The benefits you earned.
The advocates you deserve.

Social Security Disability Insurance (SSDI) is an earned benefit for people who have worked and paid Social Security taxes long enough to be insured, and the payment amount is based on your earnings record. Supplemental Security Income (SSI) is a needs-based program for people with limited income and resources, and it requires no work history at all. Both programs use the same medical definition of disability, and some people qualify for both at once, which is called a concurrent claim. SSDI comes with Medicare after a waiting period, while SSI usually brings Medicaid right away in most states.

Disability representation works on a contingent-fee basis: you pay no fee unless you win benefits. Fees are federally capped by law at 25 percent of your back pay, up to a dollar maximum set by SSA, which was raised to $9,200 in late 2024 and is now adjusted annually. SSA must approve the fee, and it is usually withheld from your past-due benefits and paid directly to the representative, so nothing comes out of your ongoing monthly checks. Out-of-pocket case costs, such as charges for copies of medical records, may apply separately, and your fee agreement will spell those out.

The initial decision typically takes several months, and many claims take longer when records are slow to arrive or a consultative exam is needed. If you are denied and appeal, reconsideration commonly adds several more months, and waiting for a hearing before an Administrative Law Judge often takes a year or more depending on the hearing office. From first application to a hearing decision, many claimants wait one to two years or longer. Claims involving terminal illness or Compassionate Allowances conditions can be approved much faster, sometimes in weeks, and approved claimants receive back pay for the waiting time.

No condition is automatic, because every claim must also meet non-medical rules and be supported by medical evidence, but some conditions are treated as clearly disabling. SSA's Compassionate Allowances list, which includes more than 280 conditions such as ALS, pancreatic cancer, and acute leukemia, fast-tracks approval in a matter of weeks. Beyond that list, the Blue Book Listing of Impairments describes the specific clinical findings that make conditions like heart failure, COPD, epilepsy, or schizophrenia qualify at step three. Most people are approved not by meeting a listing but by showing their remaining capacity rules out full-time work.

You can work while applying, but your earnings must stay below the substantial gainful activity (SGA) level, which is $1,690 per month for non-blind individuals in 2026 and adjusted annually. Earning above that amount will generally cause a denial at step one regardless of how serious your medical condition is. Even part-time work below the limit can be used to question your credibility, so it should be documented and explained carefully. Short work attempts that failed because of your condition, called unsuccessful work attempts, usually do not count against you.

SSDI is based on your lifetime earnings record, not on the severity of your condition, so amounts vary widely; in 2026 the average SSDI payment is roughly $1,600 per month, with a maximum above $4,000 for high earners, and figures are adjusted annually. SSI pays up to the federal benefit rate of $994 per month for an individual in 2026, adjusted annually, minus your countable income, and some states add a supplement. Approved claimants also typically receive a lump sum of back pay covering the months they waited. You can see your own SSDI estimate by checking your Social Security Statement at ssa.gov.

Most initial applications are denied, and the majority of denials come down to evidence rather than the underlying condition. Common reasons include insufficient medical records or treatment gaps, earnings above the substantial gainful activity limit, missing a consultative exam, failure to return forms, not meeting the duration requirement of 12 months, or a finding that you can still do past or other work. Technical denials also happen when SSDI work credits are lacking or SSI income and resource limits are exceeded. A denial is not the end: many claims that lose on paper are approved at the hearing level, so appealing within 60 days is almost always the right move.

You are not required to have a representative, but the hearing is a legal proceeding with medical opinion rules, vocational testimony, and strict evidence deadlines, and government data has long shown that represented claimants are approved at meaningfully higher rates. A representative can obtain and organize your medical records, secure detailed opinions from your doctors, prepare you to testify, and cross-examine the vocational witness whose testimony often decides the case. Because fees are contingent, federally capped, and paid only out of back pay if you win, there is little financial downside to getting help before your hearing.
