To file for disability in Colorado, you apply through the federal Social Security Administration rather than any state agency. You can submit an SSDI application online at ssa.gov, call 1-800-772-1213 to start an SSI claim by phone, or visit a local Social Security field office. Once filed, your claim moves to Colorado’s Disability Determination Services office in Aurora, which decides the medical side of your case. Initial decisions take roughly six to eight months, and most are denied the first time, so preparation and persistence matter more than speed.
Decide Which Program You’re Applying For
The SSA runs two separate disability programs, and which one fits you changes the forms, the eligibility test, and sometimes the waiting period.
Social Security Disability Insurance (SSDI) is an insurance program funded by payroll taxes. You qualify based on your work history and past Social Security contributions, and your monthly benefit reflects your past earnings. The general rule for workers 31 and older is 40 work credits, with at least 20 earned in the 10 years before the disability began.1Social Security Administration. Disability Benefits – How Does Someone Become Eligible Younger workers can qualify with fewer.
Supplemental Security Income (SSI) is needs-based. There’s no work history requirement, but your countable resources can’t exceed $2,000 as an individual or $3,000 as a couple, and your income must fall below program limits.2Social Security Administration. Spotlight on Resources Your home, one vehicle, and certain personal items generally don’t count against the resource limit.
Both programs use the same medical definition: a physical or mental condition expected to last at least 12 months or result in death, severe enough to prevent you from working.3Social Security Administration. 20 CFR 404.1505 – Basic Definition of Disability Both also use the substantial gainful activity threshold: if you’re earning more than $1,690 per month in 2026 ($2,830 if you’re blind), the SSA will find you able to work regardless of your diagnosis.4Social Security Administration. Substantial Gainful Activity
Some people qualify for both. If your SSDI payment is low because of limited past earnings, SSI can bring your total benefit up to the SSI level. If that might be you, apply for both at once.
Gather Your Documents Before You Start
The single most useful thing you can do before filling out any form is pull your records together. Thin medical evidence is the most common reason claims are denied early.
Collect your Social Security number, birth certificate, bank information for direct deposit, and any marriage or divorce records. For the medical side, write down the name, address, and phone number of every doctor, hospital, and clinic that has treated your condition, along with treatment dates and a list of current medications with dosages. Request your actual medical records now, because providers often take weeks to respond and any lag pushes your whole timeline back.
You’ll also need job titles, duties, and dates for the five years before you stopped working. The SSA collects this on Form SSA-3368-BK, the Adult Disability Report, which asks about your conditions and how they limit what you can do.5Social Security Administration. SSA-3368-BK – Disability Report – Adult SSDI applicants also complete Form SSA-16-BK.6Social Security Administration. Application for Disability Insurance Benefits If you’re applying for SSI, be ready with detailed income, bank balance, investment, and asset records; eligibility hinges on those numbers.
How to Submit Your Application
SSDI applications can be completed entirely online at ssa.gov. The application lets you save your progress and come back later, and you receive electronic confirmation when you submit. For most people this is the fastest route.
SSI applications have historically required a phone or in-person interview. The SSA has started rolling out a simplified online SSI application for certain adults between 18 and 64 who are applying for both SSI and SSDI at the same time, but eligibility for the online version is limited.7Social Security Administration. Simplified Online SSI Application Now Available If the online SSI option isn’t open to you, call 1-800-772-1213 to schedule an appointment, or find your nearest Colorado field office through ssa.gov/locator.
Check every field before you submit. A wrong date, a transposed Social Security number, or a missing provider phone number creates processing delays on a timeline that is already long.
What Happens After You File
Your local SSA field office first checks the non-medical requirements: work credits if you’re applying for SSDI, income and assets if you’re applying for SSI. If you clear that screen, your file moves to Colorado’s Disability Determination Services office in Aurora, a division of the Colorado Department of Human Services.8Colorado Department of Human Services. Disability Determination Services Colorado DDS handles roughly 40,000 disability claims a year. Examiners and medical consultants there pull evidence from your providers and decide whether your condition meets the SSA’s standard.
