You qualify as a disabled veteran when three things are true at once: you served in the active military, naval, air, or space service; you were discharged under conditions other than dishonorable; and the Department of Veterans Affairs has linked a current physical or mental condition to that service. That link, called service connection, is expressed as a disability rating from 0 to 100 percent, and it is the rating that determines your monthly compensation and the other benefits you can access.
Qualifying Service and Discharge
Before the VA looks at any medical evidence, you have to clear two threshold requirements.
The first is qualifying service. Federal law defines a veteran as someone who served in the active military, naval, air, or space service.1eCFR. 38 CFR 3.1 – Definitions Full-time active duty counts. So does active duty for training when you became disabled from a disease or injury during it, and inactive duty training when you were disabled from an injury or certain cardiac events.2Office of the Law Revision Counsel. 38 USC 101 – Definitions That last category is what pulls in National Guard and Reserve members hurt during a drill weekend or annual training.
The second is your discharge. Honorable and general (under honorable conditions) discharges qualify without question. An other than honorable discharge triggers a formal VA character-of-discharge review before benefits can be granted. A 2024 final rule broadened access in that category by adding a “compelling circumstances” exception, under which the VA weighs whether mental health conditions, combat hardship, sexual trauma, or similar factors influenced the misconduct behind the discharge, and resolves close calls in the veteran’s favor.3Federal Register. Update and Clarify Regulatory Bars to Benefits Based on Character of Discharge A dishonorable discharge from a general court-martial is a permanent bar to VA disability compensation.4Veterans Benefits Administration. Character of Discharge
A Current Disability Connected to Your Service
Meeting the service and discharge tests puts you in the door. What actually makes you a disabled veteran, in the VA’s sense, is a current condition the agency has tied to your service. The VA recognizes several ways that tie can be made, and the one that fits your situation shapes the evidence you need.
Direct Service Connection
This is the straightforward path. You show that a specific injury, disease, or event happened during your active service and that your current disability resulted from it. The regulation requires the facts to demonstrate a particular injury or disease resulting in disability was incurred during service, or, if it existed before service, was made worse by it.5eCFR. 38 CFR 3.303 – Principles Relating to Service Connection A back injury from a training accident, hearing loss from weapons fire, or PTSD from a combat deployment fit here. You need a documented in-service event, a current diagnosis, and a medical opinion tying the two together.
Presumptive Service Connection
For certain conditions tied to specific service locations or hazards, the VA presumes the link. If you served in a qualifying place during a qualifying period and later develop a listed disease, you don’t have to prove causation.6eCFR. 38 CFR 3.307 – Presumptive Service Connection for Chronic, Tropical, or Prisoner-of-War Related Disease Agent Orange presumptions cover Vietnam-era service in Vietnam, Thailand, and several other locations, and include conditions such as Type 2 diabetes, ischemic heart disease, and certain cancers. Contaminated water presumptions apply to veterans who served at Camp Lejeune for at least 30 days between August 1953 and December 1987. The PACT Act expanded these presumptions considerably, and it is worth its own section below.
Secondary Service Connection
If a new condition develops because of a disability the VA already rates as service-connected, the new condition can qualify too. A common example: a veteran with a service-connected knee injury develops chronic back problems from years of walking with an altered gait. You need medical evidence showing the new condition was caused or worsened by the already-rated one.7Veterans Affairs. Evidence Needed for Your Disability Claim
Aggravation of a Pre-Existing Condition
If you entered the military with a condition that got worse during service beyond its natural progression, the VA owes you compensation for the amount of worsening. The regulation presumes any increase in disability during service was caused by service. To deny the claim, the VA has to produce clear and unmistakable evidence that the worsening was due to the condition’s natural course, which is a hard bar to clear.8eCFR. 38 CFR 3.306 – Aggravation of Preservice Disability
The PACT Act and Toxic Exposure
The PACT Act, signed in 2022, is the largest recent expansion of who qualifies. If you deployed to Southwest Asia, served near burn pits, or were exposed to Agent Orange outside Vietnam, it likely reaches your situation. The law added more than 20 presumptive conditions and expanded the list of qualifying service locations.9Veterans Affairs. The PACT Act and Your VA Benefits
Presumptive cancers now include brain cancer, glioblastoma, gastrointestinal cancer, kidney cancer, lymphoma, melanoma, pancreatic cancer, and reproductive and respiratory cancers. Added respiratory illnesses include asthma diagnosed after service, COPD, chronic bronchitis, chronic sinusitis, pulmonary fibrosis, and constrictive bronchiolitis, among others.9Veterans Affairs. The PACT Act and Your VA Benefits
The qualifying locations cover broad ground. Veterans who served on or after August 2, 1990, in Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, or the UAE are presumed to have had toxic exposure. The same applies to service on or after September 11, 2001, in Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, or Yemen. The law also extended Agent Orange presumptions to veterans who served on U.S. or Royal Thai military bases in Thailand from 1962 through 1976, and to service in Laos, Cambodia, Guam, American Samoa, and Johnston Atoll during specified date ranges.9Veterans Affairs. The PACT Act and Your VA Benefits If your service and your condition both appear on these lists, the causal link is already assumed.
