VA claims glossary

Occupational and social impairment

The phrase VA uses in the General Rating Formula for Mental Disorders (38 CFR § 4.130) to describe how symptoms affect work and relationships. Published percentage levels are tied to specific wording such as “occasional decrease in work efficiency,” “reduced reliability and productivity,” “deficiencies in most areas,” and “total occupational and social impairment.”

Why veterans hit this: Mental-health ratings are based on this functional language, not on a diagnosis name alone. A clinician note that only lists a diagnosis, without describing work and social function, often leaves the rater with less to apply.

Incapacitating episode

In the intervertebral disc syndrome (IVDS) formula, a period of acute signs and symptoms that requires bed rest prescribed by a physician and treatment by a physician (38 CFR § 4.71a, Diagnostic Code 5243). The published percentages depend on total duration of those episodes in the past 12 months.

Why veterans hit this: Self-described “bad days” are not the same thing. The formula looks for physician-prescribed bed rest and treatment. Spine conditions can also be rated under the General Rating Formula for the Spine using range of motion; VA uses whichever method is more favorable on the evidence.

Static disability

Also called: no future exam · static rating

A disability VA treats as not expected to improve enough to change the rating. When VA finds a rating static, it generally does not schedule a routine future examination for that condition. Permanence and “static” are related but not identical labels.

Why veterans hit this: A static finding can reduce the chance of a routine re-exam, but it is not a promise that a rating can never change. VA can still propose a reduction if later evidence shows material improvement, subject to the reduction rules in 38 CFR § 3.344.

Combined rating

Also called: VA math · combined evaluation

The single percentage VA publishes after combining multiple disability ratings with the Combined Ratings Table in 38 CFR § 4.25. Ratings are not added (50 + 30 is not 80). Each new rating is applied to the remaining “efficiency.” Bilateral conditions can also receive the bilateral factor in 38 CFR § 4.26 before the table is applied.

Why veterans hit this: Monthly compensation uses the combined evaluation (and dependents), not the sum of the individual percentages. Understanding the table helps you check a decision letter, not predict a future award.

Pyramiding

The rule in 38 CFR § 4.14 that the same disability, or the same manifestation of a disability, cannot be rated more than once. Separate ratings are allowed when the manifestations are distinct (for example, a knee limitation of motion rated separately from a distinct neurologic finding when the regulation permits it).

Why veterans hit this: Veterans sometimes expect every diagnosis to add a new percentage. If two diagnoses describe the same functional loss, VA may assign one rating. That is a legal evaluation rule, not a personal judgment about the veteran.

Nexus

Also called: medical nexus · nexus opinion

The medical link between a current disability and an in-service injury, disease, event, or an already service-connected condition. A nexus opinion is a clinician’s statement about that link. VA often looks for language on the “at least as likely as not” (50 percent or greater) standard, but the whole file matters — not one magic sentence.

Why veterans hit this: For many direct and secondary claims that are not presumptive, missing or weak medical-link evidence is why a claim is deferred or denied. A purchased letter is not automatically persuasive; the examiner or private clinician still has to explain the reasoning from the facts.

Presumptive service connection

Also called: presumptive

A path where VA may grant service connection for a listed condition without a veteran-supplied nexus opinion if the service, location, and timing rules in the regulation are met (for example certain PACT Act, Agent Orange, Camp Lejeune, or Gulf War provisions). VA can still require a current diagnosis and may still develop other evidence.

Why veterans hit this: Presumptive status does not mean automatic approval, and it does not replace the need for a current disability. It changes what medical-link evidence VA must still demand for that listed condition.

Secondary service connection

Also called: secondary claim

Service connection for a disability that was caused or aggravated by an already service-connected condition (38 CFR § 3.310). The “in-service event” is the primary service-connected disability, not a new in-service injury.

Why veterans hit this: Common research pairs include mental-health conditions and sleep disturbance, spine conditions and radiculopathy, or medication side effects. Each pair still needs its own diagnosis and medical-link evidence. A website list is a research lead, not a grant.

Aggravation

A worsening of a pre-existing condition beyond its natural progress, attributed to service (or, for secondaries, to a service-connected condition). VA generally needs evidence of the baseline before service or before the claimed aggravation, plus evidence of the increase.

