The Social Security Administration (SSA) pays two types of disability benefits to people who can no longer work due to illness or injury.
The first is SSDI (Social Security Disability Insurance), which works like insurance: it is financed by taxes the person paid while working, and is collected when disability arrives.
The second is SSI (Supplemental Security Income), a payment for people with disabilities, blind people, or those over 65 years old who have very low income and resources, whether they have worked or not.
Both programs exist for the same purpose: so that a person who loses the ability to earn a living has a monthly income and access to medical care. This guide explains what illnesses qualify, what documentation the SSA requests, and how to file an application, with attention to what changes in California, Georgia, Illinois, New York, New Jersey, and Pennsylvania, where Conexión Legal serves the Hispanic community.
Overview of disability benefits and insurance benefits
SSDI pays a monthly amount calculated based on the person's income history. In 2026 the average payment is around $1,600, and the maximum exceeds $4,000. It also covers certain family members, such as minor children and spouses.
SSI pays a fixed federal amount, which in 2026 is $994 per month for a single person. California, New York, New Jersey, and Pennsylvania add a state supplement to that amount. Georgia and Illinois, with few exceptions, pay only the federal amount.
Both benefits are adjusted each January with COLA (cost of living adjustment), which follows inflation from the previous year. The 2026 adjustment was 2.8%.
There is an important practical difference for the immigrant community: SSDI requires having contributed with a valid Social Security number to work, and SSI is reserved for citizens and certain categories of legal residents. A lawyer can review in a few minutes whether the person's history meets those requirements before starting the process.
Eligibility requirements for Social Security disability
The Social Security definition of disability is strict. The person must have a medical condition that prevents them from performing any substantial work, and that condition must have lasted or be expected to last at least 12 months, or result in death. The SSA measures "substantial work" with a figure: in 2026, earning more than $1,690 per month ($2,830 for blind people) disqualifies the application, regardless of diagnosis.
For SSDI, work credits are also required. One credit is earned for approximately every $1,890 in earnings, with a maximum of four per year. A person aged 50 generally needs 28 credits, and 20 of them must have been earned in the last 10 years. Younger workers need fewer.
The SSA has a fast track for terminal cases, called TERI. When the file indicates a disease that is likely to cause death, the agency flags it and processes it in weeks instead of months. The patient or their family can request that designation when filing the application.
How to prepare medical documentation to receive benefits
The SSA decides based on paperwork. The examiner rarely sees the applicant, so the medical file must tell the entire story by itself.
First, gather records from all doctors, hospitals, and clinics that have treated the condition, with dates, diagnoses, treatments, and response to each treatment. Second, ask each specialist for a written report that describes the illness, the prognosis, and most importantly, the specific work limitations: how much weight the person can lift, how long they can stand or sit, whether they can concentrate during a full workday.
Third, include results of recent diagnostic tests, because a study from three years ago carries little weight against one from three months ago.
Process to apply for Social Security disability (SSA)
The application is filed online at ssa.gov/es, by phone at 1-800-772-1213 (with Spanish option) or in person at a local office. The Los Angeles, Fresno, Chicago, Atlanta, and New York offices operate by appointment only, and it is advisable to schedule several weeks in advance.
SSDI has a five-month waiting period: payments begin to accrue from the sixth month of disability, even if the application is approved later. The only exception is amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease), which since 2020 begins payment from the first month.
About two out of three initial applications are denied. When that happens, the person has 60 days to request reconsideration, and if also denied, another 60 days to request a hearing before an administrative law judge.
At the hearing the odds change significantly, especially with legal representation: disability lawyers are paid only if the case is won, with a cap set by the SSA of 25% of back payments up to a maximum of $9,200.
Illnesses that qualify for disability benefits: overview
The SSA publishes the Blue Book, a list of conditions organized into 14 categories for adults and as many for children. Each entry describes what medical tests and what degree of limitation are needed to qualify automatically. If a person's illness appears in the list and meets the criteria, the application is approved without further analysis.
