In California, Disability Determination Services is the state agency that decides the medical side of your Social Security disability claim. It sits inside the California Department of Social Services, is fully federally funded, and employs Disability Evaluation Analysts who work with licensed medical and psychological consultants to review your records. Whether you applied for Social Security Disability Insurance or Supplemental Security Income, this office makes the call on whether you qualify as disabled under federal rules, and about 62 percent of initial claims are denied at this stage.1Social Security Administration.

Who Reviews Your Claim and How It Gets to Them
When you file for disability, your local Social Security field office handles the non-medical pieces first: your age, work history, and Social Security coverage.2Social Security Administration. Disability Determination Process Once those are confirmed, the file is forwarded to California DDS for the medical determination. Every state has its own DDS, and California’s is one of the largest in the country.
Inside DDS, your file lands with a Disability Evaluation Analyst.3CalCareers. Disability Evaluation Analyst The analyst is not a physician. Their job is to pull your medical records, follow up with your treating providers, and build the evidence file. A licensed medical or psychological consultant then reviews that evidence with the analyst, and the two of them jointly decide your claim.
The medical standard is identical for SSDI and SSI. SSDI depends on whether you have earned enough work credits through payroll taxes; SSI is needs-based and limits countable resources to $2,000 for an individual or $3,000 for a couple.4Social Security Administration. Spotlight on Resources You can apply for both at once. Either way, DDS asks the same question: can you work?
The Five-Step Evaluation DDS Uses
California DDS does not make a holistic judgment call. It follows a sequential five-step process set by federal regulation, and your claim can end at any step.5Social Security Administration. Code of Federal Regulations 404.1520
Step 1 — Are you working? If your current earnings exceed the substantial gainful activity threshold, you are found not disabled and the analysis stops. In 2026, SGA is $1,690 per month for non-blind individuals and $2,830 per month for blind individuals.6Social Security Administration. Substantial Gainful Activity The figures are adjusted each year.
Step 2 — Is your impairment severe? Your condition must meaningfully limit basic work activities and must have lasted or be expected to last at least 12 months, or result in death. Minor conditions end the analysis here.
Step 3 — Does your condition meet a listed impairment? SSA maintains a catalog of conditions considered severe enough to automatically qualify. If your medical evidence meets a listing, you are approved without further analysis.
Step 4 — Can you do your past work? DDS builds a residual functional capacity profile and compares it against the demands of jobs you held in the past five years. If you can still perform any of that past work, your claim is denied.
Step 5 — Can you do any other work? If you cannot return to past work, DDS considers your age, education, and transferable skills to decide whether other jobs exist in the national economy that you could perform. The medical-vocational guidelines come into play here.7Social Security Administration. Medical-Vocational Guidelines
The burden of proof shifts at Step 5. Through the first four steps, you prove you are disabled. At Step 5, the agency must identify work you could do. If it cannot, you are found disabled. For older claimants with limited education and physically demanding work histories, the guidelines often direct a finding of disability at this step even when the medical evidence by itself might not seem overwhelming.
What Evidence DDS Actually Looks At
The quality of your paperwork drives how quickly and accurately DDS can decide. Two forms do most of the heavy work.
The Adult Disability Report (Form SSA-3368) lists every doctor, hospital, and clinic that has treated your condition. DDS uses it to request records, so accurate names, addresses, and phone numbers matter. Incomplete provider information creates delays while the analyst tracks down the right facility.8Social Security Administration. SSA-3368-BK Disability Report Adult You will also list every medication and any side effects that interfere with daily functioning.
The Function Report (Form SSA-3373-BK) asks you to describe a typical day from waking to bedtime, covering meal preparation, personal care, finances, and getting around.9Social Security Administration. SSA-3373-BK Function Report Adult People underestimate this form. DDS uses it to cross-check what your records say against how your condition plays out in daily life. If your records describe severe back pain but your Function Report has you shopping, cooking, and mowing the lawn without difficulty, that gap will hurt your claim.
Your work history matters at Steps 4 and 5. As of June 2024, SSA only considers work from the past five years, a change from the previous 15-year lookback.10Federal Register. Intermediate Improvement to the Disability Adjudication Process, Including How We Consider Past Work For each job in that window, DDS looks at the physical demands: how much you lifted, how long you stood or walked, whether the work was repetitive, and how much interaction with coworkers or the public it required.
How Medical Evidence Is Weighed
Once your file reaches the analyst, DDS pulls records from every source you listed. You will have signed an authorization that lets DDS request treatment notes, lab results, imaging, surgical reports, and discharge summaries. The analyst reviews everything looking for clinical findings that support or contradict the limitations you describe.
Evidence does not need to come from specialists. Primary care records, emergency room visits, and mental health treatment notes all count. What matters is objective content. A note saying “patient reports severe pain” carries less weight than one documenting “range of motion limited to 40 degrees with visible muscle spasm on examination.”
