Your initial application is your best chance to get approved quickly. Advocate helps you file a stronger first claim or strengthens one you've already started.

Nearly 65-70% of SSDI initial applications are denied. Most denials aren't because the claimant doesn't have a qualifying condition. They happen because of preventable mistakes on the application itself.

Most initial SSDI denials happen because of:
The good news: a stronger initial application is the fastest, cheapest path to approval. Fixing these issues before you file saves you months, sometimes years, of appeals.

Get EvaluationThe SSDI application is more than 15 pages of forms, plus medical records, work history, and detailed descriptions of how your condition affects your daily life. Small errors have big consequences. Advocate's team of case managers and disability representatives file thousands of applications and know what the Social Security Administration (SSA) is looking for at the initial stage.
Our team will help you:
You focus on your health. We handle the paperwork, deadlines, and SSA procedures.

Getting started is fast and free. We stay with you throughout the process to give your claim the best chance of success.
You don't have to start from zero to work with Advocate. Most of the people we help are already in the middle of the process.

If you've started an application but haven't submitted it yet: We'll review what you've entered, flag gaps in your medical evidence, and help you finish strong before you hit submit. Even small wording changes can affect how the SSA reads your claim.
If you've already submitted your application: We can still step in while it's under review. We'll represent you with the SSA, submit additional medical evidence, respond to requests from your state's Disability Determination Services examiner, and make sure nothing important gets missed. The earlier we're involved, the more we can do, so don't wait for a denial to ask for help.
If your claim has already been denied: You have 60 days from the date on your denial letter to file a Request for Reconsideration. Visit our reconsideration page or the full SSDI appeal process guide to learn more.

About the SSDI Initial Application
You qualify for Social Security Disability Insurance (SSDI) if you have a medical condition expected to last at least 12 months (or result in death) that prevents you from engaging in substantial gainful activity, and you have enough work credits from recent employment. Most adults need 40 credits total, with at least 20 earned in the last 10 years, though younger workers can qualify with fewer. If you don't have enough work credits, you may qualify for Supplemental Security Income (SSI) instead, which is based on financial need rather than work history.
You can file your initial SSDI application three ways: online at SSA.gov, by phone at 1-800-772-1213, or in person at your local Social Security office by appointment. Most claimants file online because it lets you save your progress and attach documents. If you'd like help filing (whether you've already started or not), request a free evaluation and Advocate's team will walk you through each step.
You'll need: your Social Security number, birth certificate, information about all medical providers you've seen for your condition (names, addresses, dates), a list of medications and dosages, your W-2s or self-employment tax returns for the last year, and a detailed history of the jobs you held in the 15 years before you became unable to work. The more complete this information is when you file, the less likely the SSA is to delay your case with follow-up requests.
Initial SSDI decisions typically take 3 to 6 months, though some cases take longer depending on how quickly the SSA and your state's Disability Determination Services (DDS) office can gather your medical records. Check out how long your state takes and their initial application rate. Cases involving a Compassionate Allowance condition (certain cancers, ALS, and other severe diagnoses) can be decided in weeks.
Yes. Many claimants file what's called a 'concurrent claim' for both SSDI and SSI. SSDI is based on work credits; SSI is based on financial need. If you're not sure which you qualify for, Advocate's team will evaluate your eligibility for both during your free consultation.
A denial is not the end of your claim. Nearly 65-70% of initial applications are denied, and many claimants are approved at later stages. You have 60 days from the date on your denial letter to file a Request for Reconsideration. If that's denied, the next step is an ALJ hearing, where approval rates are significantly higher.
It isn't required, but it's often worth it. Having experienced representation at the initial stage means fewer errors, stronger medical evidence, and a better chance of being approved without going through months of appeals. Most disability advocates, including Advocate, work on contingency, which means you pay nothing unless you win, and any fee is federally capped at 25% of your back pay (maximum $9,200).
As soon as possible. SSDI benefits can be paid retroactively for up to 12 months before your application date (subject to the five-month waiting period), but the longer you wait, the more back pay you may lose. If your condition is expected to keep you from working for at least 12 months, don't wait. Start your application now.