Why veterans hit this: Aggravation claims often fail when there is no documented baseline. “It got worse after service” is a starting observation, not the complete legal showing.

Direct service connection

The classic three-part showing: a current disability, an in-service injury, disease, or event, and a medical nexus between the two. Combat, in-service diagnosis, and chronicity rules can change how those elements are proven, but they do not erase the need for a current disability.

Why veterans hit this: Most first claims are built on this path unless a presumption applies. Organizing those three questions before you file is the educational purpose of the free Coach preview and the paid dashboard.

C&P exam

Also called: compensation and pension exam · VA exam

A medical examination or records review VA orders to gather evidence for a claim. The examiner (often a contractor such as QTC, VES, or Optum Serve) completes findings VA uses with the rest of the file. It is not treatment and not a guarantee of a rating.

Why veterans hit this: The exam is usually short. Bringing a clear history, current treatment records, and an accurate description of function matters more than rehearsed phrases. Missing an exam without good cause can lead to a decision on the evidence already in the file.

Higher-Level Review (HLR)

Also called: HLR · VA Form 20-0996

An Appeals Modernization Act lane in which a more senior reviewer looks at the same evidence already in the file for difference of opinion or error. You generally cannot add new evidence on an HLR. A finding of “duty to assist error” returns the claim for more development and is not a denial.

Why veterans hit this: Choose HLR when you believe VA misapplied the law or overlooked evidence already submitted. If you have new records, a supplemental claim is usually the matching lane.

Supplemental claim

Also called: VA Form 20-0995

An AMA review lane used when you have new and relevant evidence that was not before VA when it made the decision you want reviewed. VA’s duty to assist applies in this lane.

Why veterans hit this: “New and relevant” is a legal standard: the evidence must be new to that decision and tend to prove or disprove a matter at issue. Repeating the same records usually is not enough.

Board Appeal

Also called: BVA · VA Form 10182

A request for a Veterans Law Judge at the Board of Veterans’ Appeals to review the decision. Under the AMA you choose a docket: Direct Review, Evidence Submission, or Hearing. Timelines are typically longer than HLR or supplemental claims.

Why veterans hit this: The Board is the last VA stop before the Court of Appeals for Veterans Claims. The docket you pick changes whether you can add evidence and how long the wait usually is.

Duty to assist

VA’s statutory duty (38 U.S.C. § 5103A / 38 CFR § 3.159) to help develop a claim — for example requesting federal records or scheduling an exam — once a substantially complete claim is filed. It is not a duty to grant the claim.

Why veterans hit this: On an HLR, a “duty to assist error” finding is favorable: the prior decision is typically voided for more development, and the effective-date stream is usually preserved. Read the letter before assuming it is a denial.

New and relevant evidence

The AMA standard for reopening a decided issue on a supplemental claim. “New” means not previously part of that decision’s record. “Relevant” means it tends to prove or disprove a fact needed for the benefit.

Why veterans hit this: A new buddy statement, a later diagnosis, or a private DBQ can qualify if it actually speaks to an open element. A reprint of records VA already had generally does not.

TDIU

Also called: IU · individual unemployability · total disability based on individual unemployability

A way VA may pay at the 100% compensation rate when service-connected disabilities prevent substantially gainful employment, even if the combined schedular rating is below 100%. The published schedular gate in 38 CFR § 4.16(a) is one disability at 60% or a combined 70% with at least one disability at 40%. Extraschedular TDIU under § 4.16(b) is a referral path, not a self-grant.

Why veterans hit this: TDIU is about inability to secure or follow substantially gainful work because of service-connected disability. Marginal or sheltered work can still support a TDIU theory. VA, not a website calculator, decides the claim.

Aid and attendance

Also called: A&A · SMC A&A

A higher level of special monthly compensation when a veteran (or, in some programs, a surviving spouse) needs regular help with daily living or is bedridden, under the criteria in 38 CFR § 3.352 and the SMC rules in § 3.350. It is not the same as housebound, and it is not automatic at 100%.

Why veterans hit this: A&A looks at actual need for assistance — dressing, bathing, feeding, toileting, or protection from the hazards of the daily environment — not at the combined percentage alone. VA Form 21-2680 is the usual examination vehicle.

