To prove the severity of an impairment, what must the applicant present?

To establish the severity of an impairment when applying for Social Security Disability Insurance (SSDI), the applicant is required to present documented medical evidence indicating the severity of their condition. This medical evidence typically includes detailed records from healthcare providers, test results, treatment plans, and any other relevant documentation that can substantiate the claim. The Social Security Administration (SSA) relies on this objective data to assess not only the diagnosis but also how the impairment limits the applicant's ability to perform basic work activities.

Documented medical evidence is crucial because it offers an unbiased and authoritative perspective on the individual's health status and functional capabilities. In contrast, personal statements, general knowledge, or letters from employers do not provide the same level of substantiated proof needed for an effective evaluation of the claim. While personal statements and employer letters can occasionally supplement medical evidence, they cannot replace the rigorous documentation required to demonstrate the severity of an impairment.