Consultative Examinations
If your records lack the detail needed for a decision, DDS can order a consultative examination at no cost to you. It is a one-time evaluation by a physician or psychologist, sometimes your own treating doctor and sometimes an independent provider chosen by DDS.11Social Security Administration. Code of Federal Regulations 404.1519 The exam is federally funded and designed to fill specific gaps, not to provide ongoing care.12Social Security Administration. Consultative Examination Guidelines
DDS schedules the appointment and sends you the date, time, and location. If you have to travel, you may be eligible for reimbursement under federal regulation.13Social Security Administration. Code of Federal Regulations 404.999b Skipping the exam without rescheduling almost always leads to a denial for insufficient evidence. The examiner’s report goes directly to the DDS analyst and becomes part of your permanent file.
The Blue Book and Residual Functional Capacity
At Step 3, DDS checks your condition against the SSA Listing of Impairments, commonly called the Blue Book. It covers 14 categories of adult conditions, from musculoskeletal and cardiovascular disorders to cancer, neurological conditions, mental disorders, and immune system disorders.14Social Security Administration. Listing of Impairments – Adult Listings Part A Each listing spells out specific medical criteria, not just a diagnosis.
A diagnosis alone does not qualify you. Having multiple sclerosis or lupus does not automatically mean approval. The evidence must satisfy every criterion in the relevant listing.15Social Security Administration. Code of Federal Regulations 404.1525 If your condition comes close but does not match perfectly, DDS can still find that it equals a listing in severity, meaning the combined effect of your impairments is medically equivalent to a listed condition. If it neither meets nor equals a listing, the analysis moves to Steps 4 and 5.
When no listing applies, DDS prepares a residual functional capacity assessment: a detailed profile of what you can still do. It covers physical abilities such as sitting, standing, walking, lifting, and carrying, along with mental abilities like concentrating, following instructions, and interacting with others.16Social Security Administration. Residual Functional Capacity The RFC sorts your physical capacity into exertional levels: sedentary, light, medium, heavy, or very heavy. The more restricted your RFC, the fewer jobs the agency can point to at Step 5. For older workers with limited education and no transferable skills, a sedentary RFC often leads to approval.
How Mental Health Claims Are Evaluated
Mental health claims run through the same five steps, but DDS adds a technique for rating severity. The analyst and psychological consultant score four functional areas: understanding, remembering, or applying information; interacting with others; concentrating, persisting, or maintaining pace; and adapting or managing yourself.17Social Security Administration. Code of Federal Regulations 404.1520a
Each area is scored on a five-point scale from “none” to “extreme.” Ratings of “none” or “mild” across the board usually mean the impairment is not severe, ending the review at Step 2. “Marked” or “extreme” in two or more areas tends to push the claim toward approval. “Moderate” ratings sit in the middle ground, and DDS has to look harder at how those limitations show up in actual work settings.
Records from a treating psychiatrist or psychologist carry real weight. Longitudinal treatment notes, showing how your condition shifts over months, give DDS a much clearer picture than a single evaluation. Consistent notes describing symptoms, medication responses, and functional limitations are what the agency needs to see.
Staying in Contact With Your Analyst
California DDS runs multiple offices to handle the state’s claim volume. After your application is forwarded from the field office, you will get correspondence identifying the DDS branch handling your case and the direct phone number of your assigned analyst.
Keeping in touch is one of the more useful things you can do. If you see a new specialist, undergo surgery, get new test results, or experience a significant change in your condition, let the analyst know. New evidence submitted before a decision is made gets folded into the review. Evidence that arrives after the decision requires an appeal, which is a much longer road. Keep copies of everything you send and note the date you sent it.
If Your Claim Is Denied
Most initial claims are denied. The national denial rate at the initial level runs about 62 percent, and climbs to roughly 84 percent at reconsideration.1Social Security Administration. Disability Determinations and Appeals Fiscal Year 2024 Many denials come from incomplete medical evidence rather than from claimants who are not actually disabled, which is why the appeals process matters.
The first appeal level is reconsideration. You have 60 days from the date you receive the denial notice to file Form SSA-561.18Social Security Administration. Request Reconsideration Missing the deadline generally means starting over, though SSA can grant an extension for good cause such as serious illness, a death in the family, or not receiving the notice.19Social Security Administration. Code of Federal Regulations 404.911 At reconsideration, a different DDS analyst and medical consultant review your entire file from scratch, including any new evidence you submit. This is your chance to fix the gaps that sank the initial claim.
If reconsideration upholds the denial, the next step is a hearing before an administrative law judge. The process leaves DDS at this point. You testify before a judge who can question you directly, review all the evidence, and call vocational or medical experts. Approval rates are significantly higher at the hearing level than at the initial or reconsideration stages.20Social Security Administration. Appeal a Decision We Made After a hearing denial, you can ask the Appeals Council to review whether the judge applied the law correctly, and after that, you can file suit in federal district court. Each level carries the same 60-day filing deadline. The full process from initial application through a hearing can take well over a year, so filing appeals promptly and submitting updated medical evidence at every stage is what keeps a claim moving.
