Before You File
Things Veterans Should Know Before Filing Their VA Claim
Most problems in a VA claim are set in motion before the claim is ever filed. Veterans file for the wrong thing, file before they have the evidence, or expect a part of the system to do a job it was never designed to do.
None of these mistakes are about gaming the system. They're about understanding how it works so the claim you file is the claim you meant to file. Here are the ones we see most.
1. A C&P exam will not diagnose you, and it isn't supposed to
This is the most common misunderstanding in the entire process. Many veterans file a claim for symptoms they've never had evaluated, expecting the Compensation and Pension (C&P) exam to figure out what's wrong. Then they're surprised when a 40-minute appointment doesn't produce an answer.
The two systems have different jobs:
| Health care | The VA compensation system |
|---|---|
| Investigates symptoms, runs tests, and diagnoses conditions | Confirms that a diagnosis exists |
| Treats you over time | Measures how severe the condition is against the rating schedule |
| Documents your history visit by visit | Provides a medical opinion on whether the condition is connected to service |
A C&P examiner completes a Disability Benefits Questionnaire built around the rating criteria. The appointment is structured to answer VA's questions, not to work up an unexplained problem. Examiners can and do record diagnoses, but building your claim on the hope that they will is a gamble.
Service connection requires three things: a current disability, an event, injury, or disease in service, and a link between them. The first one comes from health care. If you have symptoms but no diagnosis, the place to start is your doctor, whether that's VA health care, a private provider, or community care. Get evaluated, get a diagnosis, get treated, and then file with that record behind you.

2. Adding a mental health condition can put your existing mental health rating back on the table
This one catches veterans who are already rated, and it can cost them.
VA rates nearly all mental health conditions under one formula, the General Rating Formula for Mental Disorders. It doesn't matter how many diagnoses you have: PTSD, depression, anxiety, and insomnia all describe overlapping symptoms, and VA can't rate the same symptoms twice. So VA assigns one mental health rating based on your overall level of occupational and social impairment.
Source: 38 C.F.R. § 4.130 (General Rating Formula); § 4.14 (avoidance of pyramiding).
What that means in practice
Say you're rated 50% for PTSD. You've been having trouble sleeping, or you've been diagnosed with depression, and you file a new claim for insomnia or depression.
VA does not add a second rating. It evaluates your mental health as a whole, which usually means a new exam that looks at your entire mental health picture, not just the new diagnosis. That exam can come out three ways:
- Your symptoms are worse: your single mental health rating may go up.
- Your symptoms are about the same: nothing changes. The new diagnosis is folded into the existing rating.
- The exam suggests improvement: VA can propose reducing the rating you already have.
Insomnia is an especially common example. "Chronic sleep impairment" is already listed in the rating criteria at the 30% level. If you're rated for PTSD or anxiety, your sleep problems are generally treated as part of that condition, not as something separately compensable.
That doesn't mean never file
If your symptoms have genuinely gotten worse, a claim for increase may be exactly the right move. The point is to go in knowing it's a full reevaluation, not a free add-on. Before you file:
- Make sure your treatment records reflect where you actually are now. A claim backed by current documentation of worsening is a very different claim from one backed by a new label alone.
- Look at the criteria for the level above your current rating and ask honestly whether your records support it. Our free Rating Criteria Lookup shows what each level requires.
- Know your protections. A rating in place for five years or more generally can't be reduced based on a single exam; VA has to find sustained improvement in the whole record, and a rating in place for 20 years is protected from reduction below that level except for fraud. Any proposed reduction comes with written notice and 60 days to respond with evidence.
Source: 38 C.F.R. § 3.344 (stabilization of ratings); § 3.951(b) (20-year protection); § 3.105(e) (reduction procedures).
VA proposed a new mental health rating formula in 2022. As of this writing it has not been finalized, so the current General Rating Formula still governs every mental health claim. We'll update this article if that changes.
3. File an Intent to File before anything else
An Intent to File holds your place. If you submit a complete claim within one year of it, VA treats the claim as filed on the Intent to File date, and benefits can be paid from that earlier date. It costs nothing and gives you a year to gather evidence without losing back pay. You can submit one online, by phone, or on VA Form 21-0966.
Source: 38 C.F.R. § 3.155(b).
4. Know the three pieces every claim needs
Before you file, check that you can point to each one:
- A current diagnosis (see #1).
- Something in service: an injury, event, exposure, or the first signs of the condition.
- A link (nexus) between the two, usually a medical opinion.
For presumptive conditions, such as those covered by the PACT Act for certain toxic exposures, the law supplies the link if you meet the service requirements. For everything else, the nexus is often where claims are won or lost.
5. Get your records before VA decides
Request your service treatment records and, if you've filed before, your claims file (C-file). Read them. You want to know what's in there, and what isn't, before an examiner or rater reads it. Gaps you find now can be filled with private records or statements. Gaps you find in a denial letter cost you a review cycle.
6. Don't miss your exam
If you fail to report for a scheduled exam without good cause, VA decides an original claim on whatever evidence it already has. A claim for an increase is denied outright. If you truly can't make it, contact VA or the exam contractor before the appointment to reschedule, and keep a record that you did.
Source: 38 C.F.R. § 3.655.
7. Describe your condition accurately, including bad days
Veterans tend to minimize. At an exam, "I'm fine" or "I manage" becomes the record. Describe what a normal day looks like, what a bad day looks like, how often bad days happen, and what you can't do during them. Don't exaggerate either: inconsistency with your records hurts credibility.
Statements from a spouse, friend, or someone you served with can describe what they've seen. VA Form 21-10210 is the form for those lay and witness statements.
8. You don't have to pay anyone to file your first claim
Accredited Veterans Service Organizations help with claims at no cost. VA-accredited attorneys and claims agents can charge fees, but only for work done after VA issues its initial decision. Anyone charging to prepare or file your initial claim is outside those rules. Before working with anyone, confirm their accreditation using VA's accreditation search on the VA Office of General Counsel website.

If you've already filed
If you've received a decision you disagree with, the clock is already running. Here's how to choose between a Supplemental Claim, Higher-Level Review, and Board Appeal. And if your combined rating doesn't add up the way you expected, here's how VA actually does the math.
