VA Disability Claims & Military Separation Guide
A step-by-step guide to documenting injuries, filing claims, and maximizing veteran benefits — written for someone who has never dealt with the VA before.
Why this matters
If you're separating from the military, especially after a deployment or combat tour, there's a good chance you're carrying injuries or conditions you haven't fully dealt with. This section explains why documenting them now — even if they seem minor — protects you for decades.
Why filing matters
VA disability compensation isn't a handout. It's compensation for things service did to your body and mind, paid out for as long as the condition affects you — which, for many conditions, is for life. Filing a claim is how you formally connect a current health problem to your time in service so the VA can evaluate and pay for it.
Why documentation is everything
The VA can only approve what it can verify. A condition you know is real but never wrote down anywhere is, from the VA's perspective, a condition that doesn't exist yet. Documentation — medical records, service records, statements from people who knew you — is what turns "I have headaches all the time" into a recognized, compensated disability.
Why veterans underreport
Military culture rewards pushing through pain and discomfort. Many service members spend years minimizing symptoms to stay deployable, avoid being seen as weak, or just because that's what was modeled around them. That habit doesn't serve you anymore once you're filing a claim — a C&P examiner can only rate what you actually describe (more in Section 8).
Why so many veterans wish they'd filed sooner
A common pattern: a veteran waits years after separation, the condition has worsened, records have gone missing or are harder to retrieve, memories of specific incidents have faded, and witnesses have scattered. None of that makes a claim impossible, but all of it makes it harder. Filing earlier — even an initial Intent to File, covered in Section 3 — keeps your options open while you gather the rest.
You don't need a perfect case to start. You need to start. Conditions can be added later, evidence can be supplemented, and decisions can be appealed. What you can't get back is time — many forms of compensation are paid back to the date you first signaled your intent to claim, not the date you finished gathering paperwork.
The VA claims process, start to finish
Every claim — simple or complicated — moves through the same seven stages. Knowing what's coming makes each stage less stressful and helps you spot when something is taking unusually long.
Identify your conditions
List every physical and mental health issue connected to your service, no matter how minor it seems. This includes things that started in service and things that got worse because of service.
Gather evidence
Medical records, service records, statements from people who served with you. You don't need everything before filing — see Section 3 on why filing an Intent to File early still makes sense.
Submit an Intent to File
This locks in your effective date for up to one year, so any later approved claim can pay back to this date instead of the date you finish your paperwork. Covered in depth in Section 3.
File your claim
Submit VA Form 21-526EZ online, by mail, in person, or with help from a VSO — with whatever evidence you currently have.
Attend C&P exam(s)
A Compensation & Pension exam where an examiner evaluates your condition. Not every claim requires one. See Section 8 for how to prepare.
Receive a decision
The VA issues a rating decision: approved (with a percentage), denied, or deferred pending more information.
Appeal if necessary
A denial or a rating you disagree with isn't the end of the road. Section 16 walks through Supplemental Claims, Higher-Level Review, and Board Appeals.
The power of the Intent to File
If this site could make you remember only one thing, it would be this: submit an Intent to File today, even if your evidence isn't ready. It costs nothing and can be worth thousands of dollars in back pay.
What it actually is
An Intent to File (VA Form 21-0966) is a short, simple notice to the VA that says "I plan to file a disability claim." It is not the claim itself — it's a placeholder that buys you time.
Why it preserves your effective date
The VA generally pays retroactive benefits back to your "effective date" — and filing an Intent to File sets that date the moment you submit it, rather than the date you eventually finish your full claim. You then have up to one year to submit the complete claim while keeping that earlier date.
Say you submit an Intent to File on day one, then spend four months gathering medical records and a nexus letter before filing the full claim. If the VA approves the claim, back pay is generally calculated from your Intent to File date — not from the day you finally hit submit on the full claim four months later. Without the Intent to File, those four months of potential back pay are simply gone.
When to submit it
As soon as you know you have a condition you intend to claim — even before you have a diagnosis, even before you've left the military, even if you're not sure which conditions you'll ultimately include. You can submit one today in a few minutes on VA.gov.
Common mistakes
- Waiting until the claim package is "ready." The entire point of the Intent to File is that you don't have to be ready.
- Letting it expire. You have one year from the Intent to File date to submit the actual claim. If that year passes without a claim, the Intent to File expires and you'd need to submit a new one — losing the original date.
- Assuming it's the same as filing. It is not a claim and will not result in a decision or payment on its own. You still have to file the full claim.
