Why VA Disability Claims Get Denied (and How to Fix It)

Last updated: September 2026
Getting a denial letter from VA stings. You gathered your records, sat through your exam, and waited months, only to read that your claim wasn't approved. I know that feeling personally. It took me over two years to get my own sleep apnea claim service-connected.

A denial isn't the end of the road. Most denials come down to a few fixable problems: a missing diagnosis, a gap in your service records, a weak medical link, a flawed exam, or not enough evidence of how severe your condition is. This post walks through each one, explains what VA is actually looking for, and shows you how to choose the right next step.

Start by Reading Your Decision Letter Closely

Before you do anything else, sit down with your decision letter and read every page. It tells you exactly why VA decided the way it did, and that is your roadmap for fixing it.

Look for three things. First, find the reason for each denial. VA will say whether it didn't find a current diagnosis, an in-service event, or a medical link. Second, look for a section called "favorable findings." These are facts VA already agreed with, such as confirming that you have a current diagnosis. Under VA's rules, those findings generally carry forward to future reviews, so you don't have to prove them again. Third, check the list of evidence VA reviewed. If a record you sent isn't listed, VA may not have considered it.

Also make sure you know the difference between a denial and a 0% rating. A 0% rating means VA agreed your condition is service-connected but not severe enough to pay compensation right now. That's a win you can build on, not a denial.

Reason 1: No Current Diagnosis

VA can't grant service connection for something that hasn't been diagnosed, so this is often the first place a claim falls apart. If your last medical note about your knee is from 2012, VA may decide you don't have a current disability.

The fix is simple, even if it takes time: get seen by a doctor, get a diagnosis, and submit the records. Recent medical records carry much more weight than old ones.

There's one nuance worth knowing. In a 2018 case called Saunders v. Wilkie, a federal court held that pain alone can count as a disability if it causes real functional loss, even without a specific diagnosis. That doesn't mean you should skip getting a diagnosis. It just means "no diagnosis" isn't always the end of the story.

Some conditions need a specific test before VA will accept the diagnosis. Sleep apnea is the clearest example. VA wants to see a sleep study, not just your report of poor sleep. Arthritis generally needs to be confirmed by X-ray. If your condition has a required test, make sure it's in your file.

Reason 2: No In-Service Event on Record

VA also needs evidence that something happened during your service, like an injury, an illness, or an exposure. Many veterans get denied here because they never went to sick call. Plenty of us toughed it out, especially when we were young.

If your service treatment records don't show the event, you still have options. VA must consider lay evidence, which means statements from you and people who saw what happened or saw how you changed. A buddy who was there when you hurt your back, or a spouse who noticed your hearing got worse after a deployment, can fill that gap. Use VA Form 21-10210 for these statements. Other records can help too, such as performance reports, duty assignments, deployment orders, or letters home.

PTSD claims have their own rules about proving the in-service stressor. If your PTSD is related to combat, or to fear of hostile military or terrorist activity, VA can often accept your own statement when a VA psychologist or psychiatrist confirms the diagnosis. For military sexual trauma, VA accepts other types of evidence, like changes in behavior, requests for transfer, or records from outside the military, because these events often weren't reported. The diagnosis itself can come from a VA exam. You don't have to arrive with a stack of private psychological testing.

Reason 3: No Medical Link (Nexus)

This is the most common reason I see claims fall apart. Even with a diagnosis and an in-service event, VA needs a medical opinion connecting the two. That opinion is called a nexus.

Usually, the C&P examiner writes this opinion. If the examiner says your condition is "less likely than not" related to service, VA will probably deny the claim. The standard VA uses is "at least as likely as not," which means a 50% chance or better. When the evidence is evenly balanced, the law says VA must give you the benefit of the doubt.

You can answer a negative opinion with a stronger one. A private doctor can write a nexus letter explaining why your condition is at least as likely as not related to your service. The best letters show the doctor reviewed your records, explain the medical reasoning, and cite research when it helps. A one-line letter that just says "related to service" rarely changes anything.

Don't overlook other paths to service connection either. A secondary condition is caused or worsened by one that's already service-connected, like back pain from years of favoring a bad knee. Aggravation covers a condition you had before service that got worse because of service. Sometimes a claim that fails as a direct claim succeeds on one of these paths.

Reason 4: A Problem With the C&P Exam

Missing your C&P exam without a good reason can lead to a denial on its own. If you can't make it, call right away to reschedule. If you missed one and it led to a denial, you can often fix it by showing good cause and asking for a new exam.

Sometimes the problem is the exam itself. An exam can be inadequate if the examiner didn't review your records, ignored your lay statements, used the wrong diagnosis, or gave an opinion with no reasoning behind it. Some conditions also have strict testing rules. For example, VA hearing exams must be done by a state-licensed audiologist and include both a speech recognition test (the Maryland CNC) and a puretone hearing test. That's one reason a private hearing test often isn't enough on its own.

When VA relies on an inadequate exam, or fails to get records it knew about, that can be a "duty to assist" error. VA has a legal duty to help you develop your claim. In my own case, it took three denials and a Higher-Level Review before VA found a duty to assist error in my sleep apnea claim. If you want to see exactly what the examiner wrote, request your C-file. Mine took about eight months to arrive, so request yours early.

