In order to qualify for VA Disability, a condition must be service-connected. But what if a serious condition develops that doesn’t fulfil the normal requirements for service-connection? Enter the VA Presumptive List.
Conditions that cannot be proved service-connected are denied benefits. Over time, however, the VA began noticing patterns in the types of conditions to develop in veterans who had served in similar circumstances. In other words, a significant number of vets who served in the same place at the same time developed similar conditions in a similar time frame.
Since these conditions were not diagnosed while in the military or do not meet the other requirements for service-connection, they technically cannot be considered service-connected. With the number of vets developing these conditions, however, the VA decided that the evidence was too solid to be coincidental. Military service likely caused those conditions. So, the VA created their VA Presumptive List.
The VA “presumes” that any condition on the VA Presumptive List was caused by military service even though there may be no medical reasoning that definitively proves this connection.

The VA Presumptive List basically states that if veterans who served in X location/circumstances during certain years developed Y or Z conditions, then those conditions will be automatically considered service-connected. No proof is needed beyond documents showing that the vet was indeed in that location/circumstance at that time.
All veterans are required to have served at least 90 days of active, continuous service for their conditions to qualify unless it is specifically noted otherwise below.
All conditions on the VA Presumptive List will be considered service-connected UNLESS there is clear evidence indicating that it was not caused by service. For example, a brain hemorrhage that develops within 1 year after leaving the military is normally presumed connected. If, however, the brain hemorrhage was caused by injury to the head from a car accident 3 months after discharge, then it is not service-connected.
Some of the conditions on the VA Presumptive List are required to be a certain seriousness within a certain amount of time (i.e. “manifest to at least 10% within 1 year of exposure”). This means that the condition must meet the requirements for a 10% rating under its code within 1 year of exposure.
For example, if a vet exposed to Agent Orange develops the skin condition porphyria cutanea tarda, the condition must manifest to 10% within 1 year of the last date of exposure. Porphyria cutanea tarda is a condition that causes blisters to form. It is rated under code 7815. To qualify for a 10% rating under this code, the blisters must cover between 5 and 20% of the skin. If less than 5% of the skin is affected within the 1-year period, then the condition does not qualify and is not considered service-connected.
For conditions that have these time restrictions, there may be cases where the condition is not officially diagnosed until after the time limit. If there is enough medical proof to show that the symptoms required for a 10% rating were present before the time limit even though the condition had not been officially diagnosed, it does still qualify.
Many of these conditions are not in the VASRD and so have to be rated analogously on the condition that is closest. The codes we’ve listed are the most likely codes for these conditions to be rated under, but they are not the only option. The Rating Authorities may choose a different code depending on the exact symptoms.
If any of the following chronic diseases are manifest to 10% or more within the first year (there are a few exceptions noted below) after a vet is discharged from the military, then they are automatically considered caused by military service and eligible for VA Disability.
The term “chronic” is used loosely here. Any of these diseases will be considered Chronic unless it was suddenly caused by something clearly not related to military service.
There are quite a few of these diseases on the VA Presumptive List, so we’ve organized them by body system. Just click on the code number to be taken to a discussion about the disease and how it is rated.

If a veteran served in a tropical location and later developed a tropical disease known to come from that location, it can be considered service-connected as long as it manifests to 10% within 1 year of serving in the tropical location.
Now some of the diseases on this VA Presumptive List have incubation periods (the time between infection and the manifestation of symptoms). If the disease is medically known to have such a lengthy incubation period that the symptoms don’t begin until after the 1-year limit, it is still considered service-connected.
Prisoners of War (POWs) get the conditions on the following VA Presumptive List regardless of how long they were on active service. The 90-day rule does not apply. The only factor that determines qualification is the length of time imprisoned. For some conditions, the vet must have been a POW for at least 30 days. For the rest of the conditions, the vet simply must have been a POW for any length of time.
The following conditions qualify once they manifest to at least 10% at any time after discharge.
Any length of imprisonment:
Imprisonment of 30 days or more:
The herbicide Agent Orange was used in both Vietnam and Korea during the 60s and 70s. There are various locations and types of service that could have exposed a veteran to Agent Orange.
Any length of service is enough to qualify—the 90-day rule does not apply to vets exposed to Agent Orange.

