Disability Determination Services

Six DDS employees stand in front of the DDS, Oklahoma Seal and SSA Seal. With 'How can we serve you?

The Disability Determination Services makes medical eligibility determination on applications for Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) for the Social Security Administration (SSA).

These determinations are based on federal rules and regulations. All applications for benefits must be submitted through the SSA office.

SSDI pays disability benefits to individuals who are insured due to contributions to the Social Security trust fund through Social Security tax on their earnings. SSDI also makes payments to certain people with disabilities who are dependents of insured individuals.

SSI provides for payments to persons, including children under the age of 18, who have disabilities and limited income and resources.

The SSA, which makes decisions about eligibility for disability benefits, defines disability as the inability to engage in substantial gainful activity because of any medically determinable physical or mental impairment which has lasted or is expected to last at least 12 months or is expected to result in death. Disability Determination Services operations are fully funded by the SSA.

DRS and Disability Determination

Social Security Disability Benefits: An Overview

The Social Security Administration pays disability benefits under two programs:

Social Security Disability Insurance (SSDI)
SSDI provides disability benefits to blind or disabled individuals who are insured based on federal insurance contributions (FICA) paid into the Social Security Trust Fund. Certain family members can also receive benefits based on a worker's contributions.
Supplemental Security Income (SSI)
SSI provides benefits to individuals who are disabled, blind or elderly, with limited income and resources, including children under age 18, who are disabled, blind or elderly.

The medical requirements that determine who is eligible for disability payments are the same under both programs. Under the Social Security system, disability payments are based on inability to work. Individuals are considered "disabled" if they are unable to do any kind of work and their disabilities are expected to last for at least twelve months or result in death.

Application Process

Are you eligible to apply for benefits?

Your local Social Security office staff will review the non-medical portion of your application to see if you are eligible to apply for disability benefits. They will look at your work history to determine whether you have worked long enough and recently enough, your age, your income and your resources.

In Oklahoma, your application is then sent to the Disability Determination Services (DDS).  The DDS, a division of the Oklahoma Department of Rehabilitation Services, is responsible for making timely, and accurate disability determinations in accordance with Social Security Rules and Regulations.

DDD personnel, consisting of a physician or psychologist and a disability adjudication specialist, will consider all the facts in your case using medical information from your doctors, hospitals, clinics, and other places where you have been treated.

Once a determination on your claim is reached, you will get a written notice from the Social Security Administration explaining the determination. If your claim is approved, the notice will show the amount of your benefit and when payments will start.
