VA PTSD Claims Guide

Post-Traumatic Stress Disorder is one of the most commonly claimed mental health conditions in the VA disability system. It is rated under DC 9411, which cross-references the General Rating Formula for Mental Disorders found at 38 CFR § 4.130. Unlike most physical conditions, PTSD is evaluated on occupational and social impairment rather than on measurable clinical findings such as lab values or range of motion.

This guide covers the three elements required for service connection, how stressor categories affect evidence requirements, what VA actually looks for in the record, the direct and secondary/aggravation pathways to service connection, how the rating formula works, the evidence that has moved published Board decisions, why these claims get denied, a checklist before you file, the claims process step by step, and what conditions are commonly linked to PTSD.

We analyzed published Board of Veterans' Appeals decisions on PTSD for patterns in what evidence tends to be present in claims that get granted, and what tends to be missing in claims that get denied. These are patterns, not promises. Board decisions bind only the case they decide and are not VA policy; your own facts and evidence determine your outcome.

VA service connection for PTSD requires all three of the following (see 38 CFR § 3.304(f)):

1. A current diagnosis. The diagnosis must be made by a licensed mental health professional using the criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), as required by 38 CFR § 4.125(a). A self-reported belief that one has PTSD does not satisfy this element on its own, and a record that only mentions PTSD in passing, without a documented DSM-5 evaluation behind it, is often not enough either.
2. A credible in-service stressor. A stressor is a traumatic event that occurred during military service. Under DSM-5 Criterion A, qualifying events involve actual or threatened death, serious injury, or sexual violence experienced directly, witnessed, or learned about in a specific context. The evidence required to establish that the stressor occurred depends on the category of stressor involved (see Stressor Categories below).
3. A medical nexus linking the diagnosis to the in-service stressor. A medical opinion from a qualified provider must state that the current PTSD is connected to the identified in-service stressor. The standard phrase used in VA practice is "at least as likely as not," meaning a probability of 50% or greater. (See our Nexus Letters Guide for what makes a strong opinion.) (38 CFR § 3.304(f))

The great majority of PTSD claims are established directly, through the three-element test above: a current diagnosis, a verified stressor, and a medical nexus tying the two together. Two other pathways exist and are worth knowing about, even though they come up far less often for PTSD than direct connection does.

Direct Service Connection

A veteran demonstrates that PTSD arose from a specific in-service traumatic stressor, established under one of the five stressor categories described above, with a current DSM-5 diagnosis and a medical nexus connecting the two. This is the pathway behind the overwhelming majority of granted PTSD claims.

Whether your claim turns on the stressor, the diagnosis, or the nexus, the record VA actually reviews centers on a small set of documents and data points.

• The DSM-5 diagnosis itself: a mental health evaluation, ideally by a psychiatrist or psychologist, that documents the specific DSM-5 Criterion A through H findings, not just a chart note that mentions "PTSD" in passing or "by history."
• Stressor evidence matched to the applicable category: service personnel records, unit histories, deployment orders, and combat decorations for combat and in-service categories; law enforcement, medical, or counseling records and behavioral-change evidence for MST and personal-assault claims; buddy statements corroborating the event for any category.
• Treatment records: ongoing mental health treatment, therapy notes, medication history, and any crisis-line or emergency contact close in time to service, all of which help establish that symptoms began around service and have continued.
• The diagnostic codes involved: DC 9411 for PTSD itself, plus whatever code applies to a condition you're connecting to it as a secondary claim, for example DC 6847 (sleep apnea), DC 8100 (migraines), DC 7522 (erectile dysfunction), or DC 7101 (hypertension), each discussed further in Common Secondary Conditions below.
• The actual form the examiner fills out: a Disability Benefits Questionnaire (DBQ) for mental disorders, discussed in more detail later in this guide.
• The medical nexus opinion: a statement, with reasoning, that connects the current PTSD diagnosis to the identified stressor at "at least as likely as not" or higher.

Beyond the general "no nexus," "no current diagnosis," and "unverified stressor" reasons covered above, a few specific denial patterns show up often enough in published decisions to call out on their own.