Reservists
Reservists can qualify for Agent Orange exposure if they performed flight, ground, or medical crew duties at
Agent Orange Conditions
The following conditions on the VA Presumptive List for Agent Orange qualify if they manifest at any time to any degree unless otherwise specified.
*These three conditions were added in January 2021.
**These two conditions were added on August 10, 2022.
Veterans who qualify as being exposed to radiation include vets who did one of the following while in the military:
The following conditions qualify if they are manifest at any time to any degree:
Persian Gulf War veterans are veterans who served anytime from August 2, 1990 to the present in Southwest Asia, including
The VA Presumptive List for Persian Gulf veterans is divided into three: Gulf War Syndrome, Multi-Symptom Illnesses, and Infectious Diseases. These conditions are considered service-connected if they develop any time during or after Gulf War service.
Gulf War Syndrome
The first VA Presumptive List is by far the most ambiguous.
After the Gulf War, many Gulf War vets began developing seemingly random, unconnected chronic symptoms that do not comprise a single identifiable diagnosis. Because of this, the term “Gulf War Syndrome” was coined to mean a group of unrelated, but disabling, symptoms that many Persian Gulf veterans developed after serving in Southwest Asia. If a clinical diagnosis can be made, then the symptoms do NOT constitute Gulf War Syndrome.
To be included under the heading of Gulf War Syndrome, each symptom must be present or reoccurring for at least 6 months (“chronic”), and cannot be tied to service outside Southwest Asia or be caused by the vet’s misconduct.
Gulf War Syndrome symptoms can include:
Visit our Gulf War Syndrome page for specifics on rating qualifying symptoms.
Multi-Symptom Illnesses
The second VA Presumptive List covers Multi-Symptom Conditions with no known cause. These are conditions that present a much higher level of disability than is medically justified due to lack of clinical findings to explain the severity of symptoms. Conditions with known or partially-known causes do not qualify.
Like with Gulf War Syndrome, these conditions must be Chronic.
Multi-Symptom Illnesses include:
Infectious Diseases
For the final VA Presumptive List for Gulf War Veterans, veterans who develop one of the following infectious diseases qualify if they served in Southwest Asia or Afghanistan after September 19, 2001, unless there is sufficient evidence that the disease was not related to service.
All diseases must be manifest to 10% within 1 year of the veteran’s discharge date unless otherwise noted.
Many of these infectious diseases can cause other symptoms or conditions to develop over time. If a Gulf War veteran who qualifies for one of the above infectious diseases develops one of the following symptoms tied to that disease, it can also qualify for VA Disability. The symptom must, however, develop within the time specified below or, if no time is specified, be satisfactorily connected to the infectious disease by a medical authority.
Brucellosis:
Compylobacter jejuni:
Coxiella burnetii:
Malaria:
Tuberculosis:
Nontyphoid Salmonella:
Shigella:
Visceral Leishmaniasis:
West Nile Virus:
A veteran qualifies under the VA Presumptive List for Mustard Gas and Lewisite Exposure if they can prove full-body exposure to mustard gas (sulphur or nitrogen) or Lewisite while on active duty in one or more of the following ways:
If the veteran qualifies, then the following conditions are considered service-connected.
Mustard gas:
Lewisite:
The key to this VA Presumptive List is the ability to prove exposure. Unfortunately, proper record keeping regarding mustard gas exposure, especially for service members used for testing, was incredibly bad, so the majority of exposure cases were not sufficiently recorded.
Because of this, the VA has a few things in place to help veterans prove exposure. The first is a database of all the names they could compile of service members involved in testing. Again, because of the bad record keeping, this list is far from complete. After receiving a claim, they will check to see if the veteran is on this list. If they are, then that is sufficient to prove exposure. If, however, they are not, then details of the veteran’s case are forwarded to the Deployment Health Directorate for review and determination of exposure. The Directorate has the final say on whether or not the evidence is sufficient to prove exposure.
To make sure that the Directorate has all the information needed to make a proper determination, include the following in your VA Disability Claim:
If a veteran (including reservists and National Guard members) served at Camp Lejeune for at least 30 days between August 1, 1953 and December 31, 1987 and later developed one of the following diseases, it will be considered service-connected as of March 14, 2017.
Veterans who served in the qualifying locations below during the specified time periods will be presumed to have been exposed to the following airborne particulates:
To qualify for the conditions listed below, a veteran must have served in the following locations during the specified time:
For these veterans, if any of the following conditions develop anytime after the veteran’s date of discharge, it will be considered service-connected as of August 5, 2021.
Also for these veterans, if any of the following conditions develop anytime after the veteran’s date of discharge, it will be considered service-connected as of April 26, 2022.
To qualify for the conditions listed below, a veteran must have served in the following locations during the specified time:
For these veterans, if any of the following conditions develop anytime after the veteran’s date of discharge, it will be considered service-connected as of August 10, 2022.
Exposure to asbestos occurred for many service members, but was rarely ever documented. The VA will compensate veterans for asbestos-related conditions (like asbestosis, mesothelioma, etc.) no matter when they develop as long as the veteran can provide sufficient evidence of asbestos exposure.
To claim a condition caused by asbestos exposure, a veteran must submit all of the following:
The VA will consider a veteran to have probable asbestos exposure while in service if they worked in the following fields or with the following materials:
If none of the above applies, a veteran may still be able to claim asbestos exposure if they can provide sufficient evidence supporting probable in-service exposure. This evidence can come from the veteran’s service records, service medical records, and other official sources. Buddy letters from credible witnesses can provide additional testimony of exposure.
Secondary conditions are conditions that are caused by another service-connected condition, like a Traumatic Brain Injury (TBI).
All secondary conditions of TBI can be service-connected as long as they are clearly proven to be the direct result of the TBI. This burden of proof can sometimes be difficult, however, so the VA has made a list of 5 conditions that are automatically considered secondary to TBI if they meet the following criteria:
If your secondary condition qualifies to be rated under TBI, it is rated on the TBI Rating System.
