The VA Disability Hack in Nine Steps

I filed my own VA disability claim. Before I sent it in I spent three years on the rating schedule, the regulations, and thousands of Board of Veterans' Appeals decisions. I kept at it until I knew what the VA actually grants and what it turns down. What came out of that is a nine-step method. This page is the method, in order. Read it first. Everything else on this site hangs off one of these steps.

Step 1. Gather your documents

This is where many veterans stall. You need your service treatment records, your personnel file, your VA treatment records, and records from any private doctor who has seen you for the condition. Start requesting them now, before you file anything.

The VA has a duty to help. Under 38 CFR 3.159(c), it will request federal records like service medical records itself, and it will make reasonable efforts to get private records. But it can only request records you tell it about. You have to say who holds the records, roughly when you were treated, and for what. Do that work up front.

If your service records are thin, do not quit. 38 CFR 3.303(d) allows service connection for a disease diagnosed after discharge when the evidence shows it began in service. And 38 CFR 3.102 says reasonable doubt is resolved in your favor, even without official records. That matters most when the injury happened in combat or under similar conditions, and the injury you describe is the kind those conditions would be expected to cause.

One more thing before you file, and it is the thing almost nobody does: see your own doctor. Ask for a written opinion on each condition. It should say whether the condition is at least as likely as not related to your service, or to a condition the VA already rates. Those exact words matter. The VA calls that a nexus opinion. Under 38 CFR 3.159(a)(1), an opinion from a doctor qualified by education, training, or experience is competent medical evidence, and 38 CFR 3.303(a) requires the decision to be based on review of the entire evidence of record. An opinion from a doctor who examined you, knew your history, and explained the reasoning is what the claim rests on. Ask that doctor to fill out the VA's Disability Benefits Questionnaire for the condition too, if VA publishes one for it, the same form the VA examiner uses, so the measurements that decide your rating are in the file before the VA exam. An adequate private report can be accepted for rating without a VA exam (38 CFR 3.326(c)). If it falls short, the VA orders its own exam (38 CFR 3.326(a)). VA keeps some DBQs off the public list, including hearing loss and tinnitus, initial PTSD, TBI, cold injury, and the Gulf War general medical exam. For those your doctor writes a report and the VA exam supplies the form. Make sure the questionnaire is filled out the way the rating schedule and the Board's case law require. 38 CFR 4.46 calls a goniometer, a tool for measuring angles, indispensable in VA examinations, so ask your doctor to use one. 38 CFR 4.59 says the joint should be tested for pain on active and passive motion, weight-bearing and not. 38 CFR 4.40 and 4.45 require the exam to describe functional loss from pain, weakness, fatigability, and incoordination. The Board, following the Court of Appeals for Veterans Claims (DeLuca v. Brown, Sharp v. Shulkin), also expects the examiner to measure again after repeated use, note where pain begins, and estimate in degrees what a flare-up takes away. A questionnaire that skips the added loss from painful motion, or the active, passive, and weight-bearing testing 4.59 asks for, is the kind of exam the Board calls not adequate for rating purposes, as it did in citation 19143628. The VA may still send you to its own exam. Your doctor's opinion is what that examiner has to reckon with.

Step 2. Find your ratings in 38 CFR Part 4

Veterans claim "back pain." The rating schedule does not rate back pain. It rates lumbosacral strain, diagnostic code 5237 in 38 CFR 4.71a, under the General Rating Formula for the spine. That formula assigns a percentage based on forward flexion measured in degrees, combined range of motion, and whether muscle spasm or guarding is severe enough to cause an abnormal gait.

Once you know the criteria, you know what the exam has to measure. 38 CFR 4.1 requires accurate and fully descriptive examinations. 38 CFR 4.7 says that when your condition falls between two ratings and is closer to the higher one, you get the higher one.

The Claim Map on this site takes each condition to its diagnostic code and lays out the criteria in plain English, level by level.

Step 3. Research secondary conditions

This is the multiplier. 38 CFR 3.310(a) says a disability that is proximately due to or the result of a service-connected condition shall be service connected. 38 CFR 3.310(b) goes further. If a service-connected condition makes a condition that is not service connected worse, the added harm is service connected too. Only the part beyond what the disease would have done on its own counts. And medical evidence has to show how bad the condition was before, either from records made before the worsening started or from the earliest records after it began.