VA may not evaluate the same disability, or the same manifestation of disability, under multiple diagnostic codes. For mental health conditions, this means a veteran generally receives one combined mental health rating even when multiple diagnoses exist (PTSD, major depressive disorder, anxiety disorder). (see 38 CFR § 4.14)

Symptoms that overlap completely between two mental health diagnoses produce only one rating. However, when two mental health diagnoses produce distinct, non-overlapping symptoms, separate ratings may be possible. This determination requires careful review of the clinical evidence.

The pyramiding rule does not apply between mental health conditions and physical secondary conditions. Sleep apnea, migraines, and gastrointestinal conditions secondary to PTSD are rated separately under their own diagnostic codes. See our Pyramiding Guide for more. Do not file a physical secondary condition, such as sleep apnea or migraines, as though it were part of the PTSD claim itself; file it as its own secondary claim so it gets its own rating.

Patterns the published DC 9411 decisions and the rating rules flag most often. Among the Board's classified service-connection denials for PTSD, the most common reasons are a missing medical nexus, no current diagnosis, and no verified in-service stressor. The pitfalls below are more about how a claim or appeal is handled procedurally.

A printable one-page version of these pitfalls, Common Reasons PTSD Claims Are Denied, is in the PTSD Visual Guide Library.

A printable side-by-side version, PTSD Claim Do's and Don'ts, is in the PTSD Visual Guide Library.

The evidence required for the in-service stressor element varies significantly based on how the stressor is classified. 38 CFR § 3.304(f) defines five stressor categories, each with its own evidence standard, some of them considerably easier to satisfy than a full record search. For a deeper walkthrough of the verification process itself, including JSRRC searches, the 60-day window rule, the VSR/RVSR workflow, and BVA outcome data, see the VA PTSD Stressor Verification guide.

A special rule applies when a mental disorder is diagnosed in service connection with a claim involving a traumatic event. When it applies, VA assigns a minimum 50% rating and schedules a mandatory re-evaluation between six months and one year after the rating is assigned. At re-evaluation, the rating is adjusted up or down based on current symptoms. (see 38 CFR § 4.129)

This provision is frequently misunderstood. It does not apply to every PTSD claim. It applies when VA establishes service connection for a mental disorder related to a traumatic event AND the evidence shows the veteran experienced an acute situational reaction or mental disorder in connection with that event during service. The key practical consequence is that the 50% rating floor prevents an initial service connection decision from coming back at 0% or 10% without a subsequent re-evaluation. (38 CFR § 4.129)

PTSD is rated under DC 9411 using the General Rating Formula for Mental Disorders at 38 CFR § 4.130. The formula uses six rating levels. Mental health ratings are not a continuous scale. The available percentages are 0%, 10%, 30%, 50%, 70%, and 100% only. There are no 20%, 40%, 60%, 80%, or 90% ratings under this formula.

The rating reflects occupational and social impairment, meaning the combined impact on employment and on personal and community relationships.

Rating agencies evaluate mental disorders based on all symptoms present, not only on those specifically listed in the rating criteria. A symptom not explicitly named in the formula can still support a higher rating if it contributes to occupational or social impairment consistent with that level. (see 38 CFR § 4.126)

The evaluation captures the overall level of impairment in ordinary conditions of daily life including work, school, and social activities. The C&P examiner is directed to describe the severity, frequency, and duration of symptoms and to assess the degree of social and occupational impairment they cause.

We analyzed the Board's published DC 9411 decisions: a private nexus opinion in the file goes with a much higher grant rate, shown below.

A DSM-5 diagnosis, documented as such. For PTSD ratings, the C&P examination carries the most weight in determining the rating level. The examiner uses a Disability Benefits Questionnaire (DBQ) for mental disorders and assesses the current level of occupational and social impairment. See our DBQ Library for the form itself. The examiner is not required to document symptoms the veteran does not report during the exam.

A nexus opinion that explains its reasoning. Across published decisions, an opinion that walks through the "why," addressing the specific stressor, the veteran's history, and the mechanism connecting the two, has been given far more weight than one that simply states a conclusion. This has held true regardless of whether the opinion came from a private provider or a VA examiner; what matters is the reasoning, not just who wrote it.

Stressor corroboration. A fellow service member's statement describing the same event, personnel or exposure records placing the veteran at the right place and time, or unit records documenting the incident. See our PTSD Stressor Verification Guide.

