Facing VA Denial for Cancer & Toxic Exposure Claims?

Many veterans face denials not because their condition lacks merit, but because the medical connection to service has not been clearly explained. A specialty medical nexus opinion may help clarify complex medical issues, strengthen limited documentation, and address overlooked diagnoses, including concerns affecting women veterans.

To better understand the process, what is included, and what to expect, please review the FAQ section below.

Independent Medical Opinion (IMO)

An Independent Medical Opinion (IMO) is a focused physician review of relevant medical records to determine whether a medically supportable connection, or “nexus,” exists between a current condition and military service.A specialty IMO may be helpful in situations such as:

  • when a cancer or other condition is not clearly considered presumptive under the PACT Act, but the medical history, exposure history, and biologic plausibility warrant careful review

  • when the VA has reduced benefits after treatment, but important questions remain about ongoing active treatment, residual effects, or severity

  • when a DIC review may help clarify whether a veteran’s death was related to cancer, toxic exposures, service-connected conditions, or military service

  • when a medically complex case requires thoughtful review of records, clinical history, and relevant medical literature to better explain causation and severity

Frequently Asked Questions

What is a Nexus Letter and why might I need one? +
A Nexus Letter is a document written by a medical professional that explains whether there is a medically supportable connection between a current health condition and military service. It may be helpful when additional medical explanation is needed to clarify service connection, especially in more complex cases such as toxic exposures, secondary conditions, cancer-related claims, or DIC-related review.
What is the VA Case Strategy Consult? +
The VA Case Strategy Consult is the first step in the process. It is a focused 40-minute consultation to discuss the diagnosis, service history, medical timeline, and overall concerns to help determine whether the case appears medically appropriate for a comprehensive nexus opinion review.
Does the VA Case Strategy Consult include review of my medical records? +
No. The VA Case Strategy Consult does not include physician review of uploaded medical records. It is based on the information provided through the intake process and the discussion during the consultation.
Why is the consult separate from the Comprehensive Nexus Opinion Package? +
The consult serves as a focused screening and strategy step. It helps clarify whether a full physician records review is appropriate before moving into a more detailed and time-intensive process.
What information should I have ready before scheduling a consultation? +
It is helpful to have the veteran’s service history, diagnosis, treatment history, timeline of symptoms, and any relevant VA decision letters available. The VA Case Strategy Consult is based on the information shared in advance and discussed during the consultation.
Does scheduling a VA Case Strategy Consult guarantee a nexus letter? +
No. The consultation is a required first step and helps determine whether a nexus opinion may be medically supportable. A formal nexus opinion is only provided when the medical evidence reasonably supports a connection between the veteran’s condition and military service.
Will I automatically qualify for the Comprehensive Nexus Opinion Package after the consult? +
Not necessarily. The consult helps determine whether the case appears medically appropriate for comprehensive review. Some cases may not be suitable for a formal nexus opinion.
How will I know whether my case is appropriate to move forward? +
After the VA Case Strategy Consult, you will be informed whether the case appears appropriate for comprehensive review and what the next steps would be.
What is included in the Comprehensive Nexus Opinion Package? +
The Comprehensive Nexus Opinion Package includes physician review of up to 50 pages of records, detailed medical analysis, draft preparation, a 10-minute virtual/video draft review, and final signed opinion letter delivery when medically appropriate.
How much does the Comprehensive Nexus Opinion Package cost? +
The Comprehensive Nexus Opinion Package is $2,100 for physician review of up to 50 pages of records. A VA Case Strategy Consult ($250) is required before moving forward with the package.
What is the total cost if I move forward after the consult? +
The total cost is $2,350, which includes the $250 VA Case Strategy Consult and the $2,100 Comprehensive Nexus Opinion Package.
Do I have to pay the full package fee upfront? +
No. The Comprehensive Nexus Opinion Package is paid in three non-refundable stages:

$800 to open the case and begin records intake
$700 after detailed physician review, draft preparation, and 10-minute virtual/video draft review
$600 before the final signed opinion letter is released
Are payments refundable? +
No. Payments are non-refundable because each phase involves physician time, professional review, and case development.
What is the turnaround time for a nexus letter? +
Estimated turnaround is approximately 3 weeks from the date all required records, forms, and payments are received. This timeframe may vary depending on record volume, case complexity, and response time for requested information.
What happens if my records exceed 50 pages? +
If the submission exceeds 50 pages, an additional fee of $200 per 20-page increment will apply for further physician review.
What kinds of records should I submit? +
Please submit only records directly relevant to the condition being reviewed. This may include key service records, pertinent medical records, specialist notes, pathology reports, imaging reports, operative reports, and other supporting records related to the medical question at issue.
What if I submit duplicate or unrelated records? +
Duplicate, irrelevant, or excessively disorganized records may require additional review fees and may delay the review process.
Does payment guarantee a favorable nexus opinion? +
No. Payment covers the physician’s time, review, analysis, and professional medical opinion. A favorable opinion can only be provided when medically appropriate and supportable based on the records and facts of the case. Final decision is rendered by the VA.
How does your service differ from what my regular doctor can provide? +
A treating physician may know the medical history well, but may not always have the time or willingness to prepare a detailed medical opinion. This is a specialty service that requires in-depth knowledge of toxin exposure, cancer biology, latency, etc., and provides a focused, independent physician review of the medical facts, service history, and supporting records to determine whether a medically supportable nexus opinion can be provided.
What types of toxic exposure cases do you review? +
Cases may include a variety of military toxic exposures and medically complex service-related questions, including radiation exposure, burn pits, PFAS, asbestos, jet fuel, industrial solvents, pesticides, contaminated water, and other hazardous exposures encountered during military service. Each case is individually reviewed based on the available medical records and service history.
How do you address women veterans’ specific health concerns? +
Women veterans may experience unique patterns of exposure and health effects that deserve careful medical consideration. Reviews are approached thoughtfully, with attention to gender-specific medical issues, cancer-related concerns, reproductive health considerations, and other conditions that may be overlooked in more generalized evaluations.
Do you review cases for DIC (Dependency and Indemnity Compensation) claims? +
Yes. Cases involving DIC claims may be reviewed when a medical nexus opinion could help clarify whether a veteran’s death was related to military service, service-connected conditions, or toxic exposures. Each case is individually evaluated based on the medical records and service history.
What if my claim has already been denied? +
A prior denial does not automatically mean the case cannot be reviewed. In some situations, a more focused medical analysis may help clarify the medical issues involved. Each case is assessed individually to determine whether a medically supportable opinion can be offered.
