If you've applied for Social Security Disability Insurance (SSDI) in Texas, your application doesn't stay at the Social Security Administration (SSA) office where you filed it. It gets routed to a state agency called Texas Disability Determination Services (DDS). Understanding what that agency does — and how it fits into the broader SSDI process — helps you make sense of what's happening to your claim and why it takes as long as it does.
Texas DDS is a state agency that works under a partnership agreement with the federal SSA. When a Texas resident files for SSDI (or SSI), the SSA handles the non-medical side of the application — verifying your work history, calculating potential benefit amounts, and confirming basic program eligibility. The medical determination — the central question of whether your condition is disabling under SSA rules — gets handed off to Texas DDS.
DDS employs a team of disability examiners who work alongside medical and psychological consultants. Together, they review your medical records, evaluate how your impairments affect your ability to work, and issue an initial decision to approve or deny your claim.
Texas DDS operates out of offices in Austin and handles an enormous volume of cases each year for one of the most populous states in the country.
The full SSDI process moves through several stages, and Texas DDS is involved at the front end:
| Stage | Who Handles It | What Happens |
|---|---|---|
| Initial Application | SSA + Texas DDS | SSA verifies work credits; DDS reviews medical evidence |
| Reconsideration | Texas DDS | A different DDS examiner reviews the denied claim |
| ALJ Hearing | SSA (Office of Hearings Operations) | An Administrative Law Judge holds an independent hearing |
| Appeals Council | SSA Appeals Council | Reviews ALJ decisions for legal or procedural errors |
| Federal Court | U.S. District Court | Last-resort appeal outside the SSA system |
Texas DDS only handles the initial application and the reconsideration stage. Once a claim reaches the ALJ hearing level, it moves entirely into SSA's administrative court system.
Texas DDS examiners don't make decisions based on your word alone. They look at a specific set of factors defined by SSA rules:
Medical evidence is the foundation. DDS will request records from your treating physicians, hospitals, clinics, and any specialists you've seen. If records are missing or insufficient, DDS may schedule a Consultative Examination (CE) — a one-time appointment with an independent physician or psychologist paid for by SSA — to gather additional information.
Residual Functional Capacity (RFC) is the core medical-legal concept DDS applies. Your RFC represents what you can still do despite your impairments — how long you can sit, stand, lift, concentrate, or follow instructions. The RFC finding is then compared against your past work and, depending on your age, education, and work history, against other jobs that exist in the national economy.
The five-step sequential evaluation guides every DDS decision:
If you pass all five steps in your favor, DDS approves the claim. If you don't, it gets denied.
Texas, like most states, denies the majority of initial SSDI applications. Nationally, initial approval rates typically fall in the 20–35% range, though this varies by year, condition, and individual circumstances. Reconsideration approval rates are generally even lower.
This pattern is why the ALJ hearing stage — which is outside DDS's hands — tends to produce higher approval rates for claimants who persist through the process. The hearing gives you a direct opportunity to testify, submit additional evidence, and have an independent judge evaluate your claim.
Several variables shape what a DDS examiner sees and how they evaluate it:
Texas DDS follows the same federal rules as every other state's DDS agency — the same five-step process, the same RFC framework, the same Listings. But outcomes vary significantly from one claimant to the next, not because the rules change, but because the underlying facts do.
Two people with the same diagnosis can receive opposite decisions based on the depth of their medical records, their work history, their age, and how their condition is documented. The process is standardized. The inputs are entirely personal.
What Texas DDS will find when they open your file depends entirely on what's in it.
