What is the primary concern in step five of the SSDI claims process?

In the Social Security Disability Insurance (SSDI) claims process, step five focuses on whether the claimant’s impairment precludes them from performing any type of work that exists in the national economy. This step is critical because it assesses the claimant's ability to adapt to any alternative type of employment, given their medical condition and residual functional capacity.

At this stage, if the Social Security Administration (SSA) determines that despite the impairments, the claimant can still perform other work available in significant numbers, the claim for disability benefits may be denied. The evaluation involves considering the claimant’s age, education, work experience, and residual functional capacity to ascertain their ability to secure gainful work. Therefore, identifying the inability to participate in any work becomes the focal point, as this directly influences the outcome of the claim.

The other options, while relevant to the broader context of the claims process, do not capture the essence of step five's main inquiry regarding work capacity. For example, evidence of substantial gainful activity assesses past employment but does not address current working capabilities. Access to rehabilitation services relates to support rather than direct work ability, and applying for alternative benefits does not tie directly to the threshold determination of overall work capability in step five.
