You may benefit from a medical nexus evaluation if you:
Have a current medical diagnosis.
Believe your condition is related to military service.
Are pursuing secondary service connection.
Were denied because a medical nexus was not established.
Need an independent review of a C&P medical opinion.
Have new medical evidence for a Supplemental Claim.
Have records that were not previously considered.
Need clarification of a medically complex condition.
A VA nexus letter is a physician’s written medical opinion explaining whether your current medical condition is medically connected to your military service, or to another service-connected disability. For many VA disability claims, the evidence must establish three basic elements. When these elements are supported by the evidence, a medical nexus may exist.
These are the building blocks of a nexus:

You have a currently diagnosed physical or mental health condition.

An injury, illness, exposure, diagnosis, or other relevant event occurred during military service.

Medical evidence supports a relationship between the current condition and the in-service event, injury, illness, or exposure.
A physician evaluates whether a current medical condition may be related to an injury, illness, exposure, or event that occurred during military service.
A physician evaluates whether an existing service-connected disability may have caused or aggravated another diagnosed condition.
A detailed physician review may address conflicting evidence, a prior C&P examination, a previous negative opinion, or another medically complex issue affecting a VA disability claim.
A physician evaluates whether military service or an existing service-connected disability permanently aggravated another medical condition beyond its natural progression.
Our physicians review relevant service history, symptom progression, diagnostic records, headache logs, medical conditions, medication history, and other evidence when evaluating a possible medical relationship.
We evaluate appropriate cases involving the back, neck, joints, radiculopathy, chronic pain, altered gait, and related orthopedic conditions.
Our physicians review sleep studies, treatment history, relevant risk factors, service-connected conditions, medication history, symptom chronology, and available medical literature to determine whether an opinion is medically supportable.
We evaluate medically appropriate cases involving PTSD, depression, anxiety, adjustment disorders, and mental health conditions that may be secondary to chronic pain or another service-connected condition.
Our physicians evaluate whether the available medical evidence supports a medical opinion related to a VA Clothing Allowance claim. Evaluations may include review of your medical history, prescribed devices or medications, and their documented effects on clothing.
Our physicians evaluate how service-connected medical conditions affect functional abilities related to employment, education, and vocational rehabilitation. When medically appropriate, we provide an independent, evidence-based medical evaluation based on a comprehensive review of the available medical evidence and the veteran’s functional limitations.
Our physicians evaluate how medical conditions affect an individual’s ability to perform the essential functions of their occupation. When medically appropriate, we provide an independent, evidence-based medical evaluation supported by a comprehensive review of the available medical evidence and functional limitations.
Veterans who believe a medical condition may be related to military environmental or occupational exposures may benefit from an independent physician evaluation. Our board-certified physicians review the available medical evidence, exposure history, clinical findings, and relevant medical literature, when appropriate, to determine whether the evidence supports the requested medical opinion.

A Disability Benefits Questionnaire, commonly called a DBQ, is a standardized VA form used by a healthcare provider to document a diagnosis, symptoms, clinical findings, severity, and the functional impact of a medical condition.
Unlike a nexus opinion, a DBQ generally focuses on the current severity and clinical findings of a condition. It does not necessarily address whether the condition is connected to military service unless a separate medical opinion is requested.
| Medical Nexus Opinion | DBQ Evaluation | |
|---|---|---|
| Evaluates whether a condition is medically related to military service or an existing service-connected disability. | Documents the current severity, symptoms, and clinical findings of a condition. | |
| Includes medical causation analysis and supporting rationale. | Focuses primarily on examination findings and functional impairment. | |
| Results in a written physician medical opinion when medically supportable. | Results in a completed condition-specific VA questionnaire. | |

A nexus opinion is developed through an independent review of the diagnosis, relevant service history, medical records, clinical findings, risk factors, and applicable medical literature.
The physician reviews diagnostic records, treatment history, testing, and clinical documentation relevant to the condition.
The physician evaluates the relevant in-service event, exposure, injury, illness, or established service-connected condition.
The physician considers the medical history, clinical findings, chronology, alternative explanations, risk factors, and literature.
When medically supportable, the physician provides a written opinion explaining the conclusion and the reasoning behind it.
Relevant records may include service treatment records, VA and private medical records, diagnostic testing, prior decisions, examination reports, statements, and medical research.
The physician’s conclusion is based on the available evidence and clinical judgment. A favorable opinion is never guaranteed.
A VA nexus letter is a physician's written medical opinion explaining whether the available medical evidence supports a connection between your current medical condition and your military service—or between your current condition and an existing service-connected disability. A well-supported nexus letter explains the physician's medical reasoning, not simply a conclusion.
A medical nexus evaluation may be appropriate for veterans who:
Whether a medical opinion is appropriate depends on the individual circumstances of each case.
No. Every evaluation is based on the physician's independent medical judgment and the available evidence. If the physician determines that the requested opinion is not medically supportable, a favorable nexus opinion will not be provided.
Helpful records may include:
If you do not have every record available, your physician can discuss which records may be most helpful.
Yes. A secure telehealth evaluation with one of our board-certified physicians is required before a medical opinion can be considered. This allows the physician to obtain an appropriate medical history, clarify important details, and perform an individualized evaluation.
Physician evaluations are approximately 15 minutes. Additional time is spent outside of the appointment reviewing your records, analyzing the medical evidence, and preparing documentation when medically appropriate.
Our goal is to provide completed medical opinions within approximately one week of your physician evaluation. If a written medical opinion is prepared, it will be delivered securely through our patient portal.
Yes. When applicable, our physicians may review previous Compensation & Pension (C&P) examination reports as part of the overall medical record review and consider them along with the available medical evidence.
Yes. When requested, our physicians may evaluate whether the available medical evidence supports a relationship between a current condition and an existing service-connected disability, including whether the service-connected condition may have caused or permanently aggravated another condition.
If the physician determines that additional records, diagnostic testing, or specialist evaluation would be helpful before reaching a medical conclusion, you will be informed of the additional information needed.
