Why a PTSD Nexus Letter Can Be Critical for Your VA Disability Claim? If you’re a veteran seeking VA disability benefits for post-traumatic stress disorder (PTSD), you may already know the VA requires credible medical evidence linking your PTSD to your military service to approve your claim. This is where a PTSD nexus letter becomes a powerful tool in your pursuit of the benefits you have earned.
At Attain Med Group, we help veterans simplify the VA claims process by connecting them with independent medical providers who specialize in writing detailed, accurate nexus letters for PTSD and other conditions, ensuring your case is presented clearly and professionally to the VA.
What Is a PTSD Nexus Letter? A PTSD nexus letter is a detailed, medically sound statement from a qualified mental health professional that clearly connects your PTSD diagnosis to specific in-service events, stressors, or your overall time in service.

This letter typically includes:
- A review of your medical and service records.
- Confirmation of your PTSD diagnosis.
- A clear statement using VA-accepted language, such as “it is at least as likely as not” that your PTSD is related to your service.
- Medical rationale explaining why your service contributed to or caused your PTSD.
Why Is a PTSD Nexus Letter Important?
Even if you have a PTSD diagnosis, the VA will not grant benefits unless they see clear medical evidence linking your condition to your service. Many veterans face denials because:
- The VA Claims There Is “No Service Connection.”
The VA often states:
“We acknowledge your PTSD diagnosis, but we do not see evidence it is related to your military service.”
This happens frequently if your claim lacks a medical opinion explicitly connecting your PTSD to specific in-service stressors or service conditions.
- Service Records Do Not Explicitly Document PTSD-Related Events
PTSD often results from combat exposure, military sexual trauma (MST), or witnessing traumatic incidents during service. However:
- Many veterans do not report these events due to stigma or fear of reprisal.
- Command or unit documentation of traumatic events may not exist.
- Service records often focus on operational details, not individual emotional or mental health responses.
Without documentation, the VA may argue that there is no evidence tying your PTSD to your service, even if the connection is clear to you and your healthcare providers.
- The Veteran Did Not Seek Treatment During Service
It is extremely common for veterans not to seek mental health treatment while on active duty due to:
- Fear of jeopardizing their career.
- Concerns about stigma and being perceived as “weak.”
- Lack of awareness about PTSD symptoms until after discharge.
The absence of in-service treatment records is frequently used by the VA to deny PTSD claims, citing “no medical evidence of treatment during service.”
How a PTSD Nexus Letter Helps

Example:
A veteran exposed to IED blasts during deployment develops hypervigilance, nightmares, and anxiety after discharge but has no in-service treatment. A nexus letter can explain:
- The correlation between the veteran’s deployment environment and PTSD symptoms.
- Why the veteran did not seek treatment during service.
- How the current PTSD symptoms are consistent with the traumatic events experienced in service.

- Service treatment records.
- DD214 and service history.
- Medical and mental health treatment records (VA and private).

A strong PTSD nexus letter should:

- Explain how your in-service events contributed to your PTSD.
- Reference specific symptoms, diagnoses, and treatment history.
- Be signed by a qualified professional with appropriate credentials.
5️⃣ Submit the Nexus Letter with Your Claim or Appeal
Attach your PTSD nexus letter when:
- Filing an initial VA disability claim.
- Appealing a denial or low rating.
- Submitting new evidence during an open claim.
PTSD Nexus Letter vs. VA C&P Exam Opinion
Many veterans confuse the C&P exam with a nexus letter.

While the VA heavily relies on C&P exams for claim decisions, a nexus letter can challenge or support C&P findings with detailed evidence, strengthening your claim.