If your records don’t give DDS enough to decide, they’ll schedule a consultative examination with an independent doctor. DDS pays for the exam.9Social Security Administration. Consultative Examination Guidelines Do not skip it. A missed consultative exam is treated as a failure to cooperate and almost always ends in a denial.
Initial decisions generally take six to eight months, and complex cases or slow medical records can stretch that further.10Social Security Administration. How Long Does It Take to Get a Decision After I Apply for Disability Benefits You’ll get the decision by mail. Certain severe conditions, primarily specific cancers, neurological disorders, and rare childhood diseases, qualify for Compassionate Allowances and move much faster.11Social Security Administration.

If You’re Approved
SSDI approval carries a mandatory five-month waiting period. Your first payment arrives in the sixth full month after the date the SSA determines your disability began, not the date you applied.12Social Security Administration. Is There a Waiting Period for SSDI Benefits ALS is the one exception; there’s no waiting period. Because most claims take months to process, you’ll likely receive back pay for the stretch between your sixth month of disability and your approval. The SSA may also pay up to 12 months of retroactive benefits for time before you filed, if your disability began earlier.
SSI has no waiting period. The 2026 federal SSI payment is $994 per month for an eligible individual and $1,491 for a couple.13Social Security Administration. SSI Federal Payment Amounts for 2026 Any income you receive reduces that payment, so your actual check may be smaller. Colorado also runs the Aid to the Needy Disabled-Colorado Supplement program, which pays additional amounts to certain SSI recipients between ages 0 and 59 who don’t receive the full federal benefit.14Colorado Department of Human Services.

If You’re Denied
Expect a denial on the first try. In recent years, about 63% of claims have been denied at the initial level and roughly 87% at reconsideration.15Social Security Administration. Outcomes of Applications for Disability Benefits Many people who are eventually approved had to appeal at least once. Every stage has a strict 60-day filing deadline, measured from the date you receive the denial letter. The SSA assumes you received it five days after the date on the letter.
There are four levels of appeal.
- Reconsideration. A different DDS examiner reviews your file from scratch. You can and should submit new medical evidence here, since thin documentation is the leading cause of denial. File within 60 days of the initial denial.16Social Security Administration. Understanding Supplemental Security Income Appeals Process
- Hearing before an Administrative Law Judge. Request this using Form HA-501 within 60 days of the reconsideration denial. You appear, often by video, before a judge who questions you directly, reviews your evidence, and may call medical or vocational experts. This is where the odds improve meaningfully, and where most applicants bring in a representative.17Social Security Administration. Request Hearing With a Judge
- Appeals Council review. You have 60 days after the judge’s decision to ask the Council to review it. The Council can deny review, decide the case itself, or send it back for another hearing.18Social Security Administration. Appeals Council Review Process
- Federal court. As a last resort, you can file a civil suit in federal district court. This involves court filing fees and typically requires an attorney.
Miss a 60-day deadline and your appeal effectively ends unless you can show good cause. If that happens, you’d need to start the whole application over.
When to Bring In a Representative
You can hire an attorney or accredited representative at any stage, but most people bring one in after the initial denial, often right before the ALJ hearing. Disability representatives generally work on contingency, so they’re paid only if you win.
Under a standard fee agreement, the representative’s fee is capped at 25% of your back pay or $9,200, whichever is less.19Social Security Administration. Fee Agreements – Representing SSA Claimants The SSA withholds that amount directly from your back pay and pays the representative, so nothing comes out of your pocket upfront. Some representatives use a fee petition rather than an agreement, which a judge approves and can sometimes exceed the $9,200 cap. Costs like obtaining medical records are usually billed separately and aren’t covered by the fee agreement.
A good representative handles paperwork, chases down additional medical evidence, prepares you for the hearing, and cross-examines vocational experts. At the ALJ level, where the case is genuinely decided on what gets presented in the room, that preparation does the most work.