Housebound

Also called: SMC-S

A special monthly compensation level for veterans who are permanently housebound by reason of service-connected disability, or who have a single 100% service-connected disability plus additional service-connected disabilities independently rated 60% or more (38 CFR § 3.350(i)).

Why veterans hit this: Housebound is a statutory SMC question, not a lifestyle description. “I do not go out much” is not the legal test. The 100% + 60% path is a ratings-arithmetic path; the factual housebound path is about being substantially confined to the home.

Special monthly compensation (SMC)

Also called: SMC-K · SMC-L · SMC-S

Additional tax-free compensation above the basic 0–100% schedule for specific anatomical losses, loss of use, aid and attendance, housebound status, and certain combinations (38 CFR § 3.350). SMC-K is a common anatomical-loss / loss-of-use rate; higher letters (L through R) reflect more extensive need or loss.

Why veterans hit this: SMC is easy to miss because it is not a “new diagnostic code” on the basic schedule. Loss of use of a creative organ, housebound, and A&A are frequent examples. The letter on a decision (K, S, L) is the legal level — not a grade a website assigns.

Permanent and total (P&T)

Also called: P&T · 100% P&T

A finding that a total (100% schedular or TDIU) disability is reasonably certain to continue throughout the veteran’s life. P&T can unlock related benefits such as CHAMPVA for qualifying dependents and Chapter 35 education, subject to those programs’ own rules.

Why veterans hit this: A 100% rating is not automatically P&T. Temporary 100% ratings (surgery, convalescence, or a scheduled future exam) are different. Read the decision codesheet and the “future exam” line before assuming dependents’ benefits apply.

DBQ

Also called: Disability Benefits Questionnaire

A structured medical questionnaire aligned to a condition’s rating criteria. VA examiners complete DBQs at C&P exams. A private clinician may complete a public DBQ; VA still weighs it with the rest of the file and is not required to adopt its conclusions.

Why veterans hit this: A completed DBQ can organize the exact findings a rater looks for (range of motion, frequency, treatment). It is evidence, not a rating decision. Public DBQs remain available on VA.gov for many conditions.

Lay evidence

Also called: buddy statement · lay statement

First-hand observations from a veteran, family member, coworker, or fellow service member about events or symptoms they personally saw. Lay people generally cannot diagnose a medical condition, but they can describe what they observed. VA Form 21-10210 is the usual witness form; veterans also use personal statements such as VA Form 21-4138.

Why veterans hit this: Lay evidence is often the only record of an in-service event or of how symptoms look at home. Vague praise (“he is a great guy”) is weak; specific dates, duties, and observed limitations are stronger. It still does not replace medical evidence when a medical question is at issue.

Diagnostic code (DC)

Also called: DC code

The four-digit number in 38 CFR Part 4 that identifies how a disability is evaluated (for example DC 6260 tinnitus, DC 9411 PTSD). The code points to the published criteria. Analogous or hyphenated codes are used when a condition is rated under a nearby schedule.

Why veterans hit this: The diagnosis name on a medical record is not always the DC VA assigns. Looking up the code on a decision letter tells you which criteria VA actually applied.

Effective date

The date from which VA pays an awarded benefit, generally governed by 38 CFR § 3.400. Common anchors include the date VA received the claim or intent to file, the date entitlement arose, or a liberalizing-law date. Back pay is the money between the effective date and the date VA issues payment.

Why veterans hit this: A later filing can cost months of pay even if the rating is the same. An intent to file can preserve a date if the completed claim arrives within one year. Effective-date disputes are a frequent reason to talk with an accredited representative.

Intent to file

Also called: ITF · VA Form 21-0966

A notice that tells VA you plan to file a claim. If VA receives a substantially complete application within one year of the intent to file, the effective date can generally relate back to the ITF date (38 CFR § 3.155).

Why veterans hit this: An ITF can protect an effective date while you gather records. It is not a claim by itself, and it expires if you do not complete the filing in time.

Favorable findings

Facts VA has already ruled in your favor in a decision (for example, that an in-service event occurred or that a current diagnosis is established). Under the AMA, those findings are generally binding on later reviews of the same claim unless rebutted by clear and convincing evidence.

Why veterans hit this: You do not have to re-prove a locked favorable finding on the next appeal of that issue. Cite them by name when you talk with a VSO or file a review.