A consistent account, told the same way every time. The Board has repeatedly leaned on whether a veteran's account of the stressor and the onset of symptoms stayed the same across statements, exams, and hearings over the years. Tell the same honest account to every doctor, on every form, and at any hearing.

Contemporary treatment records. Ongoing treatment helps prove your symptoms started around service and continued. A documented crisis-line call, an emergency visit, or the start of regular therapy close in time to separation can matter as much as anything else in the file. Getting help also protects your health, which matters most.

Lay statements: First-person descriptions of symptoms, and statements from a spouse, family members, or people who served alongside you who directly observed nightmares, anger, hypervigilance, or avoidance, contribute to the evidence record. See our Buddy & Lay Statements Guide. Lay statements are admissible for describing symptoms a person can directly observe. (Buchanan v. Nicholson, 451 F.3d 1331 (Fed. Cir. 2006).)

Total Disability Individual Unemployability (TDIU) pays compensation at the 100% rate when a veteran cannot maintain substantially gainful employment due to service-connected disabilities. Under 38 CFR § 4.16(a), a veteran with a single service-connected mental disorder rated at 70% or higher may qualify for TDIU if that condition prevents employment. A veteran with a PTSD rating of 60% combined with other service-connected conditions totaling 70% or higher may also qualify. Unemployability due solely to PTSD is among the most common TDIU claims adjudicated.

A claim filed under a specific label, "PTSD," "depression," "anxiety," is not limited to that label. Under M21-1, Part V, Subpart iii, Chapter 13, Section 1.a, VA must read a mental-disorders claim as covering any mental disability that may reasonably be defined by:

• the description of the claim,
• the symptoms the claimant describes,
• the information and evidence the claimant submits, and
• any other information and evidence VA has obtained.

This is the "sympathetic reading" rule. It is grounded in Robinson v. Shinseki, 557 F.3d 1355 (Fed. Cir. 2009), which held that VA must construe pro se veteran filings sympathetically. The M21-1 explicitly states: "A sympathetic reading of pleadings cannot be based on a standard that requires legal sophistication and must consider whether all submissions taken together have articulated a claim."

Why this matters for veterans

Veterans regularly file under a single mental-health label and end up with a C&P examiner who diagnoses a different mental disorder. Common patterns:

• Veteran files for PTSD, examiner diagnoses Major Depressive Disorder (MDD) instead.
• Veteran files for PTSD, examiner diagnoses adjustment disorder, anxiety disorder unspecified, or persistent depressive disorder.
• Veteran files for "anxiety," examiner finds the more accurate diagnosis is PTSD or panic disorder.
• MST-based filings often shift between PTSD, depression, and anxiety diagnoses across examiners.

Under Robinson and the M21-1, none of these should produce a denial that says "you claimed PTSD but you have MDD." VA is required to evaluate whatever mental disability the evidence reasonably supports. The rating schedule itself, at 38 CFR § 4.130, uses the same General Rating Formula for nearly all mental disorders, so the rating outcome is usually the same regardless of which mental-health diagnosis prevails.

The duty-to-assist anchor

The same M21-1 section reminds raters that under 38 CFR § 3.159, the duty to assist is triggered by a substantially complete application, which requires the benefit claimed plus any medical condition on which it is based, including a description of symptoms of a body part or system. A veteran does not need a precise DSM-5 diagnosis to start the process. Symptoms are enough.

What to do if VA denied your claim on the "wrong label" theory

• Read the denial carefully. If VA said something like "the veteran claimed X but the diagnosis is Y, so the claim is denied," that is a Robinson / M21-1 V.iii.13.1.a violation.
• File a Higher-Level Review (HLR) arguing the rater misapplied the sympathetic-reading duty. Cite Robinson v. Shinseki and the M21-1 section in the HLR request. See HLR Guide.
• Or file a Supplemental Claim with the diagnostic-broadening evidence and an explicit statement that the claim should be read as covering all mental disorders supported by the record. See Supplemental Claim Guide.
• Do not assume you must refile from scratch. Doing so resets your effective date. The sympathetic-reading rule is supposed to preserve the original date.

Once you file, your claim moves through a series of hand-offs. Understanding who does what helps you know who to contact, and what to expect, at each stage.