Reason 5: Not Enough Evidence of Severity

Sometimes VA grants service connection but gives you a lower rating than you expected. That usually means VA didn't have enough evidence of how the condition affects your life.

VA rates conditions using the VA Schedule for Rating Disabilities. Each condition has specific criteria. Back conditions, for example, are mostly rated on range of motion and flare-ups, not on what an MRI shows. Imaging can help confirm a diagnosis, but it won't raise your rating on its own. Look up the criteria for your condition so you know what evidence matters.

Tell your full story. Describe your flare-ups: how often they happen, how long they last, and what you can't do during them. Explain missed work, sleep problems, and medication side effects. If medication helps, say so, and also describe what your symptoms are like when it wears off. Under current case law, VA generally can't lower your rating just because medication helps, unless the rating criteria for your condition specifically mention medication. A symptom journal kept over several weeks is some of the most useful evidence you can give an examiner.

Reason 6: Paperwork and Deadline Problems

Simple mistakes can slow a claim down or leave it weaker than it should be. You don't need to know VA's diagnostic codes or use any special wording. VA is supposed to read your claim fairly and consider any condition your evidence reasonably supports. But clear, complete paperwork makes that much easier. Watch for these common problems:

• Filing without an intent to file. An intent to file gives you a year to finish your claim and can protect your back pay. Skipping it can cost you months of benefits.

• Leaving out conditions. List every condition you believe is related to service. You can add more later, but a new claim usually means a later effective date for that condition.

• Missing or mismatched details. Wrong service dates or symptom descriptions that don't match your records can create doubt. Be truthful and consistent everywhere.

• Ignoring VA letters. When VA asks for more evidence, respond quickly. VA may decide your claim before the full response period ends.

• Missing the one-year window after a decision. Filing a review within one year of your decision letter protects your effective date.

A Common Myth About Presumptive Conditions

Presumptive conditions are ones VA assumes are connected to service if you served in certain places or times. The PACT Act greatly expanded these for burn pits, Agent Orange, and other toxic exposures. There's generally no deadline to file a PACT Act claim.

You may have seen warnings that Gulf War veterans must file by December 31, 2026, for undiagnosed illnesses like chronic fatigue syndrome, fibromyalgia, or IBS. That date comes from VA's older regulation. The PACT Act changed the underlying law in 2022, so a qualifying condition can now become manifest to any degree at any time. The law also added Afghanistan, Israel, Egypt, Turkey, Syria, and Jordan to the list of covered locations. VA's regulation hasn't caught up yet. Still, if you have symptoms, don't wait. Filing sooner means an earlier effective date and more back pay.

Keep in mind that presumptive doesn't mean automatic. You still need proof of qualifying service and a current condition, and your claim can still be denied if VA can't confirm either one.

Your Options After a Denial

Under the Appeals Modernization Act, you have three ways to ask VA to take another look. Pick the one that fits your problem:

Option	Best When	Can You Add New Evidence?	Form
Supplemental Claim	You have new and relevant evidence, like a new diagnosis, nexus letter, or buddy statement	Yes	VA Form 20-0995
Higher-Level Review	VA had the right evidence but made a mistake, such as a duty to assist error	No	VA Form 20-0996
Board Appeal	You want a Veterans Law Judge to review your case, with or without a hearing	Depends on the option you choose	VA Form 10182

For Higher-Level Reviews and Board Appeals, you generally have one year from the date of your decision letter to file. You can file a Supplemental Claim at any time, but filing within that year protects your original effective date. VA's decision reviews page has details on each path.

Match the option to the reason for your denial. If VA denied your claim for no medical link, a Higher-Level Review usually won't help unless VA made an error, because the reviewer can't consider new evidence. A new nexus letter through a Supplemental Claim is often the better move. If VA ignored evidence it already had, or relied on a flawed exam, a Higher-Level Review may fix it faster. For Higher-Level Reviews, you can also request an informal conference to point the reviewer to the error.

My own sleep apnea claim is a good example of why persistence matters. In my case, I had to fight for sleep apnea to be considered a service connected disability for over two years, through three denials and a higher level review that found a duty to assist error on the part of the VA. Each denial taught me something about what VA needed to see.

Getting Help With a Denial

Denials are a good time to bring in help. VSOs like the American Legion, VFW, and DAV have accredited representatives who help with reviews and appeals at no cost. A VSO is often my first suggestion to clients.

At this stage, accredited attorneys and claims agents are also an option. Under VA's fee rules, they can charge fees after VA makes an initial decision, usually a percentage of any back pay they help you win. That can be worth it for complex cases or Board appeals. Before you sign anything, confirm the person is VA-accredited. Be cautious of companies that aren't accredited but promise higher ratings for a fee.

Conclusion

Getting your VA disability claim denied doesn't mean you don't deserve benefits.A denial usually means something was missing, not that you don't deserve benefits. Read your decision letter, figure out which piece VA said was missing, and choose the review option that addresses it. Watch the one-year window so you protect your effective date.
