It is possible to receive disability benefits from the Social Security Administration (SSA) for Parkinson’s Disease (PD). Parkinson’s Disease is a progressive neurological disorder that impacts movement by causing the loss of dopamine-producing neurons in the brain. As the condition advances, its motor and non-motor symptoms can severely limit a person’s ability to work full-time. The SSA administers two main federal programs designed to provide financial support to people with disabilities: Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI). To qualify for either program, the limitations caused by PD must meet the SSA’s strict definition of disability, which focuses on the inability to engage in Substantial Gainful Activity (SGA).
Medical Requirements for Approval
The SSA evaluates Parkinson’s Disease under its Listing of Impairments, specifically section 11.06, which addresses Parkinsonian Syndrome. A diagnosis of PD alone is generally not enough for approval; the determination rests on the severity of the functional limitations that persist despite adherence to prescribed medical treatment for at least three consecutive months. The primary medical evidence needed is documentation from a neurologist that details the extent of motor and cognitive impairment.
One way to meet the listing is to show extreme disorganization of motor function in two extremities. This limitation must be so significant that it causes an extreme inability to stand up from a seated position, maintain balance while walking or standing, or use the upper extremities for fine and gross motor tasks. This criterion focuses directly on the motor symptoms of Parkinson’s, such as rigidity, bradykinesia (slowness of movement), and resting tremor.
If the motor function criteria are not fully met, an applicant may still qualify by demonstrating a combination of physical and mental limitations. This secondary path requires medical evidence of a marked limitation in physical functioning, coupled with a marked limitation in one of four specific mental functioning areas:
- Understanding, remembering, or applying information
- Interacting with others
- Concentrating, persisting, or maintaining pace
- Adapting or managing oneself
When the symptoms do not precisely meet the requirements of Listing 11.06, the SSA will conduct a Residual Functional Capacity (RFC) assessment. The RFC is an in-depth evaluation of what the applicant can still physically and mentally do despite their impairments. It considers the ability to lift, carry, stand, sit, walk, and handle workplace stressors over an eight-hour workday. If the RFC shows that the individual cannot perform their past work or any other type of work that exists in significant numbers in the national economy, they may be found disabled.
Differentiating SSDI and SSI Programs
The two federal disability programs, Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI), have distinct eligibility requirements, though both use the same medical definition of disability. SSDI is a program for individuals who have worked long enough and recently enough to have paid Social Security taxes. Eligibility for SSDI is not based on current income or assets, but rather on the applicant’s prior contributions to the Social Security system through payroll taxes.
Once approved, SSDI benefits are typically paid monthly, and recipients usually become eligible for Medicare coverage after a waiting period. The amount of the monthly benefit is calculated based on the individual’s average lifetime earnings before they became disabled. The work credit requirement means that if a person has not worked for a significant period before the onset of their disability, they may not qualify for SSDI.
Supplemental Security Income (SSI), on the other hand, is a needs-based program that does not rely on an applicant’s prior work history or paid taxes. SSI provides monthly payments to disabled adults and children who have very limited income and resources. This program is funded by general tax revenues, not the Social Security trust funds.
The financial limits for SSI are strict, requiring the applicant’s countable assets to be below a certain low threshold. A person with Parkinson’s Disease may qualify for one program, or both, depending on their work history and their current financial status.
The Process of Filing and Appealing a Claim
The disability application process begins with the submission of a formal application to the SSA, which includes a detailed description of the medical condition and how it limits the ability to work. Gathering comprehensive medical evidence is the single most important step in this initial phase. This evidence should include all records from neurologists and other treating physicians, diagnostic test results, medication lists, and statements detailing the functional limitations caused by PD.
Many applicants also submit a Residual Functional Capacity (RFC) form completed by their treating physician detailing the individual’s specific limitations. Since Parkinson’s Disease is a progressive condition, an applicant with an aggressive or advanced form may have their case flagged for expedited review under the Compassionate Allowances (CAL) program.
If the initial application is denied, the applicant has the right to begin a multi-tiered appeal process. The first level of appeal is a Request for Reconsideration, where the case is reviewed by a different examiner who may consider new evidence. If the denial is upheld at this stage, the next step is to request a hearing before an Administrative Law Judge (ALJ).
This ALJ hearing is often the most successful stage for applicants, as it provides an opportunity to present evidence and testimony in person. If the ALJ also issues an unfavorable decision, the next level is a review by the SSA’s Appeals Council. The final step in the process, if all previous appeals fail, is to file a lawsuit in Federal District Court. Applicants must adhere to strict 60-day deadlines for filing an appeal at each stage of the process.
