The VA claims glossary: every confusing term, in plain English
The acronyms and terms that show up in your letter, translated. Bookmark this one and come back to it.
VA decision letters and the claims process are stuffed with acronyms. C&P, DBQ, HLR, ITF, SMC, TDIU. Most of them are never spelled out where you can see them, and the ones that are get buried in regulation-speak. This page is the decoder ring. Every term below is written in plain English, grouped alphabetically so you can jump to what you need. Where we have a full guide on a term, the term links straight to it.
How to use this
Skim the letter headers to find your term, or use your browser's find (Ctrl+F or Cmd+F) to search this page for the exact acronym on your letter. If a definition raises more questions, follow the link. And if you want your actual letter read back to you in plain English, the Decode tool at the bottom does that with your real document.
B
Back pay (also called retroactive pay): the lump sum the VA owes you for the months between your effective date and the day it finally approved your claim. If your claim took a year to decide and the effective date is the day you filed, you are owed roughly a year of payments in one check.
Benefit of the doubt: a rule that when the evidence for and against your claim is roughly equal (about 50-50), the VA is required to decide in your favor. You do not have to prove your case beyond all doubt, only tip it to at least even. This lives in 38 CFR §3.102.
Bilateral factor: an extra boost to your rating when you have disabilities affecting both arms, both legs, or paired muscle groups. The VA combines those paired ratings, then adds an extra 10 percent of that combined value. It is explained inside our VA math guide.
Board / BVA (Board of Veterans' Appeals): the appeal lane where a Veterans Law Judge in Washington reviews your case, sometimes at a hearing. It is one of the three decision-review options, and usually the slowest. See Supplemental vs HLR vs Board.
Buddy statement / lay statement (VA Form 21-10210): a written statement from you, a fellow service member, a spouse, or anyone who witnessed your injury or your symptoms. You do not have to be a doctor to describe what you lived through, and these statements can carry real weight when your records have gaps.
C
C&P exam (Compensation and Pension exam): the medical exam the VA sends you to so an examiner can evaluate your claimed condition and its severity. The examiner does not decide your claim, but their report heavily influences the rater who does. Preparing for it is one of the highest-leverage things you can do.
CUE (Clear and Unmistakable Error): a special challenge you can file when a past VA decision contains an undebatable error that, if corrected, would clearly have changed the outcome. The bar is very high. It is not for "I disagree," it is for "the VA plainly got a fact or a law wrong."
Combined rating: your single overall disability percentage after the VA folds all your individual ratings together using its own math, not simple addition. A 50 and a 30 combine to 70, not 80. The full walkthrough is in How VA math works.
D
DBQ (Disability Benefits Questionnaire): a standardized VA form that captures the medical findings for a specific condition. A VA examiner fills one out after a C&P exam, and in some cases your own private doctor can complete one to add to your evidence.
DEA / Chapter 35 (Dependents' Educational Assistance): an education benefit for the spouse and children of a veteran who is rated permanently and totally disabled (P&T), or who died from a service-connected condition. It helps pay for college, training, and some other programs.
Deferred: a status on your decision meaning the VA decided some issues but set one or more aside to gather more evidence or order another exam. Deferred is not denied. It means "not yet," and that issue is still open.
DIC (Dependency and Indemnity Compensation): a monthly tax-free payment to eligible survivors (a surviving spouse, children, or parents) when a veteran dies from a service-connected condition, or in some cases after being rated totally disabled for a set period.
DRO (Decision Review Officer): a senior VA reviewer. Under the current appeals system you can request a Higher-Level Review, which is a fresh look by a more experienced reviewer of the same rank as a DRO, without submitting new evidence.
Duty to assist: the VA's legal obligation to help you gather the evidence for your claim, including getting your service and VA medical records and providing an exam when one is needed. When the VA fails this duty, it can be grounds to challenge the decision. See 38 CFR §3.159.
E
Effective date: the date your benefits are treated as starting, which drives how much back pay you get. It is usually the date the VA received your claim or your Intent to File, though presumptive and other rules can move it. This one date can be worth thousands of dollars.
EP (End Product): the internal VA tracking code for a work item on your claim. You may see an EP number or code in your file. It is a workflow tag the VA uses to manage and count claims, not a rating or a decision about your benefits.
H
HLR (Higher-Level Review): one of the three ways to challenge a decision. A more senior reviewer takes a completely fresh look at the same evidence you already submitted. You cannot add new evidence in an HLR, so it is the right lane when you believe the VA made an error on the record it already had.
I
IU: see TDIU below. "IU" (Individual Unemployability) and "TDIU" refer to the same benefit.
