Federal employees with serious medical conditions may reach a point in time when continuing to perform the essential functions of their position is no longer medically sustainable.
At that stage, the question is no longer whether symptoms are present—but whether the condition, in practical terms, prevents reliable performance of required duties.
Our practice provides independent, physician-authored medical opinion letters for federal employees pursuing Disability Retirement through the Office of Personnel Management (OPM).
Each case is approached with careful attention to medical detail, functional impact, and the specific demands of your role.
Disability retirement decisions are not based on diagnosis alone.
They require a clear, medically supported explanation of how a condition translates into functional limitation—and why those limitations prevent continued performance of essential job duties.
In many cases, the medical record contains the necessary information, but it is:
A physician-authored medical opinion can help bring these elements together into a structured, medically coherent assessment.
This work is grounded in training and experience in occupational medicine—a field focused on evaluating how medical conditions affect an individual’s ability to perform job-related duties. This includes assessing functional capacity, work restrictions, and the practical demands of specific roles.
That perspective is particularly relevant in disability retirement evaluations, where the determination depends on whether a condition prevents reliable performance of essential job functions over time.
All Federal Disability Retirement reports are authored by a physician with experience in occupational and disability-related medical evaluations. Read Dr. David's Bio.
A formal medical opinion may be particularly helpful when:
Our role is not to advocate, but to clarify. Our physician translates clinical findings into a medically sound explanation of work-related limitations.
Each case is evaluated based on:
Where appropriate, the resulting opinion addresses whether the condition impairs the ability to perform required duties in a consistent and reliable manner, based on the available medical evidence.
We use a structured, stepwise approach to ensure that any opinion is medically appropriate and well-supported. Fees are in accordance with our standard nexus letter fees.
A focused physician review to determine whether a medical opinion supporting disability retirement is supportable based on current documentation. This step helps avoid unnecessary expense in cases where:
Note that if disability retirement is found to be medically supported, the fee for the Level 0 review is applied toward a Level 2 or Level 3 service.
A detailed written report that includes:
Includes all of Level 1, along with a written summary of all records reviewed to strengthen the medical and legal clarity of your claim
Includes all of Level 2, along with a 30-minute direct physician consultation to further clarify the clinical context and ensure accuracy of the report.
Not all medical conditions meet the threshold for disability retirement.
In some cases:
For this reason, all opinions are objective, evidence-based, and independent of outcome.
Many federal employees initially pursue workplace accommodations and later consider disability retirement as their condition evolves.
If you are still working and exploring whether accommodations may be sufficient, you may wish to review Medical Opinion Letters for Federal Disability Accommodations.
Understanding where your situation falls along this spectrum can help guide the most appropriate next step.
If you are considering Federal Disability Retirement—or need a clearer understanding of whether your medical condition meets the clinical threshold—the appropriate starting point is a structured medical record review.

The Office of Personnel Management (OPM) requires medical documentation demonstrating that a federal employee has a medically determinable condition that prevents them from performing the essential duties of their position.
This typically includes evidence of:
A medical opinion can help present these elements in a clear, clinically organized manner.
A diagnosis alone is not sufficient.
The central issue in disability retirement is functional impact -- in other words, how the condition affects your ability to perform required job duties on a consistent and reliable basis.
Two individuals with the same diagnosis may have very different levels of functional impairment, which is why a structured medical assessment is often important.
A medical opinion helps translate clinical findings into a clear explanation of work-related limitations.
In many cases, treatment records document symptoms and diagnoses, but do not directly address how those conditions affect the ability to perform job duties.
A physician-authored opinion can help connect these elements in a way that is medically coherent and relevant to the disability determination process.
In some cases, denials occur because the medical documentation does not clearly explain functional limitations or their impact on job performance.
A structured medical record review can help determine whether:
Occupational medicine focuses on how medical conditions affect an individual’s ability to perform job-related tasks.
This includes evaluating:
This perspective is directly relevant to disability retirement evaluations, where the key question is whether a condition prevents reliable performance of essential duties over time.
The most appropriate first step is a Level 0 structured medical record review and case assessment.
This allows our physician to assess whether your condition, medical documentation, and job demands support a medically sound opinion before proceeding to a full report.
No. No ethical medical provider can guarantee approval. The Office of Personnel Management (OPM) is the agency that makes the initial and final decision on whether an employee is eligible.
All of our medical opinions are objective and based on the available evidence. Some cases support a clear connection between medical conditions and work limitations. Others may require additional documentation, or may not support a favorable opinion.