When the illness is not in the list, or is but does not meet the exact criteria, the SSA applies medical equivalence: it evaluates whether the person's combination of conditions is equivalent in severity to any entry in the Blue Book. Many cases are won this way, and this is where a good medical file makes the difference.
There is also the Compassionate Allowance (CAL) initiative, a list of more than 280 diseases so serious that the SSA approves them with minimal documentation, often in less than a month. It includes ALS, many types of advanced cancer, degenerative neurological diseases, and several rare childhood conditions.
Kidney disease: criteria and documentation
Chronic kidney disease appears in section 6 of the Blue Book. It automatically qualifies a person on chronic dialysis (hemodialysis or peritoneal dialysis) expected to last at least 12 months, one who received a kidney transplant (during the 12 months following surgery), and one with advanced kidney disease with documented complications, such as severe anemia, neuropathy, or significant weight loss.
The file must include records from each dialysis session, nephrology reports, and kidney function tests (creatinine, glomerular filtration rate, albumin) from at least the last three months.
End-stage kidney disease has an additional advantage: it provides access to Medicare without waiting the usual 24 months of SSDI, and regardless of the person's age. Many families in Fresno or Kane County, where access to nephrologists is more limited, discover this benefit late. It is best to request it from day one.
Heart failure and other heart diseases
Section 4 of the Blue Book covers cardiovascular diseases. For chronic heart failure, the SSA requires an echocardiogram showing an ejection fraction of 30% or less, or a dilated left ventricle, along with symptoms that seriously limit daily activity or a stress test that the person cannot complete at a low level of exertion.
There are also entries for coronary artery disease, recurrent arrhythmias with syncope, peripheral arterial disease, and congenital heart disease.
What carries the most weight in these cases is the description of physical limitations: if the person gets winded climbing one flight of stairs, if they need to rest after walking a block, if they have leg swelling by end of day. The cardiologist's report must translate the echocardiogram numbers into those concrete limitations.
Mental health: disorders that may qualify
Section 12 of the Blue Book covers mental disorders, and it is one of the categories with the most applications and most denials. Those that qualify most frequently are major depression and bipolar disorder, anxiety disorders and obsessive-compulsive disorder, schizophrenia and other psychotic disorders, post-traumatic stress disorder, neurocognitive disorders (including early-onset dementia), and intellectual disability.
In all of them the SSA requests two things: a diagnosis documented by a psychiatrist or psychologist, and evidence that the disorder severely limits one function (or markedly limits two) among these four: understanding and applying information, interacting with others, concentrating and maintaining pace, and adapting and managing oneself.
The file must include psychiatric evaluations, therapy notes, and hospitalization records. When standardized psychological tests exist, such as the WAIS for intellectual ability or the MMPI, they help greatly.
And one detail many applicants overlook: attempts to return to work that failed due to illness are evidence in favor, as long as they lasted less than six months. It is best to document them with dates and reason for departure.
Rheumatoid arthritis and musculoskeletal conditions
Rheumatoid arthritis is evaluated in section 14 (immune disorders) and injuries and diseases of the spine and joints in section 1.
For arthritis, the SSA looks for persistent inflammation or deformity in joints that prevents walking without aid or using hands for fine tasks, or involvement of other organs with constitutional symptoms such as fever, fatigue, and weight loss.
For the spine, the listing requires evidence of nerve root compression, spinal stenosis, or arachnoiditis, with imaging studies confirming it and with documented limitation for walking, standing, or using the arms.
X-rays, MRIs, and laboratory results (rheumatoid factor, anti-CCP, inflammation markers) are the foundation of the case. On top of that, the rheumatologist's or orthopedist's report must describe what treatments were tried, how the person responded, and what the prognosis is. These cases are won when the file precisely explains how much the person can lift, walk, or remain seated during a normal workday.