- Not realizing you can add conditions later. One Intent to File can cover multiple conditions you haven't fully identified yet.
There is essentially no downside to submitting one today. The only mistake is not doing it.
The Evidence Blueprint: what wins claims
Almost every successful VA claim rests on the same three legs. Understand these and you understand what the VA is actually looking for, no matter what condition you're claiming.
Current diagnosis
Proof you have the condition right now.
- Medical diagnosis on record
- Civilian doctor visit
- VA provider evaluation
- Specialist evaluation
In-service event or exposure
Proof something happened during service that could cause it.
- Service Treatment Records
- Deployment orders
- Combat operations record
- Incident or exposure reports
- Awards, personnel records
- Performance evaluations
Nexus (the connection)
Proof the service event actually caused the current diagnosis.
- Medical nexus letter
- Doctor's stated opinion linking service to diagnosis
- Secondary condition reasoning (one condition causing another)
Why all three matter together
Having a diagnosis alone tells the VA you're sick, not that the military made you sick. Having a service event alone tells the VA something happened, not that it's still affecting you today. The nexus is the bridge between the two — and it's the piece veterans most often leave out.

Claim Strength Meter
No evidence selectedSpecial situations: war zones and combat operations
If you separated out of a deployment, especially a combat tour, your situation has unique evidence challenges — and unique options the VA built specifically for it.
The reality on the ground
In combat zones, medical care is triaged for survival, not documentation. Hospitals may have been destroyed, overwhelmed, or simply unavailable. Operational tempo can make it impossible to seek treatment for anything short of an emergency. Many service members pushed through injuries because stopping wasn't an option.
A lack of medical records does NOT automatically mean a claim fails. The VA recognizes that combat conditions make contemporaneous documentation difficult or impossible, and there are established ways to build a case without a paper trail from the moment of injury.
What can stand in for missing medical records
- Buddy statements — written accounts from people who witnessed the event or your symptoms afterward (builder in Section 12)
- Personal journals or diaries from the time
- Photos showing injuries, conditions, or circumstances
- Emails or letters home mentioning symptoms or incidents
- Deployment records placing you at a specific place and time
- Awards and citations that reference the incident (e.g., a Purple Heart citation)
- Witness statements from supervisors or fellow service members
- Command logs or unit records
- Geotagged photos or location data, where available
- Exposure documentation, such as burn pit registry entries or unit deployment to a recognized exposure location
Combat presumptions
For combat veterans specifically, the law allows lay evidence (your own statement and statements from others) to establish that an event happened in service, even without official records — as long as the evidence is consistent with the circumstances of your service. This is sometimes called the "combat presumption" and it exists specifically because the VA recognizes record-keeping breaks down in combat.
How to file a claim
You have three main paths to actually submit a claim. None is universally "best" — it depends on your comfort with technology, how complex your claim is, and whether you want help.
Online filing (VA.gov)
File directly through your VA.gov account using Form 21-526EZ, uploading evidence as digital files (PDFs or photos of documents).
| Pros | Cons |
|---|---|
| Fastest submission, available 24/7 | No human to ask questions in the moment |
| Immediate confirmation of receipt | Requires comfort navigating a government website |
| Easy to track status afterward | Easy to miss something without a second set of eyes |
In-person filing
File at a VA regional office, with help from a Veterans Service Officer (VSO) at a Veteran center, or at certain county/state veteran affairs offices.
| Pros | Cons |
|---|---|
| Free, expert help from someone who reviews your full case | Requires scheduling and travel |
| Mistakes get caught before submission | Wait times for appointments vary by location |
| Someone to ask questions specific to your case | Less convenient if you're not near an office |
Virtual filing assistance
Many VSOs and some VA staff now offer telehealth-style remote consultations, reviewing your documents digitally without an in-person visit.
| Pros | Cons |
|---|---|
| Combines expert help with at-home convenience | Still depends on availability of the VSO/representative |
| Good for rural veterans far from an office | Document handling can be clunkier than in-person |
Types of claims
"Filing a claim" isn't one single thing. The VA recognizes several distinct claim types, and picking the right one for your situation affects both your paperwork and your timeline.
Original claim
Your first-ever disability claim for a given condition. Most veterans start here. There's no minimum evidence requirement to file — you can file with a little evidence or a lot, though more complete evidence generally moves faster.
Increase claim
For a condition the VA already rates, filed when that condition has gotten worse and you believe you qualify for a higher percentage. This requires new medical evidence showing the worsening — your original diagnosis evidence alone won't support an increase.