1. You file the claim. Directly with VA, through VA.gov, or with the help of an accredited representative.
2. VA acknowledges the claim and assigns it for development. A Veteran Service Representative (VSR) is assigned to gather your service treatment records, VA and private medical records, and any other evidence needed.
3. The VSR orders a Compensation & Pension (C&P) exam. Nearly all PTSD claims require one, since the exam produces the DSM-5 diagnosis and the assessment of occupational and social impairment the rating depends on.
4. The C&P exam is conducted. By a VA clinician or a contracted examiner, who completes a Disability Benefits Questionnaire (DBQ) for mental disorders, documenting the diagnosis, symptom severity, and, where relevant, a nexus opinion.
5. The file goes to a Rating Veteran Service Representative (RVSR), the "rater." The rater reviews the complete file, including the exam results, and decides whether service connection is warranted and at what percentage.
6. A senior reviewer may review the decision before it's finalized, depending on the complexity of the claim.
7. VA issues the decision letter. This states whether the claim is granted or denied, the rating percentage if granted, and the reasons behind the decision.
8. If you disagree, you choose an appeal lane. Higher-Level Review, Supplemental Claim, or a Board appeal, covered later in this guide.

A Disability Benefits Questionnaire (DBQ) is the standardized form an examiner completes for your condition. For PTSD, it structures the exam findings into the specific occupational and social impairment criteria the rating schedule requires, along with a nexus opinion where one is requested. See the DBQ Guide for how these forms work, including whether a private DBQ completed by your own doctor can be submitted instead of relying solely on a VA exam.

Before your C&P exam, bring a clear, specific, and honest account of your symptoms, focus on your worst days and how the condition affects daily function, not just how you feel on an average day. Be consistent with what's already in your medical records and prior statements. The examiner is not required to document symptoms you do not report, so do not minimize what you're actually experiencing. For a full walkthrough of what to expect and how to prepare, see the C&P Exam Prep Guide and the C&P Exam Reference.

Your decision letter has two parts: a narrative section explaining the reasoning (often called "reasons and bases"), and a codesheet showing the actual rating percentage, the effective date, and the diagnostic code used. See the Reading Your Decision Letter Guide for how to find and interpret each part, or use the Letter Interpreter tool to upload your own letter and get a plain-English breakdown.

If your claim is denied, or the rating is lower than you expected, you have three main lanes:

• Supplemental Claim: refile with new and relevant evidence, such as a new nexus opinion, a corroborating buddy statement, or updated treatment records. See Supplemental Claim Guide.
• Higher-Level Review (HLR): a senior reviewer looks at the same evidence again for a difference of opinion, no new evidence is added. See HLR Guide.
• Board Appeal: your case goes to a Veterans Law Judge at the Board of Veterans' Appeals, with options for a direct review, an evidence docket, or a hearing. File on time and name the exact decision and issues you are appealing. See Board Appeal Guide.

Not sure which lane fits your situation? See the Appeals decision guide for a side-by-side comparison of all three. If your denial turned on VA treating a different mental-health diagnosis as fatal to your PTSD claim, see Sympathetic Reading for the specific argument and where to raise it.

Winning service connection is step one. VA then assigns a rating percentage and an effective date, which set your monthly payment and any back pay.

• Match your symptoms to the exact words of the rating criteria. Published decisions have secured a higher rating and an earlier start date where an exam used language listed directly in the rating rules, for example "difficulty adapting to stressful circumstances."
• Lean on treatment records when an exam seems to downplay you. Where treatment records document something more severe than a single exam captured, for example an actual suicide attempt where an exam recorded only ideation, the Board has given the treatment records more weight.
• Do not minimize your symptoms. The Board has recognized that some veterans tend to underreport, and has still granted a higher rating where the record supported it. Be honest about your worst days, not just your good ones.
• Keep appealing on time to protect your earliest effective date. Continuously pursuing a claim rather than letting a decision go final, and then refiling later, can preserve an earlier effective date.

Keep your treatment consistent. Continued follow-up with a mental health provider, and honest documentation of your symptoms over time, protects you if VA schedules a future reexamination (including the mandatory reexamination tied to the automatic 50% rule). Not every rating gets reexamined; understand when a rating becomes protected from future review (including Permanent and Total status) and what to do if VA proposes to reduce it. See Protect Your Rating and Future Reexaminations for the specifics.

If your PTSD worsens after the initial grant, you can file for an increased rating. See the Rating Increase Guide.
