One of the most frustrating experiences for a Social Security Disability applicant is receiving a denial despite genuinely being unable to work. The applicant may have stopped working because of a serious medical condition, undergone extensive treatment, and provided Social Security with medical records, yet still receive a letter stating that the claim has been denied.
A denial does not necessarily mean that the Social Security Administration believes nothing is wrong with the applicant. Instead, SSA applies a specific legal and medical framework when deciding whether someone is disabled. A person can have a serious medical condition and significant limitations without the initial application containing enough evidence to establish disability under those rules.
Understanding why claims are denied can also help applicants understand what may need to be addressed during an appeal.
Is Having a Serious Medical Condition Enough to Qualify for Disability?
Not necessarily.
Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are not awarded simply because an applicant has been diagnosed with a particular illness or injury. Generally, SSA must determine that a medically determinable physical or mental impairment prevents the individual from engaging in substantial gainful activity and has lasted, or is expected to last, for at least 12 months or result in death.
The diagnosis establishes that a medical condition exists. The disability determination focuses heavily on what that condition prevents the person from doing.
For example, medical records may clearly establish that an applicant has degenerative disc disease. But SSA may still want evidence showing how the condition affects the person’s ability to sit, stand, walk, lift, carry, bend, concentrate, maintain attendance, and perform other activities required in a workplace.
This distinction between diagnosis and functional limitation is one of the most important concepts in a Social Security Disability claim.
Can Social Security Deny a Claim Because There Is Not Enough Medical Evidence?
Yes. Insufficient medical evidence is a common problem in disability claims.
An applicant may have a genuine disability but medical records that do not fully document its severity. Records might contain diagnoses, medication lists, and brief descriptions of symptoms without explaining how significantly those symptoms interfere with everyday functioning.
Gaps in medical treatment can also make a claim more difficult to evaluate. SSA may have limited evidence showing how a condition progressed or how long significant limitations existed.
Diagnostic testing, specialist evaluations, treatment history, clinical findings, hospital records, medication history, and other medical documentation can all contribute to the overall disability record.
The issue is not simply how many medical records exist. The evidence must help establish the nature, severity, duration, and functional effects of the applicant’s impairments.
Why Does Social Security Look at What an Applicant Can Still Do?
SSA evaluates an applicant’s residual functional capacity, commonly called RFC.
RFC represents the most an individual can still do despite limitations caused by medically determinable impairments. Depending on the claim, SSA may evaluate abilities such as sitting, standing, walking, lifting, carrying, reaching, following instructions, concentrating, interacting with others, maintaining pace, and adapting to workplace conditions.
This can lead to a frustrating result for applicants.
An applicant may know that returning to a physically demanding former job is impossible. SSA may agree. But that does not necessarily end the disability evaluation.
The agency may then consider whether the applicant retains the capacity to perform other work.
Can SSA Deny a Claim Even If You Cannot Return to Your Previous Job?
Yes.
Social Security’s disability evaluation is not limited to whether someone can return to a particular employer or previous occupation.
SSA considers whether an applicant can perform past relevant work. If the answer is no, the analysis may proceed to whether the person can adjust to other work, considering factors such as residual functional capacity, age, education, and work history.
This is why an applicant who spent many years performing heavy physical work may still receive a denial even though everyone agrees that the individual can no longer perform that particular job.
SSA may conclude that the applicant can perform work with fewer physical or mental demands.
Whether that conclusion accurately reflects the applicant’s limitations can become an important issue in an appeal.
Can Symptoms Such as Pain and Fatigue Support a Disability Claim?
Yes, but subjective symptoms generally need to be evaluated in connection with the medical evidence and the overall record.
Chronic pain, fatigue, dizziness, shortness of breath, headaches, medication side effects, difficulty concentrating, and similar symptoms can substantially interfere with a person’s ability to work.
The challenge is demonstrating their severity, persistence, and functional effects.
For example, stating that someone experiences severe fatigue is important, but medical and other evidence showing how frequently the fatigue occurs, what causes or worsens it, what treatment has been attempted, and how it affects the ability to maintain a normal workday may provide a more complete picture.
Consistency throughout the record can be important when SSA evaluates these symptoms.
Can Multiple Medical Conditions Be Considered Together?
Yes.
Many disability applicants do not have one medical condition that independently explains every limitation. Instead, several physical and mental impairments may combine to make sustained employment difficult or impossible.
An individual might have back problems, arthritis, diabetes, neuropathy, anxiety, and medication side effects. Each condition may create limitations, and their combined effect can be greater than any one impairment considered by itself.
SSA is required to consider the combined effect of medically determinable impairments during the disability evaluation.
A complete application should therefore identify all relevant conditions and limitations rather than focusing exclusively on the diagnosis the applicant believes is most serious.
Can Failure to Follow Treatment Affect a Disability Claim?
Treatment history can become an issue in some claims.
SSA may consider whether prescribed treatment could be expected to restore an applicant’s ability to engage in substantial gainful activity and whether the applicant has good cause for not following that treatment.
There can be legitimate reasons why someone does not receive recommended care. An individual may experience serious side effects, be unable to afford treatment, lack access to appropriate medical services, or have other circumstances affecting treatment.
Applicants should not simply assume that gaps in treatment or decisions concerning medical care will be understood without explanation. The circumstances surrounding those issues may need to be documented.
Why Can an Initial Disability Application Be Denied Even When the Claim Is Legitimate?
A disability determination is based on the evidence SSA has when it reviews the claim.
The agency may not have received records from every provider. Medical records may not adequately describe workplace limitations. An applicant may have unintentionally provided incomplete information about previous employment or daily activities. A medical condition may also have worsened since the application was originally submitted.
In other cases, SSA may interpret the available evidence differently than the applicant or treating providers do.
For these reasons, an initial denial does not necessarily mean that the applicant cannot ultimately qualify for disability benefits.
What Should Someone Do After Receiving a Social Security Disability Denial?
A denial should be reviewed carefully, and an applicant who disagrees with the decision should pay close attention to the deadline for appealing.
Rather than simply submitting the same information again, an appeal provides an opportunity to determine why the claim was denied and whether the disability record needs to be strengthened.
That may involve obtaining updated medical records, identifying missing treatment, documenting additional diagnoses, clarifying the applicant’s past work, providing more information about functional limitations, or addressing SSA’s conclusion that the applicant can perform past or other work.
Continuing appropriate medical treatment while an appeal is pending can also be important because current records may document how the condition affects the applicant over time.
How Can a Social Security Disability Attorney Help After a Denial?
Social Security Disability claims involve much more than proving that an applicant has been diagnosed with a serious medical condition. The central question is whether the medical evidence and other information establish that the applicant is unable to engage in substantial gainful activity under Social Security’s disability rules.
Attorney Chris Sharry helps individuals pursuing SSDI and SSI benefits understand why claims have been denied and what evidence may be needed during the appeals process. An experienced Social Security Disability attorney can review the decision, examine the medical and vocational evidence, identify weaknesses or missing information, and help present a more complete picture of how an applicant’s conditions affect the ability to work.
Someone who genuinely cannot work should not assume that an initial denial is the final word. Understanding the reason for the denial and responding appropriately through the Social Security appeals process can be an important next step toward obtaining the benefits the applicant needs.
