How to Get a Nexus Letter for a VA Claim

To get a nexus letter, you gather your service and medical records, find a licensed provider qualified to address your condition, and ask them to review the file and give a written opinion on whether your condition is related to service. Most veterans start with their own treating provider, and many end up looking elsewhere, not because the claim is weak, but because a lot of providers are unfamiliar with what the U.S. Department of Veterans Affairs (VA) is actually asking for. Either way, the work you do before the appointment shapes the quality of what you get.

Key takeaways

Preparation drives quality. An opinion written without service treatment records is easy for the VA to discount. Assembling the file first is the highest-leverage step in the whole process.
You have more than one option. Your VA provider, a private treating physician, or an independent physician can all write one, and a “no” from the first is not the end of it.
Cost and timing vary widely. Independent opinions are typically self-pay and generally run from a few hundred dollars into four figures depending on complexity. No provider can promise a favorable conclusion.

Step 1: Gather your records before you ask anyone

A provider can only opine on what they can see, and an opinion that doesn’t reference your service records is one the VA can set aside as unsupported.

Pull together:

Your DD214 or other separation documents.
Service treatment records (STRs), including sick call notes, entrance and separation exams, and anything documenting the injury, illness, or exposure.
Personnel records that establish where you served and what your job was. Military occupational specialty and deployment history often matter more than veterans expect, especially for exposure and noise-related claims.
Current medical records showing the diagnosis and ongoing treatment.
Test results and imaging: a sleep study, audiogram, pulmonary function test, MRI, or lab work.
Your personal statement describing what happened in service and how symptoms have progressed since.
Supporting statements from family or people you served with, particularly for events that never made it into a medical record.
Any prior VA rating decision or denial letter. The denial letter tells you exactly which element the VA found lacking. Read it before you assume a nexus opinion is what’s missing.

The VA’s own page on evidence needed for a disability claim is a useful checklist here, and its Fully Developed Claims program is built around submitting a complete package up front.

Step 2: Decide who to ask

Three realistic paths, each with real trade-offs.

Your VA provider. Their opinion carries the same legal weight as any private opinion. They already have access to much of your record. They are also not obligated to write one, and many decline.

Your private treating physician. They know your history and have often been treating the condition for years, which is genuinely valuable context. The common obstacle is unfamiliarity with VA standards. A physician who has never written one may not know that “possibly related” reads as speculation.

An independent physician. A provider you engage specifically for the opinion, who reviews your records and evaluates you. There’s no treatment history, but there is usually familiarity with what the opinion needs to address. This is typically self-pay.

For complex conditions, specialty matters. A psychiatrist or psychologist on a mental health claim, a pulmonologist on a respiratory claim, an audiologist or ENT on a hearing claim. A specialist’s reasoning in their own field tends to be harder to dismiss than a generalist’s.

If your own provider has already declined and you’re deciding where to go next, our VA nexus letter and independent medical opinion service exists specifically for veterans in that position.

Step 3: Make the ask clearly

Providers say no far more often to a vague request than to a specific one. Instead of “can you write me a nexus letter,” try something closer to:

“I’m filing a VA disability claim for [condition]. I have my service treatment records showing [event or exposure]. Would you be willing to review them and give a written opinion on whether my current condition is at least as likely as not related to that? I can bring everything to the appointment.”

That does three things: it names the condition, it hands them the evidence, and it uses the VA’s own standard, which signals that you’re not asking them to guess.

Step 4: The evaluation and review

Whoever writes the letter needs time with the record. A thorough opinion generally involves a review of the service records alongside current treatment records, an evaluation or clinical interview, and a written analysis explaining the reasoning.

At HealthSource, this is a video appointment with a board-certified physician, with the opinion delivered afterward through the secure patient portal. Timing depends heavily on how many records there are to review. A claim with a thin file and a clear event moves faster than one with three decades of treatment history. Patients must be physically located in a state where the provider is licensed at the time of the visit.

What does a nexus letter cost?

There’s no standard rate. Independent medical opinions are generally self-pay, since the VA does not reimburse veterans for privately obtained evidence, and pricing across the market ranges from a few hundred dollars to several thousand depending on the condition, the volume of records, and whether a specialist is involved.

At HealthSource Medical Associates, a VA independent medical opinion (nexus) evaluation is $479.00 and includes the video visit with a board-certified physician. We’re a self-pay practice: no insurance is billed directly, no membership fees, and a superbill is available on request if you want to attempt out-of-network reimbursement. HSA and FSA payments are accepted.

Some treating providers write one at no charge as part of your existing care. It’s always worth asking before you pay.

How long does the claim take after you submit it?