One primary condition often causes more than one secondary condition, and each one can get its own rating. A bad knee changes how you walk and takes the hip and back with it. A spine condition produces radiculopathy, and 38 CFR 4.71a tells the rater to evaluate neurologic abnormalities separately from the spine rating. Years of anti-inflammatories for joint pain damage the stomach.

The Claim Map shows which secondary conditions usually follow from each condition you select.

Step 4. Identify presumptive conditions

A presumption means you do not have to prove the link. You do not have to show the condition came from service. The regulation assumes it did, unless the VA has affirmative evidence that it did not.

38 CFR 3.307 and 3.309 cover the chronic diseases, including arthritis, hypertension, diabetes, and psychoses, if they showed up to a compensable degree within one year of separation. Three diseases on that list get longer. Hansen's disease and tuberculosis have three years, and multiple sclerosis has seven (38 CFR 3.307(a)(3)). They also cover herbicide exposure for service in Vietnam and near the Korean DMZ, former prisoners of war, radiation exposure, and Camp Lejeune water. On herbicides the PACT Act goes further than the regulation, and VA applies it. VA also presumes herbicide exposure for service at any U.S. or Royal Thai military base in Thailand from January 9, 1962 through June 30, 1976, in Laos from December 1, 1965 through September 30, 1969, in Cambodia at Mimot or Krek in Kampong Cham Province from April 16, 1969 through April 30, 1969, in Guam or American Samoa or their territorial waters from January 9, 1962 through July 31, 1980, and on Johnston Atoll or a ship that called there from January 1, 1972 through September 30, 1977. VA lists the places and the dates at va.gov/disability/eligibility/hazardous-materials-exposure/agent-orange/. 38 CFR 3.317 covers Gulf War veterans with undiagnosed illness or chronic multisymptom illness such as fibromyalgia, chronic fatigue syndrome, and functional gastrointestinal disorders. One catch: under 38 CFR 3.317(a)(1)(i) the illness must have appeared either during service in the Southwest Asia theater or to a degree of 10 percent by December 31, 2026, unless VA extends that date again, as it has done repeatedly since 2001. Check the current text on eCFR before you rely on it. 38 CFR 3.320 is the burn pit rule. It covers fine particulate matter, the fine dust and smoke in the air, for service in the Southwest Asia theater during the Gulf War, and for service in Afghanistan, Syria, Djibouti, or Uzbekistan on or after September 19, 2001. Asthma, rhinitis, and sinusitis are presumed service connected if they appear at any time after separation, to any degree. So is a list of rare cancers of the lung, trachea, and larynx. The PACT Act, 38 U.S.C. 1120, goes further than the regulation, and VA applies it. VA also presumes chronic bronchitis, COPD, emphysema, constrictive or obliterative bronchiolitis, granulomatous disease, interstitial lung disease, pleuritis, pulmonary fibrosis, sarcoidosis, and brain, head, neck, gastrointestinal, kidney, pancreatic, reproductive, and respiratory cancers of any type, glioblastoma, lymphoma of any type, and melanoma, for service in Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, Oman, the United Arab Emirates, or Somalia on or after August 2, 1990, and in Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, or Yemen on or after September 11, 2001. VA lists them all at va.gov/resources/the-pact-act-and-your-va-benefits/.

Two newer sections, 38 CFR 3.320a and 3.320b (2025), extend the toxic-exposure presumption to bladder and ureter cancers and to acute and chronic leukemias, multiple myeloma (including MGUS), myelodysplastic syndromes, and myelofibrosis, for service on or after August 2, 1990 in the Southwest Asia theater or Somalia, and on or after September 11, 2001 in Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Yemen, or Uzbekistan. 38 CFR 3.318 presumes ALS appearing at any time after discharge for any veteran with 90 days or more of continuous active service.

Many veterans qualify and do not know it.

Step 5. Read the actual Board decisions

This is the hack itself. The Board of Veterans' Appeals publishes its decisions as plain text files on va.gov. They tell you exactly what evidence won, and what exam mistakes led to a loss.

