Twenty questions, answered straight

Questions Veterans Actually Ask

Not the questions a marketing department invented. These are the ones that come up on the phone, in the same order, week after week — and the honest answer to each one, with the regulation it comes from.

Almost every question below is really the same question wearing a different coat: am I already disqualified? Usually the answer is no, and the veteran has been sitting on a filable case for years because somebody at a counter, in a waiting room, or in a comment thread told him something that was not true. No diagnosis yet is not a disqualification. Nothing in the service record is not a disqualification. A denial from 2009 is not a disqualification. A blank exposure record is not proof that nothing happened to you.

Each answer below names the regulation or the case it comes from, so you can check it rather than take our word for it, and points to the page on this site where the whole subject is worked out in full. Nothing here is legal advice or medical advice, and we are not the VA. It is the plain version of what the rules actually say.

Before anything is filed

Where a toxic exposure claim actually starts

Most veterans stall out at the front of this process because they believe they are missing something they are not actually required to have yet. These four are the questions that keep files closed for years.

I know I was exposed, but I have never been diagnosed with anything. Is there anything to file?

Compensation is paid for a disability, not for an exposure — so without a current diagnosis there is normally no claim to grant. There is one real exception: under 38 CFR 3.317, a Gulf War or Southwest Asia theater veteran can be paid for a qualifying chronic disability that has no diagnosis at all, including an undiagnosed illness and a medically unexplained chronic multisymptom illness such as chronic fatigue syndrome, fibromyalgia, or a functional gastrointestinal disorder. Outside of that, the move is not to file into a void. The move is to get the exposure and the symptoms into a medical record now, so that when a diagnosis lands there is already a documented history behind it. Start with the talk to your doctor file and the exposure sheet.

Nothing in my service records says a word about the exposure. Is the claim dead?

No, and this is the single most common reason a good claim never gets filed. Almost nobody has an exposure written into their own service treatment record — the military was not documenting what you breathed. Exposure is proven with unit histories, deck logs, morning reports, travel and TDY orders, performance evaluations, base environmental records, photographs, and buddy statements, and for a great many veterans it is proven by the presumption instead, where the law accepts the exposure once the service is confirmed. VA also has its own exposure record system now — see TERA and ILER. What you write in your own statement counts too, and it counts more when it is specific: the place, the dates, the duty, and how the substance got into you.

Is there a deadline on a toxic exposure claim?

There is no deadline to file an original claim — a Vietnam veteran can file for the first time this year. The deadlines that do exist are about money and about appeals. Filing an intent to file (VA Form 21-0966) locks in an effective date and gives you up to a year to get the actual claim in, and the effective date is what decides how far back the retroactive payment reaches. Once VA issues a decision, you generally have one year from the date on that decision to keep it alive in one of the three review lanes. Miss that year and the decision becomes final — you can still file again, but the effective date usually restarts.

Does a registry exam start a claim, and can I join a registry without a diagnosis?

Yes to the second, no to the first. The VA exposure registries are open to eligible veterans whether or not anything has ever been diagnosed — that is the point of them. You do not need to be sick, enrolled in VA health care, or service-connected. But a registry evaluation is not a claim, it does not start one, and it will not protect an effective date. It gets your exposure history documented by a clinician, gets you a written results letter, and gets you into the notification system. File the claim separately. All ten programs, what each one covers, and the phone numbers to sign up are on the registries page — VET-HOME, VA's exposure team, is at 833-633-8846.

The law

Presumptions, and what they actually cover

A presumption is the difference between proving a case and confirming a fact. Veterans lose money in both directions here: some never test a presumption they qualify for, and others assume a presumption covers a condition it has never covered.

What does "presumptive" actually mean?

It means the law does part of your job for you. Normally service connection needs three legs: a current diagnosis, an in-service event, and a medical link between them. A presumption removes the link requirement — if you have the listed diagnosis and the qualifying service, VA presumes the connection instead of making you prove it. That is all it removes. You still have to have the diagnosis, and it still has to be the diagnosis that is on the list. A presumption is also a floor and not a ceiling: if your condition is not listed, you have lost nothing, because the ordinary direct route under 38 CFR 3.303 is still open.

I was in the Gulf in 1991. Is the PACT Act only for post-9/11 veterans?