Secondary condition claim
For a condition caused or worsened by an already-service-connected condition, rather than by service directly. For example, a service-connected knee injury that changes your gait and eventually causes hip problems. The nexus here is medical: connecting the secondary condition back to the primary one, not back to service itself.
Supplemental claim
Filed after a denial, when you have new and relevant evidence you didn't submit before. This is different from an appeal in the legal sense — you're not arguing the VA was wrong, you're giving them something new to consider. Covered alongside the other appeal-adjacent paths in Section 16.
Fully Developed Claim (FDC)
Not a separate category so much as a filing method: you submit all your evidence with the claim and certify you have nothing more to add. This can speed up processing because the VA doesn't need to spend time requesting additional records — but only choose this if you're genuinely confident your evidence package is complete.
If you've never claimed a condition before: original claim. If the VA already rates it and it's worse now: increase claim. If a service-connected condition caused a new problem: secondary condition claim. If you were already denied and have new evidence: supplemental claim. Many veterans file several of these at different points for different conditions — they're not mutually exclusive across your overall case.
The C&P exam survival guide
For many claims, the Compensation & Pension exam is the single most influential piece of evidence in the whole file. How you handle it matters as much as the medical facts themselves.
What it actually is
A C&P exam is a medical evaluation, performed by a VA provider or a VA-contracted provider, ordered specifically to gather evidence for your claim — it is not the same as a regular doctor's visit and isn't about treating you. The examiner will typically ask about your symptoms, history, and how the condition affects your daily functioning, then document findings (often using a DBQ, covered in Section 9).
It's free. The VA covers the full cost of a C&P exam — you should never be billed for one. It's not the only path to a rating. Some claims are decided on existing medical records alone without an exam being scheduled at all. Neither having one nor not having one automatically helps or hurts your claim by itself — what matters is the quality of evidence either way.
The single most important concept: the "worst day" standard
Describe your symptoms as they are on your worst days, not your average or best days. Veterans who minimize symptoms out of habit (see Section 1) often unintentionally describe a "good day" to the examiner, which can result in a lower rating than their condition actually warrants. This isn't about exaggerating — it's about giving a complete and honest picture instead of an incomplete one.
Do this
- Be specific, not general. "I can't concentrate" is vague. "I can't finish reading a two-page memo without losing my place three or four times" is something an examiner can actually rate.
- Describe functional impact, not just symptoms. Connect the symptom to a real consequence: missed work, strained relationships, activities you've stopped doing entirely.
- Bring a written symptom list. Memory under stress is unreliable for everyone. Having notes ensures you don't forget something important in the moment.
- Answer the question that's actually asked. If you don't understand a question, ask the examiner to clarify rather than guessing.
- Show up and be on time. A missed exam without rescheduling can result in your claim being rated on paper evidence alone or even denied for failure to report.
Avoid this
- Minimizing out of habit. "I'm fine, it's not a big deal" is the single most common way veterans under-describe a real condition.
- Exaggerating. Examiners are trained to notice inconsistency between your self-report and observed behavior, and inflated claims can damage your credibility on conditions that are genuinely real.
- Vague non-answers. "I'm tired" or "I'm stressed" without elaboration gives the examiner very little to work with — be ready to say how, when, and how often.
- Treating it like a casual chat. It's a friendly conversation, but it's also a formal evidence-gathering appointment. Stay focused on your condition.
DBQs explained
Disability Benefits Questionnaires get mentioned constantly in veteran communities, and the chatter often makes them sound more mysterious — or more mandatory — than they actually are.
What a DBQ is
A condition-specific form a licensed healthcare provider fills out to document your diagnosis, symptoms, and how the condition affects daily function, in a structured format the VA can use to assign a rating. There's a different DBQ for nearly every condition category — one for knees, a different one for PTSD, and so on.
Who fills it out
You cannot fill out your own DBQ. It must be completed and signed by a licensed provider — a VA examiner during a C&P exam, or (for some conditions) a private physician you choose yourself.
A DBQ is not required for your claim to succeed. If the VA orders a C&P exam, the examiner will complete one as part of that process automatically — you don't need to bring your own. Submitting a private DBQ in advance can sometimes add useful evidence, but its absence does not doom a claim.
The private DBQ option
For some conditions, you can have your own doctor — someone who already knows your medical history — complete a DBQ on your behalf and submit it with your claim. This can be useful evidence, but you're responsible for any cost of the visit; the VA does not reimburse for a privately completed DBQ.