ITF (Intent to File): a simple notice that tells the VA you plan to file a claim. It locks in a potential effective date, giving you up to a year to gather evidence and submit the full claim while still being paid back to the ITF date. Filing one early is often the cheapest way to protect back pay. See how to file.
L
Lay statement: see Buddy statement above. A "lay" statement simply means it comes from a non-expert (you or a witness) rather than a medical professional.
N
Nexus: the link between your current condition and your military service. "Nexus" is Latin for connection. A nexus letter is a medical opinion, usually from a doctor, stating that your condition is "at least as likely as not" caused by or related to service. It is often the missing piece in a denied claim.
P
P&T (Permanent and Total): a status meaning you are rated 100 percent (total) and the VA does not expect your condition to improve (permanent), so it will not schedule future re-examinations. P&T can unlock added benefits for you and your dependents, such as Chapter 35 education aid.
Preparation for Decision: see RFD below. This is the claim-tracker phase that means your evidence is gathered and a rater is getting ready to decide. It does not mean a decision is guaranteed that day. Our timeline guide explains the phases.
Presumptive condition: a condition the VA automatically presumes is connected to your service based on where and when you served, so you do not have to prove the nexus yourself. Burn-pit and Agent Orange conditions under the PACT Act are common examples.
Pyramiding: a rule that the VA cannot rate the same symptom twice under two different diagnostic codes. If two conditions produce the same symptom, you generally get rated once for it. This is why some stacked claims do not raise your combined number the way you would expect. See 38 CFR §4.14.
R
Rating decision: the official VA document that lists each condition you claimed, whether it was granted or denied, the percentage assigned, and the reasons. It comes with a cover letter. Learn to read yours in how to read your decision letter.
RFD (Ready for Decision) / Preparation for Decision: the claim-tracker stage where evidence gathering is finished and your claim is queued for a rater to make the call. It is a good sign of progress, but the length of this stage varies widely.
S
Secondary service connection: when one service-connected condition causes or worsens a second condition, and the second one gets service-connected too. Sleep apnea caused by a service-connected mental health condition is a classic example. The rule is 38 CFR §3.310.
Service connection: the core finding behind almost every claim: that your current disability is linked to your military service. Establishing it generally takes a current diagnosis, an in-service event or exposure, and a nexus tying the two together.
SMC (Special Monthly Compensation): extra payment above the standard rating tables for especially serious situations, such as loss of use of a limb, being housebound, needing daily aid and attendance, or certain other losses. SMC-K, for example, is an added amount for specific losses.
STRs (Service Treatment Records): your military medical records, the sick-call visits, exams, and complaints documented while you served. They are often the single most important evidence for showing an in-service event, which is why gaps in them matter so much.
Supplemental Claim: one of the three decision-review lanes. You reopen a decided claim by adding new and relevant evidence the VA did not have before. It is often the right move when a denial came down to missing evidence you can now supply.
T
TDIU (Total Disability based on Individual Unemployability): a benefit that pays at the 100 percent rate even if your combined rating is below 100, when your service-connected conditions keep you from holding steady, gainful work. Also called IU. It is one of the most valuable and most overlooked benefits.
V
VA-accredited representative: a person the VA has formally authorized to help you with your claim, either a VSO representative, an accredited claims agent, or an accredited attorney. Accreditation is the VA's stamp that they are allowed to represent veterans. You can check accreditation on the VA's website, and a free VSO is a great place to start. Compare your options in VSO vs attorney vs consultant.
VA math / combined-ratings: the method the VA uses to merge your individual ratings into one combined number. It is not addition. Each condition only reduces the "healthy" percentage that is left. Full walkthrough in How VA math works.
VASRD (VA Schedule for Rating Disabilities): the master rulebook (38 CFR Part 4) that assigns a diagnostic code and rating criteria to each condition. When a rater decides you are "30 percent" for something, they are applying the VASRD criteria for that code.
VSO (Veterans Service Organization): an organization such as the DAV, VFW, American Legion, or Paralyzed Veterans of America whose accredited representatives help you file and appeal claims for free. This is the help we point you to for advice on your specific claim. See VSO vs attorney vs consultant.
A word on "claim sharks"
You may run into companies that charge steep fees, sometimes a slice of your back pay, to "help" with a claim. Only a VA-accredited representative may legally represent you, and accredited VSOs do it for free. If someone pressures you to pay before you file, or promises a guaranteed rating, that is a red flag. Nobody can guarantee an outcome.
Where to verify any of this
These definitions are plain-English summaries. The binding rules live in the regulations. Ratings and math are in 38 CFR Part 4, and the rules raters apply to service connection, effective dates, and secondaries are in 38 CFR Part 3. VA also explains the process in plain language across VA.gov. When a term on your own letter does not match what you expected, that is worth raising with a free accredited representative.
