Disability paperwork can feel like a different language, especially when a letter is packed with acronyms. This Social Security disability glossary translates the SSA terms you’ll see in Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) claim forms and notices.
Each entry has two parts, a plain-English definition and a note on why the term matters in a disability claim.
AOD (Alleged Onset Date)
Definition: The date you say your disability began and you could no longer work in a sustained way.
Why it matters: The SSA and DDS compare this date to the evidence and may use it to set back pay and eligibility periods.
Definition: The judge who runs a disability hearing and issues a written decision after reviewing your case.
Why it matters: An ALJ decision gives you a chance to answer questions about your limits and your record.
Definition: The level of review after an ALJ decision where the Appeals Council may deny review, issue a decision, or send the case back to the ALJ.
Why it matters: This step focuses on whether the hearing decision followed the rules and used the evidence correctly.
Definition: Past-due benefits owed for eligible months before a decision is made, if the claim is approved.
Why it matters: The amount depends on dates in your file, including your disability onset and application date. For SSDI, the five-month waiting period and the 12-month retroactive limit from the application date affect how many months are paid.
Definition: The SSA’s Listing of Impairments, a set of medical criteria used to evaluate specific conditions.
Why it matters: You may see listing language in decisions because you can be approved by meeting or equaling a listing.
Definition: Monthly payments and related support that may be available through SSDI, SSI, or both, depending on eligibility.
Why it matters: The type of benefit you apply for affects what the SSA looks at first, such as work history for SSDI or financial limits for SSI.
Definition: A medical or psychological exam with a contracted provider scheduled by DDS reviewers that the SSA pays for.
Why it matters: A CE can fill gaps when records are missing or outdated. The report influences the medical decision.
Definition: A periodic review the SSA uses after approval to confirm you still meet disability rules.
Why it matters: Knowing a CDR exists reminds you to keep treatment records organized after benefits start.
Definition: The person who applied for SSDI or SSI and is asking the SSA to find them disabled under its rules.
Why it matters: Many letters use claimant instead of your name, so recognizing the term can reduce confusion.
Definition: A state agency that works with the SSA to gather medical evidence and make disability decisions at the initial and reconsideration levels.
Why it matters: DDS requests medical records, forms, and exams while developing your claim. Responding quickly helps avoid delays.
Definition: The last date a person meets insured status for SSDI based on work credits.
Why it matters: For SSDI, disability must be established on or before the DLI, so timing and records around that period matter.
Definition: A decision that the claim cannot be approved, which may be for medical reasons or for non-medical eligibility reasons.
Why it matters: The reason for denial affects what you can fix on appeal, such as adding medical evidence versus correcting eligibility details.
Definition: A person authorized to represent you in your disability claim, such as an attorney or qualified non-attorney representative.
Why it matters: A representative can help develop evidence, communicate with SSA, and handle parts of the claim process on your behalf.

Definition: Information SSA and DDS reviewers use to evaluate a claim, including medical records, testing, and statements about functioning.
Why it matters: Decisions are based on what is in the file, so missing records can leave important limitations undocumented.
Definition: A questionnaire asking about daily activities, symptoms, and how conditions affect tasks like walking, concentrating, and self-care.
Why it matters: The form helps document day-to-day limits in your own words, which can support the medical evidence.
Definition: A set of rules the SSA uses to combine factors like age, education, and work background with a residual functional capacity assessment.
Why it matters: The grid rules affect the outcome when your condition does not meet a listing but the evidence shows work limitations.

Why it matters: If insured status is not met, an SSDI claim will be denied even when the medical evidence is strong.

Why it matters: The initial notice starts the clock for appeal deadlines and explains the reason for the decision.
Definition: A Blue Book standard that a condition can meet exactly or equal in severity based on medical findings.
Why it matters: Listing language often appears in denial letters and understanding it helps you see what evidence the SSA needed.
Definition: A medical condition that must be established by objective medical evidence from an acceptable medical source, not by symptoms you report.
Why it matters: The SSA and DDS generally need an MDI before they can consider how symptoms affect functioning.
Definition: A clinician who may testify at a hearing to help the ALJ interpret medical evidence in the record.
Why it matters: ME testimony can shape how the judge views diagnoses, severity, and whether a listing is met or equaled.
Definition: The date disability is considered to have started for SSA purposes. It may be the date you allege or the date the SSA establishes from the evidence.
Why it matters: The onset date affects eligibility timing and how far back benefits can be paid if the claim is approved.
Definition: Benefit amounts the SSA determines you were not eligible to receive.
Why it matters: Overpayment notices come with repayment options and appeal rights, so the notice details are important.
Definition: Work done within the five years before becoming disabled that was substantial and lasted long enough for you to learn the job.
Why it matters: The SSA uses PRW to decide whether you can return to work you did in the past, based on your residual functioning capacity assessment.
Definition: A date the SSA uses as the application date when an earlier contact showed intent to file.
Why it matters: It allows the benefits start date to be earlier than when you complete the application.

Why it matters: SSDI eligibility depends on work history as well as medical rules, so work credits and DLI show up in letters.

Why it matters: Records from treating sources usually provide the most detailed picture of symptoms over time.

Why it matters: VE testimony can influence how the ALJ evaluates your past work and other work options.