A practical tip if you go the private route
DBQ forms themselves often don't require the provider to explain their reasoning behind an answer — just check a box or write a brief note. A DBQ that's just checkboxes with no explanation is weaker evidence than one with a short written rationale attached. If you're having a private provider complete one, ask them directly to add a brief explanation supporting their findings, even though the form doesn't require it.
Getting your records: a retrieval guide
Evidence can't help your claim if you can't find it. Here's where the major categories of records actually live, and how to request each one.
Service Treatment Records (STRs)
Your medical records from active duty. If you separated recently, these may already be visible in your VA.gov or DoD health records account. Older records may need to be requested from the National Archives (NARA) in St. Louis, particularly if your service predates full digital recordkeeping.
Electronic military health records
More recent service members' records typically live in the DoD's electronic health record system. You can usually request a download or printed copy directly through the patient portal associated with your branch's health system, or through Tricare Online if you used Tricare during service.
Personnel records
Deployment orders, awards, performance evaluations, and other non-medical personnel records can also be requested through the National Archives or through your branch's personnel records center. These matter most for establishing the "service event" pillar of the Evidence Blueprint (Section 4) — proving where you were and what happened, even when medical documentation is thin.
Civilian medical records
Any treatment you received outside the military — before, during, or after service — from a civilian provider. You'll need to request these directly from each provider or health system; the VA generally won't go looking for these on its own unless you identify the provider and give the VA permission (via a release form) to request them on your behalf.
VA medical records
If you've already been receiving care through the VA health system, those records are typically already accessible to the people processing your claim, but it's still worth confirming they're attached to your specific claim rather than just floating in the general health record system.
| Record type | Where to request it |
|---|---|
| Older / pre-digital STRs | National Archives (NARA), St. Louis |
| Recent electronic health records | Branch health system patient portal / Tricare Online |
| Personnel records, awards, deployment orders | National Archives or branch personnel records center |
| Civilian provider records | Directly from the provider, with a signed release |
| Existing VA treatment records | Usually already accessible — confirm they're linked to your claim |

Buddy statement organizer
A buddy statement is a written account from someone else — a fellow service member, a supervisor, a family member — describing what they witnessed. It carries real weight in a federal claim, which means it only works if it's true and specific. This tool doesn't write the statement for the person providing it. It organizes their own words into a clear, complete structure.
A buddy statement is a sworn account submitted as evidence in a federal benefits claim. The person writing it should only describe what they personally witnessed or experienced, in their own words. This tool helps organize and format that account — it does not generate claims, invent details, or write content on the witness's behalf. Vague prompts answered honestly are far more useful, and far safer, than detailed-sounding answers that aren't accurate.
Fill in what you (the witness) actually know
Leave anything blank that doesn't apply to you. The preview below only includes what you write.

This is your sworn statement in a federal benefits claim. Answer the prompts honestly and specifically, based on your own experience and memory. The tool's job is to help you organize a clear, complete statement out of your own words — not to suggest what you should have experienced or to generate claims for you.

VA disability ratings explained
Every condition the VA approves gets a percentage rating in increments of 10 (0%, 10%, 20%, and so on up to 100%). That percentage drives your monthly compensation. The part that surprises almost everyone: multiple ratings don't simply add together.
Why ratings aren't added together
The VA treats each rating as a percentage of your overall function lost, and assumes some overlap between disabilities rather than treating every condition as taking an independent 100% slice. The result, often called "VA math," works by combining ratings from highest to lowest, where each new rating applies to whatever overall function is left, not to the original whole. This means two 50% ratings combine to 75%, not 100% — and it's the single most misunderstood part of the ratings system.
The short version
Rank your ratings highest to lowest. Apply the highest first. Each next rating applies to what's left over, not the full 100%. The final number rounds to the nearest 10%.
A worked example
50% + 30% + 10% does not equal 90%. It combines to roughly 68.5%, which rounds up to a final combined rating of 70%.
The bilateral factor
If you have compensable ratings affecting both sides of a paired body part — both knees, both shoulders, both legs — federal regulation (38 CFR § 4.26) adds a further 10% of the combined value of those two ratings specifically, before that combined figure is folded in with everything else. This recognizes that a disability affecting both sides of the body tends to impact daily function more than the same disability on one side alone.
Determining exactly which conditions qualify involves specifics (matching diagnostic codes, which body parts are actually "paired") that go beyond what a simple calculator can safely judge for you. The calculator below includes an optional bilateral factor toggle for two ratings you identify as paired — use it only if you're confident those two ratings genuinely qualify, and double-check with a VSO if you're not sure.

