SSA Says I Can Perform My Past Work

Step 4: Where Past Work Claims Are Decided

If SSA has found your condition severe (Step 2) and it doesn't automatically qualify under the Listings (Step 3), the evaluation moves to Step 4. Here, SSA compares your current functional abilities — your Residual Functional Capacity (RFC) — against the demands of your past relevant work (PRW).

If SSA concludes that your RFC allows you to perform your past work, they deny your claim at Step 4 without ever reaching Step 5 (other work in the economy). This is a significant finding that shuts down many otherwise valid disability claims.

What Is "Past Relevant Work"?

SSA defines past relevant work (PRW) as work you performed in the last 15 years that:

• Lasted long enough for you to learn it
• Was done at the Substantial Gainful Activity (SGA) level (i.e., you were actually earning meaningful income from it)

Work done more than 15 years ago is generally not considered past relevant work. Short-term trial jobs or jobs performed below SGA level may also be excluded.

How SSA Evaluates Whether You Can Do Past Work

SSA evaluates your past work two ways:

1. As you actually performed it: What were the specific physical and mental demands of the job as you did it — the actual hours, lifting, walking, mental demands, etc.?
2. As generally performed: What does the Dictionary of Occupational Titles (DOT) say about the general requirements of that type of job in the national economy?

If you can't do the job as you performed it (perhaps because it required more lifting than the DOT average), SSA may still deny you if they find you could do the job as it's "generally performed."

Challenging the RFC Assessment

The foundation of any Step 4 challenge is often the RFC — SSA's assessment of your functional limitations. If SSA gave you an RFC of "medium work" but your treating physician's evaluation shows you can only do "sedentary work," the Step 4 comparison is based on faulty premises.

Improving your RFC documentation means:

• Getting a detailed RFC form or Medical Source Statement completed by your treating physician
• Documenting specific physical limitations: sitting time, standing time, lifting capacity, need for positional changes, need for breaks
• Documenting mental limitations: ability to concentrate, maintain pace, follow complex instructions, interact appropriately with supervisors and coworkers
• Documenting the effect of pain, fatigue, and medication side effects on functional capacity

When your physician's RFC assessment significantly restricts you compared to what SSA assumed, it can eliminate Step 4 as a basis for denial entirely.

Challenging How SSA Characterized Your Past Job

SSA relies heavily on the Dictionary of Occupational Titles (DOT) to define what your past job requires. But the DOT was last comprehensively updated in 1991 and doesn't always reflect how jobs are actually performed today. Furthermore, how you specifically performed your job may have differed meaningfully from the generic DOT description.

Strategies here include:

• Complete a detailed Work History Report (SSA-3369). Be specific and accurate about the actual demands of every past job: exactly how much you lifted, how long you sat/stood/walked, whether the job required reaching overhead, etc.
• Argue composite jobs. If your job combined elements of two different DOT occupations, it may be a "composite job" that doesn't neatly fit the DOT description — making it harder for SSA to claim you can return to it.
• Challenge DOT classifications. If SSA classified your job at a lower exertional level than it actually required, your representative can argue SSA used the wrong DOT code.

The Role of Vocational Experts at the Hearing

At the ALJ hearing, vocational experts (VEs) testify about how past jobs are classified and whether someone with your RFC could perform them. Your representative can cross-examine the VE about:

• Whether your job was correctly classified under the DOT
• Whether your job was actually a composite of multiple DOT occupations
• Whether the job, as you specifically performed it, had demands that exceed your RFC
• Whether your additional limitations — not captured in the judge's hypothetical — would preclude past work performance

What to Do If You're Denied at Step 4

1. File your appeal within 60 days of the denial notice
2. Get your treating physician to complete a detailed RFC assessment
3. Document in writing exactly how your past job was performed — every physical demand, every mental requirement
4. Gather updated medical evidence, including records from all treating specialists
5. Get professional representation — Step 4 and Step 5 arguments are where experienced advocates make the biggest difference
