Look At Specific Functions
Physical functions can include sitting, standing, walking, lifting, carrying, reaching, handling, and environmental tolerances. Mental functions can include understanding instructions, maintaining attention, interacting with others, and responding to workplace demands or changes.
The assessment should address sustained functioning, not just a single maximum effort. Explain how symptoms change over time and what happens when an activity is repeated. Medically supported limitations from multiple impairments must be considered together, including relevant limitations from impairments that are not individually severe.
Understand The Evidence Behind RFC
Treatment records, examination findings, testing, medical opinions, your statements, and other relevant evidence can contribute. An opinion is more useful when it explains the limitations and the medical support rather than merely declaring that you cannot work.
For claims governed by current medical-opinion rules, SSA evaluates supportability and consistency, among other factors. A specialist or longtime provider can offer important insight, but the relationship alone does not guarantee that SSA will accept the opinion. The agency is responsible for the RFC finding.
Know How RFC Relates To Work
At step four, SSA compares RFC with qualifying past work as you actually performed it and as it is generally performed. The relevant period is generally five years, with claim-specific anchors and additional requirements about duration and earnings. The old blanket fifteen-year description is outdated.
If you cannot perform past relevant work, SSA proceeds to the other-work question. Age, education, skills, and the supported limitations matter. Labels such as “sedentary” or “light” do not capture every restriction; hand use, mental demands, and other limitations can require additional analysis.
Prepare Examples That Help
Write down activities that illustrate the problem: needing to change position, losing track of instructions, requiring assistance, or recovering after exertion. Include how often this happens and what treatment records show. Do not invent precise absence or off-task percentages to fit a perceived rule.
An RFC disagreement is best approached by identifying which functions SSA evaluated incorrectly and what evidence supports a different finding. If a notice denies benefits, preserve the appeal deadline while you investigate the missing or misunderstood evidence.