|---|---|
| 10% | $180.42 |

| 40% | $796.79 |

| 100% | $3,938.58 |
How long claims actually take
This is one of the fastest-changing numbers in this entire guide, and one of the most-searched. Treat any specific figure — including the one below — as a snapshot, not a promise.
As of the end of May 2026, the VA's published average time to complete a disability claim decision was 78.6 days — down sharply from 141.5 days in January 2025. This reflects a broader, sustained reduction in the VA's claims backlog over roughly the past year and a half.
Why you'll see wildly different numbers elsewhere
Search around and you'll find third-party sites citing anywhere from roughly 75 to 150 days. This isn't necessarily anyone being dishonest — it's a mix of outdated snapshots from earlier months, different claim types being averaged differently, and some sites simply not updating their published number as often as the VA updates its own. The underlying VA average has moved substantially over the past year, so a number that was accurate when an article was written can be stale within a few months.
What actually drives your individual timeline
- Evidence completeness at filing. A Fully Developed Claim (Section 7) with everything attached up front tends to move faster than one the VA has to chase evidence for.
- Number of conditions claimed. More conditions generally means more to evaluate, though not always proportionally longer.
- Whether a C&P exam is needed, and how quickly one can be scheduled in your area.
- Development letters. If the VA has to pause and request something specific from you, your claim's clock effectively waits on your response.
- Claim type. Original claims, supplemental claims, and the different appeal lanes (Section 16) all move at different paces.
If you disagree with a decision
A denial, or a rating lower than you believe is accurate, is not the end of the process. Since 2019, the VA has used a system with three distinct paths forward — called the Appeals Modernization Act, or "AMA" — and picking the right one for your situation matters.
Supplemental Claim
File this when you have new and relevant evidence you didn't submit the first time — something the VA hasn't already seen. This is often the right move when a denial happened because something was missing, and you've since obtained it (a nexus letter, for example, or records that finally came through).
Higher-Level Review
A senior VA reviewer takes a fresh look at the same evidence already in your file, checking for an error in how the original decision was made. No new evidence is added at this stage — this path is specifically for when you believe the decision itself was wrong based on what was already there.
Board Appeal
Your case goes to a Veterans Law Judge at the Board of Veterans' Appeals. This generally takes the longest of the three paths, but it's the right venue for complex disagreements, especially ones likely to need a hearing or extensive legal argument.
| Path | Best when... |
|---|---|
| Supplemental Claim | You have new evidence you didn't submit before |
| Higher-Level Review | You believe the original decision was wrong based on existing evidence |
| Board Appeal | Your case is complex or you want a hearing before a judge |
Your decision letter explains your options and deadlines for your specific case. An accredited VSO (Section 17) can also help you think through which lane fits your situation — this is exactly the kind of decision where a second, experienced opinion is valuable.
Understanding VSOs
A Veterans Service Officer (VSO) is one of the most underused free resources in the entire system. This section explains what they actually do and how to find one.
What a VSO does
An accredited VSO is trained and authorized to help you prepare, file, and track a VA claim — reviewing your evidence, helping you avoid common mistakes, filling out forms correctly, and in many cases representing you if you appeal. Accreditation means they've met specific VA training and conduct requirements; it's a real credential, not an informal title.
It's free
Accredited VSOs cannot charge you for help with an initial claim. This is one of the clearest reasons to use one before considering any paid option (see Section 18 on for-profit "claim sharks" for what to watch out for instead).
Where to find one
- National service organizations — groups like the DAV (Disabled American Veterans), VFW (Veterans of Foreign Wars), and the American Legion all maintain large networks of accredited VSOs, often with offices near VA facilities.
- County and state veteran affairs offices — many counties and states employ their own accredited VSOs, sometimes with the shortest wait times since they're a less-known option.
- VA regional offices — VSOs are often available directly on-site.
What to expect from a good one
A good VSO reviews your full situation, asks clarifying questions, helps you identify conditions you might not have considered claiming, and is upfront about realistic outcomes rather than promising a specific rating. Section 18 covers how to spot the warning signs of a bad one, or of a predatory paid alternative.
Watch out for "claim sharks"
Because accredited VSO help is free, anyone charging you money up front to "help" with an initial disability claim should raise an immediate red flag.
It is illegal for most non-attorney representatives to charge a fee for helping you prepare or file an initial disability claim. Fees can legally apply only after a claim has already been decided once, and only under specific, regulated circumstances (such as representation on an appeal). Anyone asking for money to "get your claim started" is operating outside the rules.