No. The PACT Act (Public Law 117-168) covers two service windows, and the older one starts in 1990. Qualifying service is on or after August 2, 1990 in Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, or the United Arab Emirates; or on or after September 11, 2001 in Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, or Yemen — including the airspace above those locations. The same 23 burn pit and particulate matter conditions cover a Desert Storm veteran and an Afghanistan veteran. Aircrew who never set foot on the ground are frequently told they do not qualify. Read the airspace language again.

I served in Korea. Do I get the herbicide presumption?

Only inside the window, and the window is exact: qualifying service in or near the Korean demilitarized zone from September 1, 1967 through August 31, 1971, under 38 CFR 3.307 and 3.309. A Korea-era assignment by itself proves nothing — the dates, the unit, and where that unit actually operated are what decide it. If your service falls outside that window, the herbicide presumption is closed to you but the case is not: Korea handed its veterans solvents, fuels, exhaust, coatings, unvented heaters, asbestos, and radiation pathways, and those are built on the facts. The full breakdown is in the Korean War file.

My condition is not on any presumptive list. What now?

You build it on the facts. This is called direct service connection under 38 CFR 3.303, and it is how most toxic exposure claims outside the lists are won: establish the exposure, establish the diagnosis, and get a medical opinion linking the two. VA now has an additional duty here — when a veteran has a toxic exposure risk activity (TERA) in the record and files for a condition that is not presumptive, the case can require a 38 USC 1168 medical opinion on whether the exposure caused it. That is a door most veterans never hear about, and it is explained on the TERA and ILER page. Also test secondary service connection under 38 CFR 3.310 — a condition caused or aggravated by something you are already rated for.

The exam and the evidence

The C&P exam, your doctor, and the paper that decides it

Claims are rarely lost on the facts of the service. They are lost on a nine-minute examination and a two-sentence opinion. These are the four places to look when a decision reads as though nobody read the file.

The C&P examiner spent nine minutes with me and never asked about the exposure. Can that be challenged?

Yes, and it is one of the strongest arguments available. VA has to provide an adequate examination, not merely an examination. Barr v. Nicholson holds that once VA undertakes to provide an exam it must be adequate. Nieves-Rodriguez v. Peake holds that an opinion is worth only the reasoning behind it, so a bare conclusion carries no weight. Stefl v. Nicholson requires the examiner to actually address the theory you raised. Jones v. Shinseki holds that "cannot be determined without speculation" is not an opinion unless the examiner explains what further information would resolve it. The pushback guide carries all six cases and a twelve-point adequacy checklist you can run against your own exam report.

My VA doctor says he cannot say whether it is from service. Does that sink the claim?

No. A treating clinician is not required to write your nexus opinion, and many will not — it is outside what they consider their lane, and some are uncomfortable putting a causation statement in writing. What you need from your doctor is different and much more achievable: a clear diagnosis, an accurate exposure history recorded in the chart, and honest documentation of severity and frequency. That is the raw material. The causation opinion can come from a different qualified clinician later. What actually damages a file is when the record contains no exposure history at all, because a later examiner then reads a chart that looks like nothing ever happened. The talk to your doctor page scripts the whole conversation.

What is ILER, and why does VA keep referring to it?

The Individual Longitudinal Exposure Record is the Department of Defense and VA system that stores deployment and occupational exposure data for a service member. VA raters consult it, and it is increasingly what a decision quietly turns on. Two things matter: it is incomplete for a great many veterans, particularly for service before the systems existed and for duty that was never coded, and a blank ILER is routinely treated as though it were proof that nothing happened. It is not proof of anything. If your record is thin, that is an argument you make affirmatively, with unit histories and statements, rather than something you leave for the rater to interpret. Read TERA and ILER.

How do I prove where I was when nobody has the orders anymore?

With everything else. Buddy statements from people who were there, your own detailed statement, unit histories and command chronologies from the service historical centers, deck logs and aircraft maintenance records, personnel evaluations that describe the duty, pay records showing hazardous duty or a combat zone tax exclusion, and photographs with recognizable terrain or equipment. Orders are the cleanest proof but they are one of many, and their absence is not fatal. Build the file in one place first: the exposure sheet is a printable worksheet that walks the whole history out of memory and onto paper before anything is submitted.

Percentages and money

Ratings, reductions, and the math VA never shows you

The percentage is where veterans are quietly shortchanged, because the arithmetic is not the arithmetic anybody expects and the protections are never explained in the decision letter.

Why is 50 percent plus 30 percent not 80 percent?

