What is the SSDI filing process in California?

Updated 09/02/2025


Applying for Social Security Disability Insurance (SSDI) in California is a multi-step process that requires careful preparation and persistence. While the Social Security Administration (SSA) oversees the program nationwide, the review of medical evidence in California is handled by the state’s Disability Determination Services (DDS). Understanding how the process works can help you avoid mistakes and strengthen your claim.

Please answer a few questions to help us determine your eligibility.


Understanding SSDI in California

SSDI provides monthly benefits to individuals who can no longer work due to a severe medical condition. To qualify, applicants must:


  • Have a disability that is expected to last at least 12 months or result in death.
  • Show they cannot engage in substantial gainful activity (SGA).
  • Have earned enough work credits through past employment and Social Security contributions.


Step 1: Confirm Eligibility

Before filing, applicants should review two main factors:


  • Work History – Most workers need 20 credits earned in the past 10 years before becoming disabled. Younger workers may qualify with fewer credits.
  • Medical Criteria – The SSA maintains a list of qualifying impairments in the “Blue Book.” Even conditions not listed may qualify if they prevent you from working.


Step 2: Gather Essential Documentation

A strong SSDI application relies on complete and accurate records, including:


  • Medical evidence: hospital records, diagnostic tests, prescriptions, and doctor statements.
  • Work records: job history, wages, and proof of how disability affects your ability to work.
  • Personal details: Social Security number, date of birth, dependents, and bank information for direct deposit.


Incomplete documentation is one of the most common reasons for initial claim denials.


Step 3: File the SSDI Application

You can submit your SSDI claim in California through three methods:


  • Online at the SSA website.
  • By phone with the Social Security Administration.
  • In person at a local SSA office in California.


Applicants must complete multiple forms, including the Disability Report and Work History Report, which detail medical conditions and their impact on daily life.


Step 4: Review by California Disability Determination Services (DDS)

After submission, the claim is forwarded to California DDS, where specialists and medical consultants evaluate:


  • Whether your condition meets SSA disability standards.
  • The severity of your medical limitations.
  • Whether you can perform past work or adjust to other types of work.


DDS may request additional documentation or schedule a consultative exam with an independent doctor.


Step 5: Decision and Timeline
  • Initial Decision – Most applicants receive a decision within 3–6 months.
  • Approval – If approved, benefits typically start after a five-month waiting period from the onset of disability.
  • Denial – If denied, applicants can file for reconsideration and continue the appeals process.


Appealing an SSDI Denial in California

Most SSDI claims are denied at first, but applicants have the right to appeal:


  1. Reconsideration – A new reviewer at DDS re-examines the case.
  2. Hearing with an Administrative Law Judge (ALJ) – You can present evidence and testimony.
  3. Appeals Council Review – Reviews errors made by the ALJ.
  4. Federal Court Review – Final legal option for challenging a denial.


Appeals can take months to years, but many claims are approved at the hearing stage.
