Disability Determination Services (DDS) are state agencies fully funded by the federal government. The DDS office receives Social Security Disability applications from the Social Security Administration field offices after the field office has verified the non-medical eligibility for each disability claimant. The Disability Determination Services office obtains medical evidence for each Social Security Disability claim, reviews the evidence and makes an initial disability determination according to Social Security Disability law. If the DDS does not have enough information to determine a claimant's disability status, they will request a consultative examination for the claimant. After the DDS examiner has received the disability report from the Consultative Examiner they will make their disability decision. After the Social Security Disability decision is made the disability case is sent back to the Social Security Administration field office where a letter of denial or acceptance is sent to the disability claimant. The Disability Determination Services office may also make subsequent disability determinations for previous Social Security Disability Insurance or Supplemental Security Income cases if the claimant makes subsequent appeals.