Bone marrow and hematologic diseases
Section 7 of the Blue Book covers blood and bone marrow disorders: hemolytic anemias such as sickle cell disease, coagulation disorders, bone marrow failure (aplastic anemia, myelodysplastic syndromes), and cases treated with bone marrow or stem cell transplant, which automatically qualify for the 12 months following transplant. Blood cancers, such as leukemias, lymphomas, and multiple myeloma, are evaluated in section 13 and many are on the Compassionate Allowance list.
The file needs reports from the hematologist, bone marrow biopsy results, and serial blood counts showing progression. As in the other categories, the functional impact must be documented: frequent transfusions, repeated infections, hospitalizations, fatigue that prevents a workday.
Insurance benefits and coordination with Medicare and other programs
Anyone receiving SSDI automatically obtains Medicare after 24 months of payments, regardless of age. The exceptions are ALS and end-stage kidney disease, which obtain it sooner.
Anyone receiving SSI obtains Medicaid, though the process varies by state. In California (Medi-Cal), Georgia, New York, New Jersey, and Pennsylvania, SSI approval activates Medicaid without a separate application. Illinois requires a separate application with the state.
A person can receive SSDI and SSI at the same time when their SSDI is low, and in that case SSI makes up the difference to the federal amount. Additionally, each state has supplementary programs: utility assistance, transportation for people with disabilities, property tax exemptions, and in California and New York, state short-term disability programs that can cover SSDI waiting months.
How to receive benefits and payment management
The first step after approval is to create an account at my Social Security (ssa.gov/myaccount), which allows you to view benefit status, download verification letters, and update information. The second is to activate direct deposit, because as of September 2025 the federal government stopped issuing paper checks except in rare cases.
SSDI payments arrive on Wednesdays, based on the beneficiary's birth date: second Wednesday for those born the 1st to 10th, third for those born the 11th to 20th, and fourth for the rest. SSI is paid on the 1st of each month. The annual calendar is published on the SSA website and it is advisable to review it, because when the date falls on a weekend or holiday the payment is advanced.
What to do if your disability benefits application is denied
The denial letter explains the reason, and that reason defines the strategy. The most common reasons are lack of medical evidence, income above the limit, disability expected to last less than 12 months, or the SSA concluded the person can do another type of work.
The appeal must be filed within 60 days from the date of the letter. Missing that deadline forces you to start over, with a new application and a new benefit start date.
This is when legal representation changes the outcome. A disability lawyer reviews the file, requests missing reports, prepares the applicant for the hearing, and questions the vocational expert the SSA brings to the room.
Conexión Legal connects the Hispanic community with lawyers who handle these cases in Spanish in California, Georgia, Illinois, New York, New Jersey, and Pennsylvania. The initial evaluation is free and can be requested 24 hours a day by phone or email.
Official Social Security (SSA) resources in the United States
The official Spanish-language site is ssa.gov/es, with online application, the Blue Book, payment calendar, and office locator. The national phone number is 1-800-772-1213, Monday to Friday from 8 a.m. to 7 p.m., with Spanish language option. People with hearing difficulties can call TTY 1-800-325-0778.
To find out what other federal or state programs might apply, the benefits finder at USA.gov (usa.gov/es/buscador-de-beneficios) asks basic questions and returns a personalized list.
Conclusion and next steps
If you or someone in your family has an illness that prevents you from working, these are the immediate actions: check if the condition appears in the Blue Book or on the Compassionate Allowance list, gather medical records from all providers and ask each specialist for a report with specific limitations, and file the application as soon as possible, because the application date determines when back benefits begin to be paid.
As the case progresses, continue attending medical appointments and keep every report. A file with gaps of months without treatment is the signal the SSA most uses to deny. And at the first denial letter, it is best to talk to a lawyer before the 60 days run out: most cases that are won are won at the hearing, with a complete file and someone who knows how to defend it.
