the end of the letter]
Subject: Re: Short Term Disability Claim Number [use your claim number on your denial letter]
Dear [Insurance Company] Appeal Department,
I have received your denial letter dated [date of your denial letter]. This is my appeal of your decision to deny my claim.
Most Short-Term Disability Appeals need four sections:
Background About My Claim
[Explain the context for your claim: what happened, what your health-related restrictions and limitations are, what your required job duties are, and why you were unable to work. Restrictions and Limitations + Required Job Duties You Can No Longer Perform = Your Disability Claim.]
Evidence That Supports My Claim
[Briefly describe the medical records that show the treatment you’ve been getting, any statements from your doctor(s) about what functional restrictions and limitations you have as a result of your medical condition, relevant test results, etc.]
The Initial Claim Denial Was Incorrect Because
[Explain what the denial letter got wrong. Is the disability insurance company missing some of your important medical records? Cherry picking details from your records that are irrelevant? Misstating the requirements of your job?]
Attachments Included with This Appeal
[You can submit an appeal without additional evidence, but in order to WIN your appeal, you need to have additional evidence that supports your claim. List any additional medical records, doctor letters of support, and any other new evidence you are submitting with your appeal. Send complete office visit notes that record an examination of you plus a diagnosis and treatment plan, NOT “After Visit Summary” records that just list your vitals and prescriptions. If you are not sure whether the insurance company already has a copy of something, send it again. Even if they did a terrible job getting your medical records to evaluate your claim, it is ultimately your responsibility to make sure they have all the proof of your claim that you want them to consider.]
Please contact me at [list your phone number(s) and email address] if you have any questions or need any additional information.
Sincerely,
[Sign your letter, gather all your attachments, keep copies of everything, and send to the insurance company prior to the deadline.]
How to Build Your Appeal Letter Step by Step
The sample shows you what to aim for. The template shows you the structure. This last section walks you through the work of actually putting your own appeal together.
Step 1: Get your doctor on board first.
The single most important factor in winning a Short-Term Disability appeal is support from your treating doctor. Insurance companies set up their claim evaluation to either agree or disagree with what your doctor says. If your doctor will not say you are disabled, the insurance company will lean on that and deny your claim. If your doctor does support your disability, the insurance company may still deny by claiming “we reviewed your medical records and found no support for your doctor’s opinion.” But that gives you a real argument to make on appeal.
If you have not seen your doctor recently, make an appointment now. If you cannot get in soon, an Urgent Care visit can at least document the symptoms keeping you out of work. The most important thing is that your inability to work shows up in the medical record, in a doctor’s own words.
When you talk to your doctor about your appeal, ask them to write a short statement that says:
- They have read your denial letter
- They disagree with the decision to deny your claim
- The specific restrictions and limitations your condition causes
- Why those restrictions prevent you from doing your job
- Your current treatment plan and prognosis
This statement is one of the most important attachments you can include with your appeal.
Step 2: Read the denial letter closely to understand what went wrong.
Most denial letters are written in language that is hard to follow, especially when you are reading one for the first time. The letter is supposed to tell you exactly why your claim was denied. In practice, many denial letters are vague, almost as if they were designed to make you give up.
Read the letter slowly. Look for the specific reason for denial. Common ones include “insufficient medical evidence,” “no objective findings,” “you remain capable of sedentary work,” or “subjective symptoms not supported by examination.” Each of these is a different argument that calls for a different response in your appeal.
If you cannot tell what your denial letter is really saying, send it to us. We will read it for free and explain what the insurance company actually means in plain language. Request a free Denial Letter Review.
Step 3: Gather your evidence.
For the appeal, you should not rely on the records the insurance company already has. Request your own copies of your medical records directly from your providers. Read through them yourself first to make sure they support your claim, then send them with your appeal as numbered attachments.
Useful types of evidence to include with your appeal:
- Your full medical records covering the period of disability, including office visit notes, test results, imaging reports, and physical therapy notes
- A statement from your treating doctor (as described in Step 1)
- A symptom journal you keep daily, recording your pain levels, the activities you tried, and how your body responded. Insurance companies often dismiss subjective symptoms like pain or fatigue. A daily journal makes those symptoms concrete and trackable.
- A copy of your job description, especially if the insurance company seems to have a wrong understanding of what your work involves
- Letters from family, friends, or colleagues describing how your condition has affected what you can do
- Anything else that helps prove your claim. We have submitted photos of injuries, videos of clients trying to perform daily activities, manuals showing what claimants need to lift at work, and other materials. If it helps, send it.
Step 4: Write your appeal letter using the template above.
The template earlier in this article shows you the four core sections every appeal letter should have. Adapt it to your own situation, drawing from the sample for tone and structure. Write each section in plain language. Be specific. Use dates, provider names, and quoted language from your medical records wherever you can.
Once you have a draft, set it aside for a day if you have time. Then read it through and ask: does this letter tell the story of why I cannot work, supported by clear evidence? If yes, you are ready to send.
Step 5: Send it on time and confirm receipt.
Your denial letter will state your appeal deadline. Send your appeal before that deadline. If you email it, keep the confirmation email. If you fax it, keep the fax confirmation page. If you mail it, use a service that confirms delivery. FedEx and UPS do this automatically. USPS requires you to pay extra for tracked delivery.
Keep copies of everything you send. You may need them later.
Step 6: Stay engaged after you submit.
Submitting your appeal feels like a finish line. It is actually the start of the next phase. While the insurance company reviews your appeal, they may send you new reports to comment on, request additional information, or contact your doctor for clarification. You have to respond to all of these, on time, even when you do not feel up to it. Persistence is what carries appeals across the finish line.
A Final Word
A Short-Term Disability claim denial is not the end of the line for your claim. With the right structure, the right evidence, and your doctor’s support, we have seen so many STD appeals succeed. But they all have one thing in common: they are built deliberately on a strong foundation. They do not rely on the kindness of the insurance company!
If you would like help thinking through your claim, send us a copy of your denial letter for a free review. We will read it carefully and explain what the insurance company is really arguing, what you are up against, and what your strongest path forward looks like. Request your free Denial Letter Review. It really is free, and there’s never any obligation to continue working with us.
