Disability Determination Services

Samandra Murphy, Director


Disability Determination Services (DDS) is an agency in the Mississippi Department of Rehabilitation Services (MDRS) which operates in a partnership with the Social Security Administration (SSA) to make disability decisions on Social Security and Supplemental Security Income disability claims.  This office handles claims from all 23 SSA offices in Mississippi.


About the Social Security Disability Program

  Applicants file for disability benefits through the Social Security Administration (SSA.) These claims are forwarded to DDS where criteria, set forth by SSA, is used in evaluating the claim for disability.

When a claim reaches DDS, it is assigned to a Disability Examiner (DE). Examiners are responsible for obtaining medical and vocational evidence to evaluate the claimant's allegations based on SSA criteria. If the medical records provided by the claimant's treating physician are incomplete, the DE may request a consultative examination (CE), at no cost to the claimant.

DDS has a Medical Unit staffed with medical and psychological consultants who provide expert opinions concerning the claimant's residual functional capacity. When all medical and vocational development is complete, a recommended decision is rendered to the Social Security Administration. All decisions are subject to review by either our Internal Quality Component (Quality Assurance) or SSA Office of Quality Performance. All decisions of DDS may be appealed by contacting the Social Security Administration.