Common red flags
- Upfront fees for a first-time claim. This is the clearest sign something is wrong.
- Guaranteed ratings. No legitimate VSO, attorney, or representative can promise you a specific percentage before the VA has reviewed your case.
- Pressure to sign quickly. Legitimate help doesn't require rushing you into an agreement.
- Asking for a cut of your back pay. Be especially cautious of arrangements that take a percentage of retroactive benefits for help with an original claim.
- Vague credentials. A legitimate representative can be verified through the VA's own accreditation search (mentioned in Section 17) — if someone can't be found there, that's a problem.
What's actually legitimate
Accredited VSOs, claims agents, and attorneys can all be paid in specific, regulated circumstances — typically once a claim reaches the appeals stage. The distinction that matters most for you, right now, while you're filing an original claim: free help is the norm, not the exception, and it's normally just as good or better than paid help because accredited VSOs handle this for a living without a financial incentive to overpromise.
Conditions veterans commonly forget to claim
Some conditions are easy to overlook because they feel like background noise rather than a "real" injury — until you stop and think about how long they've actually been part of your life.
Hearing & ringing
Tinnitus (ringing in the ears) and hearing loss are among the most commonly service-connected conditions, especially after exposure to gunfire, aircraft, or heavy machinery — even without a single specific incident.
Sleep problems
Sleep apnea and chronic insomnia are frequently connected to other service-related conditions (weight changes, PTSD, respiratory issues) even when they weren't diagnosed until years later.
Joint & back pain
Years of rucking, jumping, and carrying heavy loads add up. Many veterans treat ongoing joint or back pain as just a normal part of having served, rather than something to formally claim.
Skin conditions
Chronic skin conditions tied to environmental exposure, certain uniforms or gear, or climate during deployment are often under-claimed simply because they don't feel "serious."
GI & digestive issues
Chronic digestive problems, sometimes connected to stress, deployment diet, or specific exposures, are easy to dismiss as unrelated to service.
Scars
Scars from service-related injuries can be separately ratable, particularly if they're painful, unstable, or cover a significant area — something many veterans don't realize is claimable on its own.
If you find yourself thinking "that's just how it is now" about something physical or mental that started or worsened during your service, that's worth a second look — not necessarily a guaranteed claim, but worth checking against the Evidence Blueprint in Section 4 rather than dismissing automatically.
Mental health claims
PTSD, anxiety, depression, and other mental health conditions are claimed differently in some ways than physical conditions, mostly around how the "service event" is verified.
The same Evidence Blueprint applies
You still need a diagnosis, a connection to service, and (where applicable) a nexus — the three pillars from Section 4 don't change. What's different is how the "service event" piece — sometimes called a stressor for PTSD specifically — gets verified.
Stressor verification
For PTSD claims tied to a specific traumatic event, the VA generally wants some evidence the event occurred. For combat-related stressors, the combat presumption discussed in Section 5 can reduce this burden significantly — your own credible statement, consistent with your service record, can be enough. For non-combat stressors (training accidents, military sexual trauma, other in-service trauma), the verification standard is more case-specific, and a personal statement (Section 13) describing what happened in as much detail as you're able to provide is often central to the claim.
Special evidence note for military sexual trauma (MST)
The VA recognizes that MST is frequently underreported at the time and rarely has the kind of official documentation other in-service events might. Markers like changes in performance evaluations, requests for transfer, unexplained absences, or behavioral health visits around the time of the event can serve as supporting evidence even without a formal report on record. This is a sensitive and case-specific area where a VSO experienced in MST claims, or a Veterans Affairs PTSD or MST coordinator, can be especially valuable.
The C&P exam for mental health conditions
Everything from Section 8 applies, with extra emphasis on describing functional impact concretely: not just "I have anxiety" but how it actually shows up — avoided situations, strained relationships, work problems, sleep disruption. The "worst day" standard matters especially here, since mental health symptoms often fluctuate significantly.
The PACT Act: what it changed
Signed into law in 2022, the PACT Act is the largest expansion of VA benefits for toxic exposure in decades. Here's the shape of what it does — for the current, complete list of covered conditions, you'll want VA.gov directly, since this list has continued to expand since enactment.
What "presumptive" actually means
Normally, you have to show a nexus connecting your condition to service (Section 4). A presumptive condition skips that step for veterans who meet specific service and location criteria — if you served in a qualifying place and time, and you have one of the recognized conditions, the VA presumes the connection rather than requiring you to prove it. This removes the single hardest part of many toxic exposure claims.
