Search “nexus letter for VA claim” and you will find companies charging anywhere from $200 to $1,500 for a medical opinion letter. Some of those companies are run by physicians. Many are not. Almost all of them are unnecessary — and some are operating illegally under both federal law and California SB 694 (2026).

What the Nexus Letter Industry Charges

The paid nexus letter market operates primarily in two forms. The first is standalone nexus letter services, where a contracted physician reviews your records and writes an opinion letter for a flat fee ranging from $200 to $800. The second is bundled claims services, where a company charges $1,000 to $3,000 or more for a “complete claims package” that includes nexus letter procurement as one component.

Neither is legally required. And the bundled version — where a company charges fees for helping you prepare, present, or prosecute a VA claim and bundles a nexus letter into that package — is illegal under 38 U.S.C. § 5904 and California SB 694 (2026) when the company is not VA-accredited.

Why You Can Get One for Free

A nexus letter is a medical opinion. Medical opinions come from physicians, nurse practitioners, physician assistants, psychologists, and other licensed healthcare providers — the same professionals you already have relationships with through your civilian medical care or the VA healthcare system.

Your treating physician can write a nexus letter as part of your ongoing care. There is no requirement that it come from a specialist you pay to evaluate you once. In fact, an opinion from a provider who has treated you over time — and who can reference that treatment history — carries more weight with VA adjudicators than a one-time opinion from a contracted physician who has never met you.

Your free, accredited VSO can provide your treating physician with a template and a clear explanation of the VA’s standard. Most physicians who understand what they are being asked to write will cooperate. The letter costs you nothing beyond your regular medical appointment.

When a Paid Independent Medical Examination Makes Sense

There are legitimate situations where paying for an independent nexus opinion is reasonable — not because you cannot get one free, but because the specific circumstances of your claim require a specialist’s opinion that your treating physician cannot provide.

If your C&P examiner gave an unfavorable nexus opinion and you are filing a supplemental claim, you need a nexus letter that directly addresses and rebuts that opinion with clinical reasoning. In that context, an independent medical evaluation from a specialist in the relevant field — cardiology, psychiatry, orthopedics — can be worth the cost because it gives the VA a stronger competing opinion to weigh.

Similarly, for complex secondary service connection claims involving conditions where the medical literature on causation is nuanced, a specialist’s opinion with citations to peer-reviewed research can significantly strengthen a claim that a general practitioner’s letter might not adequately support.

In these cases, the cost is a strategic decision — not a necessity. Discuss it with your accredited VSO before spending anything.

How to Identify Illegal Fee-Charging Services

Under 38 U.S.C. § 5904, only VA-accredited attorneys, claims agents, and VSO representatives may charge fees for claims assistance — and accredited attorneys and agents may only charge fees after a claim has been fully decided and during the appeals process. Before a claim is decided, representation must be free.

California SB 694 (2026) extends these protections explicitly at the state level, making it easier to take action against unaccredited operators in California. If a company is:

– Charging you a fee before your initial claim is decided
– Offering to “prepare your claim,” “maximize your rating,” or “get you the benefits you deserve” in exchange for payment
– Bundling nexus letter procurement into a paid claims preparation package

…that company is likely operating in violation of federal law and California law. Report them to the VA’s Office of General Counsel and the California Department of Veterans Affairs.

The Free Path: Step by Step

Step 1: Contact a free, accredited VSO — the DAV, VFW, American Legion, or AMVETS. Tell them you need help obtaining a nexus letter for your VA claim.

Step 2: Your VSO will help you identify which conditions need nexus letters and provide guidance on the VA’s evidentiary standard.

Step 3: Request a nexus letter from your treating physician. Bring your VSO’s template guidance to the appointment. Explain the “at least as likely as not” standard and what records the doctor should reference.

Step 4: Review the draft letter with your VSO before submitting it with your claim. They can flag language issues before they reach a VA adjudicator.

Frequently Asked Questions

How much does a nexus letter cost?
From your own treating physician, a nexus letter should be free or covered under a standard medical appointment. Independent specialist opinions cost $200 to $800 in most markets. Bundled claims packages that include nexus letters can charge $1,000 to $3,000 — many of which are illegal under 38 U.S.C. § 5904 and California SB 694.

Is it illegal to charge for a nexus letter?
Charging for a nexus letter as a standalone medical service from a licensed physician is legal. Charging fees for preparing, presenting, or prosecuting a VA claim — including as part of a package that includes a nexus letter — is illegal for non-accredited individuals under 38 U.S.C. § 5904 and California SB 694.

Does a paid nexus letter perform better than one from my own doctor?
Not necessarily. The quality of a nexus letter depends on the provider’s credentials, their familiarity with your case, and the clarity of their reasoning — not the fee charged. An opinion from a long-term treating physician who knows your history often outperforms a one-time contracted evaluation.

Where do I report a company charging illegal VA claims fees?
Report to the VA’s Office of General Counsel at 1-800-827-1000, the California Department of Veterans Affairs (CalVet) at 1-844-MyCalVet, or your state’s attorney general office.