What the Disability Rating Means
Once service connection is established, the VA assigns each condition a rating in 10-percent increments from 0 to 100 percent. A 0-percent rating acknowledges the condition is service-connected but finds it isn’t severe enough for monthly compensation. It still opens the door to VA healthcare for that condition. As the rating rises, so does the monthly payment. For a single veteran with no dependents, effective December 1, 2025, monthly compensation runs from $180.42 at 10 percent to $3,938.58 at 100 percent, and veterans rated at 30 percent or higher receive additional amounts for a spouse, dependent children, and dependent parents.10Veterans Affairs. Current Veterans Disability Compensation Rates Compensation is tax-free at the federal level and in all states.
When you have more than one rated condition, the VA does not add the percentages together. It uses a combined ratings table that treats each additional disability as reducing only your remaining healthy capacity. If your first condition is rated 60 percent, the VA considers you 40 percent efficient; a second condition rated 30 percent reduces that remaining 40 percent by 30 percent, leaving you at 28 percent efficiency, or 72 percent combined disability, which then rounds to a final rating of 70 percent.11eCFR. 38 CFR 4.25 – Combined Ratings Table The math consistently produces a combined rating lower than the sum of the individual ones, which surprises many veterans.
The rating also unlocks benefits beyond the check. Even a 10-percent rating gets you no-cost VA healthcare for any condition, prescription coverage for service-connected disabilities, and access to vocational rehabilitation if you have a serious employment barrier. At 30 percent, dependent compensation starts. At 50 percent, all prescriptions become no-cost, not just those for service-connected conditions. At 100 percent with a permanent and total determination, your dependents become eligible for Chapter 35 Dependents’ Educational Assistance and CHAMPVA health coverage, and you gain commissary and exchange privileges.12Veterans Benefits Administration. VA Benefit Eligibility Matrix Many states add property tax exemptions and vehicle registration fee waivers, though the qualifying rating and the benefit vary by state.
Evidence You Need to Prove It
A successful claim rests on three pieces of evidence. Missing any one of them sinks the claim, no matter how strong the others are.
A Current Diagnosis
You need a formal diagnosis from a licensed healthcare provider, and it has to be current. A 15-year-old medical record showing a past condition isn’t enough on its own if no provider confirms you still have it. Without an active diagnosis, the VA has nothing to rate.7Veterans Affairs. Evidence Needed for Your Disability Claim
An In-Service Event or Injury
Your Service Treatment Records are the most direct way to document what happened. If the injury or illness was recorded at the time, that’s strong evidence. Records aren’t the only option, though. Buddy statements, written testimony from fellow service members who witnessed the event, are accepted as lay evidence using VA Form 21-10210. Your own written account carries weight too. The VA weighs the totality of the evidence, not just medical records.7Veterans Affairs. Evidence Needed for Your Disability Claim
A Medical Nexus
The nexus is where most claims live or die. It’s a medical opinion, usually a letter from a doctor, stating that your current condition is “at least as likely as not” connected to your military service. That phrase is the legal standard, meaning a 50-percent or greater probability. A doctor who writes that your condition is “possibly” related to service hasn’t cleared the bar; one who writes “at least as likely as not” has. If the evidence is evenly balanced for and against your claim, the VA has to resolve the tie in your favor under the benefit-of-the-doubt rule.13Office of the Law Revision Counsel. 38 USC 5107 – Claimant Responsibility; Benefit of the Doubt
The VA publishes standardized Disability Benefits Questionnaires designed to collect exactly the medical information the rating process needs. Your private doctor can fill out the appropriate DBQ for your condition and submit it with your claim. A completed DBQ often gives the VA enough information to rate your condition without scheduling a separate exam. The VA doesn’t reimburse the cost of having a private provider complete one. Certain DBQs, including the initial PTSD evaluation form, are restricted to VA clinicians.14Veterans Benefits Administration. Public Disability Benefits Questionnaires (DBQs) – Compensation
Filing and What Happens After
Before submitting a complete claim, consider filing an Intent to File. That step sets a potential effective date for your benefits and gives you a full year to gather evidence and submit the completed application. If the claim is later approved, retroactive payments cover the period back to the date the VA processed your intent to file, not the date you sent the final paperwork.15Veterans Affairs. Your Intent to File a VA Claim If you’re leaving active duty, filing within one year of separation can set the effective date as early as the day after discharge.16Veterans Affairs. Disability Compensation Effective Dates
The application itself is VA Form 21-526EZ.17Veterans Affairs. About VA Form 21-526EZ You can file online through VA.gov, mail the paper form to the VA Claims Intake Center in Janesville, Wisconsin, or hand-deliver documents at a VA regional office. Each method generates a timestamped acknowledgment, which matters for locking in your effective date. Make sure the information on the form, including branch of service, dates of duty, and specific conditions claimed, matches your supporting records. Mismatches are one of the most common causes of processing delays.
After the VA receives your claim, it reviews the evidence and decides whether it can rate the claim as filed. If not, it will schedule a Compensation and Pension exam. The regulation requires that examination when the evidence includes a current diagnosis and an in-service event but lacks enough medical evidence to decide.18eCFR. 38 CFR 3.159 – Department of Veterans Affairs Assistance in Developing Claims The C&P exam is not treatment. The examiner reviews your file, asks about your symptoms, and performs a focused assessment of severity. The report directly shapes your rating, so attend the exam and be thorough and honest about how your conditions affect your daily life. As of February 2026, the VA’s average processing time for disability-related claims is 76.6 days, with complex cases taking longer.19Veterans Affairs. The VA Claim Process After You File Your Claim If the decision denies your claim or assigns a lower rating than you believe fits, the Appeals Modernization Act gives you three review lanes to challenge it, and you can use different lanes for different issues within the same decision.20Veterans Affairs.