The major exposure categories the PACT Act covers
- Burn pits and other airborne hazards — for veterans who served in qualifying locations and time periods, primarily tied to Iraq, Afghanistan, and other post-9/11 deployments.
- Agent Orange — expanded locations and presumptive conditions beyond the original Vietnam-era list, including additional sites in Thailand, Laos, Cambodia, Guam, and American Samoa.
- Gulf War-era exposures — expanded presumptive periods and locations for veterans of the 1990s Gulf War and related operations.
- Radiation exposure — expanded locations recognized for radiation-related presumptive conditions.
- Camp Lejeune water contamination — for veterans, reservists, and family members who were stationed at Camp Lejeune during the qualifying contamination period.
The presumptive conditions list has been updated multiple times since 2022 and continues to change — different sources online cite different totals, and a number that's accurate today may not be in a few months. Rather than risk giving you a stale or incomplete list, check the official, continuously updated list directly at va.gov/resources/the-pact-act-and-your-va-benefits.
What to actually do with this
If you served in a location or time period connected to any of the categories above, check the current presumptive list before assuming a condition needs the full nexus treatment from Section 4. Even if your specific condition isn't (yet) on the presumptive list, you can still file a standard claim using the regular evidence path — presumptive status makes a claim easier, but its absence doesn't make a claim impossible.
Filing before you separate: BDD claims
If you're still on active duty and know your separation date, you may be able to file your disability claim before you even leave the military — and get a decision shortly after.
What BDD is
The Benefits Delivery at Discharge (BDD) program lets you file a claim while still on active duty, between 180 and 90 days before your separation date. This window gives the VA time to review your records and schedule any needed exams before you separate, with a goal of delivering a decision soon after your actual discharge date.
Eligibility requirements
- You must know your separation date and file within the 180-to-90-day window before it.
- You need to provide your Service Treatment Records (or consent to their release) with the claim.
- You generally need to complete the Separation Health Assessment self-assessment as part of the package.
- You must be available for VA exams for a period after filing (commonly around 45 days), since exams typically need to happen before you separate.
Who BDD generally doesn't fit
Service members who are seriously ill or injured, terminally ill, awaiting a medical discharge determination, or who have lost a body part are typically excluded from standard BDD processing — these situations usually go through a different, more specialized track. If you're inside the 90-day window and missed it, you can still file as a standard claim immediately after separating; you haven't lost the ability to claim, just the BDD-specific fast lane.
BDD doesn't just save time after you separate — it means your claim, exams, and evidence-gathering happen while you still have easy access to your unit, your records, and people who can write buddy statements (Section 12) if needed, all while you're still in a familiar system rather than navigating it for the first time as a brand-new veteran.
Advanced topics: secondary connection, aggravation, TDIU, and SMC
Once you understand the basics, a few more advanced mechanisms can meaningfully change your overall outcome. None of these are starting points — they build on everything covered so far.
Secondary service connection
Already covered briefly in Section 7: a condition caused or made worse by a condition that's already service-connected. The nexus here connects condition to condition, not condition to service directly. Common examples include a knee or hip problem caused by an altered gait from a service-connected foot or leg injury, or sleep apnea connected to a service-connected mental health condition or weight change.
Aggravation
If you had a condition before service that military service made measurably worse, you may be able to claim the degree of worsening — not the original baseline condition, but the additional impairment service caused. This requires evidence of your condition's severity before service (to establish the baseline) and evidence of its severity now, so the VA can isolate what changed.
TDIU: Total Disability based on Individual Unemployability
TDIU lets the VA pay you at the full 100% rate even if your combined schedular rating is below 100%, when your service-connected conditions prevent you from holding substantially gainful employment. There are two paths:
- Schedular TDIU — you qualify automatically for consideration if you have one condition rated at 60% or higher, or two or more conditions combining to 70% or higher with at least one of those individually rated at 40% or higher.
- Extraschedular TDIU — for veterans who don't meet those specific percentage thresholds but can still show, through the totality of their circumstances, that their service-connected conditions prevent substantially gainful employment. This path requires additional review and is generally harder to establish.
"Substantially gainful" employment is generally judged against the federal poverty threshold for one person — earning below that level (or working in a specially accommodated or family-protected environment) doesn't disqualify you the way a normal job would.
SMC: Special Monthly Compensation
SMC is an additional benefit, paid on top of or sometimes instead of standard compensation, for especially severe circumstances: loss of use of a limb or organ, blindness, being housebound, or needing daily Aid and Attendance from another person for basic activities like eating, bathing, and dressing. It has multiple lettered categories with different criteria and payment levels, and the specifics are detailed enough that this guide won't attempt to reproduce the full table.
