No, you don’t need a Nexus Letter for presumptive conditions.
Why?
Because a presumptive disability condition does not have a specific “Nexus” requirement under the law.
In fact, the VA “presumes” your disability is automatically connected to your military service, assuming you meet the other requirements for presumptive service connection.
Okay, let’s explore VA presumptive conditions in more detail.
What is a VA Presumptive Disability?
A VA presumptive disability is one that the VA “presumes” to be service connected, even if there’s no specific “Nexus” for service connection.
Here’s how presumptive disability works:
If you served at X location during the qualifying period and developed Y condition as a result, then X + Y = automatic service connection.
Instead of having to prove a service-connected disability, you only need to show on your DD 214 that you were in an eligible location during a specific period and that you developed a qualifying condition as a result.
We also recommend you write and submit a strong personal Statement in Support of a Claim.
Buddy letters can also be helpful in filling in any gaps in service or personnel records; make sure your buddy statements are from first-hand witnesses.

What are the VA Presumptive Eligibility Requirements?
For certain disability conditions, the VA automatically assumes (“presumes”) that your military service caused your condition.
If you have a presumptive VA disability condition, you don’t need to prove that your service caused the condition.
You only need to meet the service requirements for presumption.

Do I Need a Nexus Letter for Presumptive Conditions?
No, Nexus Letters are not necessary for presumptive VA disability.
Why?
Because presumptive disabilities do not have a specific “Nexus” requirement under the law.
The VA “presumes” your disability is automatically connected to your military service, assuming you meet the other requirements for presumptive service connection.
What is the VA Regulation on Presumptive Service Connection?
According to the VA’s M21-1, “Diseases or conditions subject to presumptive service connection will be considered to have been incurred in or aggravated by service if manifested to a compensable level, when required by the corresponding regulation or statute, within the time frame specified for that certain disease under the regulation or statute, even if there is no evidence of such disease during service.”
Translation: A specific “Nexus” is not required to prove presumptive disability.
Here’s a helpful table of presumptive diseases or conditions as well as the appropriate references:
