When Veterans think of VA disability benefits, they often focus on conditions directly caused by military service. But what if a service-connected condition causes another health issue later on? This is where secondary service connection claims come in—a powerful but often overlooked aspect of the VA disability system.
What Is a Secondary Service Connection?
A secondary service connection means a new condition has developed as a result of an already service-connected disability. The VA allows compensation for these secondary conditions if you can prove the link between the two.
For example:
A Veteran with service-connected knee problems develops back pain from years of altered posture or gait.
A Veteran with PTSD develops hypertension due to chronic stress and anxiety.
Diabetes (service-connected) leads to peripheral neuropathy or kidney problems.
In these cases, the original condition may be clearly tied to service, but the secondary condition still impacts daily life and deserves compensation.
Why Secondary Claims Matter
Secondary conditions can significantly worsen your quality of life. Without filing for secondary service connection, you may miss out on benefits you’ve earned. Filing these claims correctly can increase your overall VA rating and monthly compensation.
Key Elements of a Successful Secondary Claim
Medical Nexus
You need medical evidence that clearly connects the secondary condition to the primary one. A doctor’s statement or independent medical opinion (IMO) is often required.
Consistent Documentation
Your claim should be supported by treatment records showing both the primary and secondary conditions. Gaps or inconsistencies can lead to denials.
Detailed Personal Statements
A Statement in Support of Claim can be useful here. Explain how your life has changed and how the secondary condition has developed over time.
Understand Aggravation vs. Causation
Even if the primary condition didn’t cause the secondary condition, it might have aggravated it. For example, if your service-connected back pain worsens your depression, you may still qualify.
Common Secondary Claims Examples
Sleep apnea secondary to PTSD or anxiety
Depression due to chronic pain
Headaches from traumatic brain injury (TBI)
Obesity caused by medication side effects, leading to joint issues or diabetes
Challenges in Secondary Claims
The biggest hurdle is often the nexus letter—a medical opinion linking the two conditions. VA examiners don’t always agree with outside doctors, so it’s important to work with professionals who understand VA standards and can write convincing, evidence-based opinions.