The letter is one input; the VA’s timeline is separate. The VA publishes its own current processing average. As of July 2026, it reported an average of 68.6 days to complete disability-related claims, though individual claims vary considerably based on complexity and whether an exam is scheduled.

Two things are worth knowing while you wait. You generally have up to a year from the date the VA receives your claim to submit additional evidence. And if the VA schedules a claim exam (C&P exam), attend it. A missed exam can affect the outcome regardless of how strong your private evidence is.

What to do if your doctor says no

This is common, and it usually isn’t a judgment about your claim.

Ask why. “I’m not comfortable opining on events I didn’t witness” is a different problem than “I don’t have time for the paperwork,” and only one of them is solved by handing over your service records.
Offer the records. Many refusals are really about not having the evidence to reason from.
Ask a specialist instead. Your primary care provider may decline where a specialist treating the same condition would not.
Ask a different provider in the same practice.
Seek an independent opinion. A physician who regularly writes these knows what the opinion has to address.
Talk to an accredited representative. A Veterans Service Organization (VSO) representative, accredited attorney, or claims agent can tell you whether a nexus opinion is even the gap in your claim. The VA’s directory to get help from an accredited representative is free to use, and many VSOs charge nothing.

Red flags when paying for a nexus letter

Because this is a paid market, it attracts some bad actors. The VA has publicly cautioned veterans about fraud involving claim documentation. Be skeptical of:

A guaranteed favorable opinion. No honest provider can promise a conclusion before reviewing the evidence. An opinion that was decided before the records were read is worth very little to a VA rater.
A promised rating percentage. Ratings are VA determinations tied to the rating schedule, not something a private provider assigns.
No records review. A letter generated from a five-minute questionnaire will read like one.
A template with your name dropped in. Generic letters are recognizable, and they get weighed accordingly.
Fee arrangements tied to your back pay by anyone who is not a VA-accredited attorney or agent operating under the rules that govern accredited representation.

Common mistakes that weaken the letter

Submitting an opinion that never mentions the service records.
Accepting tentative language such as “may be,” “could be,” or “cannot be ruled out.”
A conclusion with no medical rationale behind it.
Chasing a nexus letter when the actual gap is a missing current diagnosis or an undocumented in-service event.
Forgetting to submit it. Evidence only counts once it reaches the VA, and the VA explains how to upload supporting documents online.

Ready to move forward?

If your own provider can’t or won’t address the question, a board-certified physician at HealthSource Medical Associates can review your records and provide an independent medical opinion. The VA nexus letter and independent medical opinion evaluation takes place over secure video, with documentation delivered through your patient portal.

We’ll say plainly what we can and can’t do: our physicians give an opinion that follows the evidence, which sometimes means a conclusion that doesn’t help a claim. We are not accredited to represent veterans before the VA, and no medical opinion guarantees an outcome. If that’s the kind of evaluation you’re looking for, you can book an appointment and bring your records.

When to seek medical attention

Building a claim is not the same as treating a condition, and the claims process is slow enough that symptoms can change meaningfully while you wait. Contact a healthcare provider if your symptoms worsen, if something new appears, or if a condition you’ve managed for years starts interfering with work or daily life. Virtual primary care can help maintain continuity while a claim is pending, and ongoing treatment records strengthen the claim as a side effect.

If you are having thoughts of suicide or self-harm, call or text 988 and press 1 for the Veterans Crisis Line, or visit VeteransCrisisLine.net. This is not an emergency service. In an emergency, call 911 or go to the nearest emergency room.

Frequently asked questions

Can I write my own nexus letter? No. The nexus opinion has to come from a qualified medical professional. Your own account of what happened in service is valuable evidence. It’s just a different kind, submitted as a personal statement.

Will the VA pay for my nexus letter? No. Privately obtained evidence is at your own expense. Some treating providers write one without charging.

Do I need one for every condition I’m claiming? Not necessarily. Some conditions are granted on a presumptive basis with no nexus opinion required. Our guide on whether you need a nexus letter for your claim covers how to tell the difference.

Can I get a nexus letter through telehealth? Yes. What matters is the qualification of the provider and the quality of the record review, not whether the evaluation happened in an exam room. You do need to be physically located in a state where the provider is licensed at the time of the visit.

What if I already got denied? A denial isn’t the end of the road. The VA offers several decision review options, and a supplemental claim allows you to submit new and relevant evidence. Read the denial letter carefully first, because it identifies which element the VA found unproven.

How is this different from a DBQ? A Disability Benefits Questionnaire captures clinical findings in the VA’s standardized format and speaks mainly to severity, while a nexus letter argues causation. The two documents work well together, and neither one substitutes for the other.
