Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are two separate federal programs that provide monthly payments to people with disabilities. While both programs serve people who cannot work due to medical conditions, they have important differences in how they work and who may receive benefits.

SSDI is a program based on work history. To learn about SSDI, you should know that it provides benefits to workers who have paid into Social Security through payroll taxes and become unable to work due to a serious medical condition. The program also covers certain family members of workers receiving SSDI, including spouses and children. As of 2024, approximately 8.1 million people receive SSDI benefits, with an average monthly payment of around $1,550.
SSI, by contrast, is a needs-based program. This means the program considers your current income and resources when determining payment amounts. SSI provides benefits to people with disabilities, blindness, or those age 65 and older who have limited income and resources. Unlike SSDI, SSI does not require a work history. In 2024, about 7.3 million people receive SSI, with an average monthly payment of approximately $943.
Both programs use the same medical criteria to determine disability status. The Social Security Administration defines disability as the inability to work and earn more than a certain amount due to a medical condition that is expected to last at least 12 months or result in death. This definition covers a wide range of conditions, including physical disabilities, mental health conditions, intellectual disabilities, and other serious medical issues.
Understanding which program may apply to your situation is an important first step. Your work history, current income, and resources will influence which program structure suits your circumstances. A free informational guide on representation options typically explains these program differences so you can understand what information you may need to gather if you decide to pursue further steps with Social Security.
When dealing with Social Security Disability matters, many people choose to work with representatives who understand the system. These representatives come in different forms, and each has different qualifications and ways of working with people.

Attorneys who practice Social Security law have gone through law school and are licensed to practice in their state. They understand the legal requirements for Social Security cases and can represent you in formal hearings before an Administrative Law Judge. According to Social Security Administration data, approximately 75% of people who have representation at a hearing before a judge are represented by attorneys. Attorneys typically work on a contingency fee basis, meaning they only receive payment if you receive past-due benefits (called "backpay"). Federal law caps this fee at 25% of your backpay or $7,200, whichever is less.
Non-attorney representatives include authorized agents and accredited representatives. These individuals must pass Social Security's accreditation test, which covers Social Security law and procedures. Many non-attorney representatives work for nonprofits or disability advocacy organizations. They can represent you at all stages of the Social Security process, including hearings. Their fees are also regulated by federal law and typically charged as a percentage of backpay or a flat fee.
There are also organizations called "Work Incentive Planning and Assistance" (WIPA) projects and "Protection and Advocacy for Beneficiaries of Social Security" (PABSS) programs. These organizations provide free information and support to people with disabilities. They do not charge fees for their services because they receive federal funding for this work.
A guide to representation options will explain the differences between these types of representatives, what they can do, and how fees work. This information helps you understand what to look for if you decide you want someone to help you work with Social Security. The practical takeaway is understanding that representation comes in multiple forms, each with different levels of training and different fee structures, so you can make an informed choice about what approach fits your situation.
The Social Security disability process has several stages. Understanding what happens at each stage helps you know what to expect and what information may be important to have ready.

The initial application is the first stage. When you submit information to Social Security about your disability, they review your medical records, work history, and other information you provide. The Social Security Administration processes hundreds of thousands of initial applications each year. According to 2023 data, the approval rate at the initial application stage was approximately 32%. This means about two out of three people do not receive an approval at this first stage.
If your application is denied, you can request reconsideration. At this stage, a different reviewer looks at your case. The approval rate at reconsideration is even lower, at around 11%. This stage is also relatively quick, typically completed within a few months.
If reconsideration is denied, you can request a hearing before an Administrative Law Judge (ALJ). This is a more formal process where you can present evidence and testimony about your condition. A judge then makes a decision based on the evidence presented. The approval rate at the hearing stage is much higher—approximately 62% of cases that reach a hearing result in approval. This is one reason why having representation can be important; representation rates are higher at the hearing stage than at earlier stages.
If the judge denies your case, you can request Appeals Council review, and after that, you may be able to pursue judicial review in federal court. However, most cases are decided at the hearing stage.
A guide covering representation options typically walks through what information you need at each stage and what representatives do at each point in the process. Understanding these stages helps you see where professional guidance might be most valuable to you. The practical takeaway is recognizing that the disability process has multiple decision points, and the chances of approval increase significantly once cases reach a hearing with a judge.
Medical evidence is the foundation of any Social Security disability claim. Your medical records, test results, and doctor's statements form the basis of how Social Security evaluates your case. Representatives play an important role in making sure the right medical information is included.

Social Security looks for specific information in medical records. They want to see documentation of your diagnosis, how the condition affects your ability to function in daily activities, and what treatment you have received. Medical evidence might include hospital records, imaging studies, laboratory results, mental health evaluations, and detailed notes from your doctors. The strength and consistency of your medical evidence directly affects whether Social Security will find you disabled.
Many people find that gathering all their medical records is time-consuming. Records might be scattered across multiple doctors, hospitals, and clinics. Representatives often help by requesting records from all your medical providers and organizing them in a way that clearly shows your condition and its impact. This is called developing the record.
Representatives may also suggest that you see certain specialists if your records lack important information. For example, if you have arthritis but have never seen a rheumatologist, a representative might suggest this visit would help document your condition more thoroughly. Similarly, if you have mental health symptoms but have not been evaluated by a psychiatrist or psychologist, a representative might recommend this evaluation would strengthen your case.
Some representatives work with medical experts who can review your case and write reports explaining how your medical condition prevents you from working. These reports, called medical expert reports or treating physician statements, can be very persuasive in Social Security hearings.
An informational guide about representation options will explain how representatives gather and organize medical evidence and why strong documentation matters in disability cases. The practical takeaway is understanding that having organized, complete medical records and documentation of how your condition affects your functioning is essential, and representatives have experience in knowing what information Social Security needs and how to present it effectively.
When you decide you want representation, you have several options for finding qualified representatives. The Social Security Administration maintains lists of authorized representatives and accredited attorneys on their website. You can search by location and type of representative. The "Find Legal Representation" tool on the Social Security website provides names, contact information, and background information about representatives in your area.