Take one I read while writing this, citation 1812000, at https://www.va.gov/vetapp18/Files2/1812000.txt. A Vietnam machine gunner claimed hearing loss. Two VA examiners said no because his hearing tests in service were normal. The Board threw both opinions out, one as inadequate and one as contradictory, and granted the claim on a single VA treatment note plus the veteran's own credible statements, resolving doubt under 38 CFR 3.102. Then it returned his back, nerve, skin, and foot claims for new exams, because the examiners had ignored what he told them. The order to the next examiner was blunt:

It is not sufficient to base an opinion on a mere lack of documentation of complaints in the service or post-service treatment records.

That one decision teaches you what a bad exam looks like, why the Board throws one out, and what a winning record contained.

Your playbook links to Board decisions on each condition you choose, sorted by what was granted, what was denied, and the reasons given.

Step 6. Mental health caused by your conditions is real and ratable

This is a rating veterans often overlook. Depression and anxiety caused by any service-connected condition are separate disabilities. In the Board decisions we have indexed, the conditions most often named as the cause are a bad back first, then a bad knee, then tinnitus and hearing loss. Sleep apnea, a brain injury, or a disfiguring scar can do the same thing. They are rated under 38 CFR 4.130, the General Rating Formula for Mental Disorders, under codes such as 9434 for major depressive disorder, 9435 for unspecified depressive disorder, and 9400 for generalized anxiety disorder. The rule that connects them is 38 CFR 3.310. The mental health condition is caused by the service-connected physical one. The regulation's phrase for that is "proximately due to."

The formula rates how much the symptoms get in the way of work and relationships. The schedule calls that occupational and social impairment. Depressed mood, anxiety, and chronic sleep trouble sit at the 30 percent level. Being less reliable and less productive, with swings in motivation and mood, is the 50 percent level. Falling short in most areas of life, including work and family, is the 70 percent level. A mental health rating can end up the largest single rating a veteran holds. Get evaluated.

Step 7. Submit with evidence

A claim is evidence, not a form. 38 CFR 3.159(c)(4) tells you what the VA needs before it will even order an exam. It needs evidence of a current disability, or of symptoms that keep coming back. It needs evidence of an event, injury, or disease in service. And it needs some sign that the current disability may be tied to that event, or to another service-connected disability. Your submission should establish all three on day one: the diagnosis, the in-service event or the primary condition, and a nexus opinion from a doctor who explains the connection.

File the nexus letter, the private records, your personal statement, and the lay statements with the claim.

Step 8. Lay evidence matters

Lay evidence is competent evidence. 38 CFR 3.159(a)(2) defines it: evidence from a person who knows the facts and describes what a layperson can observe. 38 CFR 3.303(a) requires the VA to decide service connection on all pertinent medical and lay evidence. In the decision above, the Board called the veteran's statements credible and sent the exams back because the examiners ignored them.

The people who watched you suffer and chose to support you are your witnesses. Your spouse, your kids, your parents, your battle buddies, your coworkers. Ask them to write what they observed: what you were like before, what they see now, when it started, what a normal day looks like. Specific and dated. Their statements carry the story the medical records leave out.

Step 9. Be honest

This is ethics and strategy at the same time. Your credibility is a single thing. Lose it on one claim and it can cost you the others. In the decision above, the Board's single finding that the veteran was credible carried across every claim in his file, the one it granted and the four it sent back. 38 CFR 3.102 says mere suspicion about your statements is not a reason to withhold the benefit of the doubt. Contradiction by evidence or known facts is. And the benefit of the doubt cannot be used to hide a real conflict in the evidence. Exaggerate at an exam and you contradict your own records and your own witnesses. The VA also treats a knowingly false statement in a claim as fraud under 38 CFR 3.901, which makes exaggeration a worse bet than it looks.

An honest, thorough claim is the better bet. It does not guarantee a grant, but it is the kind of record the Board can grant on. Claim what you actually have and describe it exactly as it is.

Where to go next

Start with Step 1 today. Then open the Claim Map, choose your conditions, and read the decisions linked under each one. This site is education, not legal advice or representation. I am a veteran who did this for himself, not a lawyer or an accredited agent.