Military separation checklist
Beyond the disability claim itself, leaving the military involves its own administrative checklist. This one's broader than just VA claims — it covers the paperwork and decisions that are much easier to handle while you're still in than after you've separated.
Frequently asked questions
Quick answers to the questions that come up constantly. Click any question to expand it.
Yes — you can file an Intent to File (Section 3) before you have a diagnosis. For the full claim itself, you'll generally want a diagnosis in hand, but the VA can sometimes order a C&P exam that results in one as part of the process, especially for presumptive conditions (Section 21).
VA disability claims and ratings are handled separately from security clearance investigations, and having a disability rating, including for mental health conditions, is not by itself a disqualifying factor. If you have specific concerns tied to a particular clearance level or employer, that's worth a direct conversation with a VSO or your clearance-granting authority rather than guessing.
Yes. You can file additional original claims for new conditions at any time, regardless of whether your earlier claims are still pending or already decided. Each condition is generally evaluated on its own evidence and timeline.
No — a low rating still means the condition is officially service-connected, which matters for future increase claims (Section 7) and for any related secondary conditions down the line. It also means you have a paper trail that didn't exist before. If you believe the rating itself is too low for your actual symptoms, Section 16 covers your options to challenge it.
Yes, and this is extremely common. If you have new and relevant evidence you didn't have before — a nexus letter, new medical records, even an updated understanding of presumptive conditions (Section 21) that didn't exist at the time — you can file a Supplemental Claim (Section 16) regardless of how long ago the original denial happened.
No. The vast majority of veterans file successfully with help from a free accredited VSO (Section 17) or no outside help at all. Attorneys generally become relevant at the appeals stage (Section 16) for complex or contested cases, not for an original claim.
What veterans wish they'd known earlier
Patterns that show up again and again in veteran communities, distilled down to the lessons themselves rather than any single story.
- → File the Intent to File the same day you start thinking about it. Nobody ever regrets filing one too early. Plenty of veterans regret waiting.
- → Minor conditions are still conditions. The thing you've decided isn't "bad enough" to claim is exactly the thing most veterans wish they'd claimed while it was still well-documented and fresh.
- → Describe the worst day, every time. This single habit shift, in C&P exams and in personal statements, changes outcomes more than almost anything else in this guide.
- → A denial isn't the end. Supplemental claims, Higher-Level Review, and Board Appeals all exist because the VA itself recognizes decisions aren't always right the first time.
- → Free help is real help. An accredited VSO costs nothing and generally knows more about the current process than any single guide, including this one, can stay perfectly current on.
- → Documentation now is easier than documentation later. Records get harder to retrieve, memories fade, and witnesses scatter. The best time to gather evidence was during service. The second-best time is today.

Don't forget state-level benefits
Everything in this guide so far is federal. Most states also offer their own veteran benefits — property tax exemptions, education benefits, hiring preferences, and more — that exist entirely separately from anything the VA decides.
State veteran benefits vary enormously and change independently of federal rules, often tied to your state of legal residence rather than where you served. A national guide trying to track 50 different and frequently-updated benefit systems would go stale almost immediately and risk giving you confidently wrong information about your specific state.
Where to actually check
Search "[your state] department of veterans affairs" or "[your state] veteran benefits" directly, or ask the VSO you're already working with (Section 17) — county and state VSOs in particular often handle state-level benefits applications alongside federal claims, since they're frequently the same office.
Before you move on: the one thing to remember
This guide has covered a lot of ground. If you forget the specifics of any one section, hold onto this:
File an Intent to File today. Document everything, even what feels minor. Describe your worst days honestly, every time you're asked. Use free help (a VSO) before paid help. A denial is a data point, not a final answer. None of this requires you to have it all figured out before you start — it only requires that you start.
The next and final section turns all of this into a concrete first-90-days plan, with its own version of the Claim Strength Meter from Section 4 so you can check your progress as you go.
Your first 90 days: a roadmap
Everything in this guide, organized into a three-phase plan. Use this as your home base — every checklist item links back to the section that explains it in full.
Phase 1: Days 1–30 — Stabilize and organize
Phase 2: Days 31–60 — Build your claims package
Phase 3: Days 61–90 — File and prepare for what's next
One more check: your Claim Strength Meter
Before you file, run through the strength meter one more time for whichever condition feels least certain to you.