Because VA does not add. Under 38 CFR 4.25 it uses the whole person method: you start at 100 percent efficiency, the largest rating takes its share, and every rating after that takes its percentage of what is left, not of the original whole. Fifty percent of 100 leaves 50 efficient; 30 percent of that remaining 50 is 15 more, for 65, which rounds to 70 percent. Paired limbs get an extra step — under 38 CFR 4.26 the bilateral factor combines both sides first and then adds 10 percent of that subtotal before the rest is combined. The rating calculator now shows the entire derivation line by line so you can see exactly where every point came from.

If I file for something new, can VA cut a rating I already have?

A new claim does not automatically reopen an old rating, and there are hard protections in the regulations. An evaluation continuously in place for twenty years cannot be reduced below that level absent fraud — 38 CFR 3.951(b). Service connection in place for ten years cannot be severed absent fraud — 38 USC 1159 and 38 CFR 3.957. A rating at the same level for five years is treated as stabilized and takes a higher showing to disturb. What genuinely creates risk is an unprepared re-examination on a condition that has actually improved, and that is a manageable risk rather than a reason not to file. The whole framework is on the rating protection page.

I was denied years ago. Which appeal lane do I use?

There are three, and picking the wrong one is how veterans burn two years. A Supplemental Claim (VA Form 20-0995) is for when you have new and relevant evidence — this is the correct lane for most toxic exposure denials, because the fix is almost always evidence. A Higher-Level Review (VA Form 20-0996) is for when the evidence was already sufficient and VA got the law or the facts wrong; no new evidence is allowed in this lane. A Board appeal (VA Form 10182) goes to a Veterans Law Judge and is the slowest. Generally you have one year from the decision date. All four routes, including what happens after the Board, are laid out on the appeal options page.

Do I have to reach 100 percent to be paid at the 100 percent rate?

No. Total disability based on individual unemployability (TDIU) pays at the 100 percent rate when service-connected disabilities prevent substantially gainful employment, even though the combined schedular rating is lower. Respiratory and neurological damage from toxic exposure is exactly the kind of disability that ends a working life well before the schedule reaches 100. The other thing veterans leave on the table is secondary conditions under 38 CFR 3.310 — sleep apnea, depression, and gastrointestinal disease that arise out of an already service-connected disability are separate ratings, and unclaimed secondaries are usually where the missing percentage is sitting.

The people who were there with you

Your family, and what this site costs

The exposure did not stop at the gate or at the end of the enlistment. Spouses and children lived in the housing, drank the water, and washed the uniforms, and there are programs written specifically for them.

My kids have health problems. Does any of this reach them?

Sometimes, and the pathways are narrow but real. VA recognizes spina bifida in the biological children of veterans with qualifying herbicide exposure, and a broader list of covered birth defects in the biological children of women who served in Vietnam. There is also take-home exposure: fibers and residues carried into a house on a uniform, in a vehicle, and on skin, which is a documented pathway for asbestos and for heavy metals. And separately from anything service-connected, the Camp Lejeune Family Member Program reimburses out-of-pocket medical costs for family members who lived on that base inside the contamination window. Start at the family page and the registries page.

My spouse and I lived in base housing. Can she file anything?

For Camp Lejeune or MCAS New River between August 1, 1953 and December 31, 1987, yes — a family member who resided there for no less than 30 days, cumulative, inside that window can apply to the Camp Lejeune Family Member Program using VA Form 10-10068, and it covers fifteen conditions. Cumulative means it does not have to be consecutive. There is also a separate Marine Corps notification database for anyone who lived or worked there. For contaminated installations other than Lejeune there is generally no family compensation program, but documenting the residence still matters, because it corroborates the veteran's own exposure history.

My husband died. Is there still a claim?

Yes, and there are two of them. A surviving spouse, child, or dependent parent may be entitled to Dependency and Indemnity Compensation when a service-connected condition caused or contributed to the death — and a presumptive exposure condition listed on a death certificate is a direct route to that. Separately, a claim the veteran had already filed does not simply die with him: accrued benefits and substitution allow a survivor to step into the pending claim and finish it. Deadlines apply to substitution, so this is time-sensitive. Everything is on the survivors page and the filing guide.

Do I have to hire anyone to use this site?

No. Everything on this site is free to read, print, and use, and there is nothing gated behind a form. There are two separate doors here and they are both free. Ask a question gets a written answer from an accredited agent with no relationship created and no obligation. Register with us is the hire path — you appoint Albert Thombs on VA Form 21-22a and he works the case for you. Plenty of veterans read the files, build their own exposure sheet, and file it themselves. That is a good outcome, and it is the reason the material is here.
