A service-connected disability can sometimes lead to additional physical or mental health problems over time. When a new condition is caused or worsened by an existing service-connected disability, it may qualify as a secondary service-connected condition.
Veterans may overlook these conditions because they did not begin during military service. However, VA recognizes that disability compensation may also be available for conditions that develop because of an already service-connected disability.
Understanding how secondary service connection works can help veterans identify conditions that may be connected to their current VA benefits.
What Is a Secondary Service-Connected Condition?
A secondary service-connected condition is a new disability linked to a condition that VA has already recognized as service-connected.
The secondary condition does not need to have started during active-duty service. Instead, the evidence must show that an existing service-connected disability caused or aggravated the new condition.
For example, a veteran with a service-connected knee disability may begin walking differently to avoid pain. Over time, that altered gait could contribute to problems in the hip, back, or opposite knee.
A secondary condition may be physical or mental. VA disability compensation can apply to conditions considered related or secondary to disabilities connected to military service.
What Are Some Common Examples of Secondary Conditions?
Secondary conditions vary depending on the veteran’s medical history, treatment, and existing service-connected disabilities.
Examples may include:
- Back or hip problems related to an altered gait from a knee, ankle, or foot disability
- Nerve pain caused by a service-connected spinal condition
- Depression or anxiety related to chronic pain or physical limitations
- Sleep problems connected to pain, tinnitus, or a mental health condition
- Medication side effects that cause or worsen another health problem
- Problems in one joint caused by overcompensating for an injured joint
- Headaches associated with another service-connected condition
These are only examples. Having one of these conditions does not automatically establish secondary service connection. The medical evidence must support the relationship between the service-connected disability and the new or worsened condition.
Can Aggravation Qualify as Secondary Service Connection?
Yes. A service-connected disability does not always need to be the original cause of the secondary condition.
Secondary service connection may also apply when an existing service-connected disability makes another condition worse.
For example, a veteran may already have a non-service-connected back condition. If a service-connected knee disability changes the veteran’s gait and worsens the back problem beyond its natural progression, the veteran may be able to seek benefits based on aggravation.
The evidence should help distinguish the condition’s earlier severity from the additional impairment associated with the service-connected disability.
What Evidence Is Needed for a Secondary VA Claim?
VA describes a secondary service-connected claim as a claim for a new disability linked to a service-connected disability the veteran already has. Supporting evidence generally needs to show the new condition and the connection between the two disabilities.
Helpful evidence may include:
- VA and private medical records
- Diagnostic testing or imaging
- Treatment records showing when symptoms began
- Medication and side-effect records
- Statements from medical providers
- A medical opinion explaining how the conditions are connected
- Lay statements describing changes in symptoms or daily functioning
The evidence should clearly identify the current condition and explain whether the service-connected disability caused or aggravated it.
A diagnosis alone may not be enough. Medical records should explain the connection rather than simply showing that both conditions exist at the same time.
Why Is a Medical Opinion Important?
A medical opinion can help connect the secondary condition to the disability that VA has already recognized.
A helpful opinion may discuss:
- The veteran’s service-connected disability
- The new or worsened condition
- Relevant treatment records and testing
- When the secondary symptoms began
- How the primary condition or its treatment caused or aggravated the secondary condition
- The medical reasoning supporting the provider’s conclusion
For example, a provider may explain how an abnormal gait placed additional strain on the veteran’s lower back. In another case, a provider may describe how medication used for a service-connected condition caused ongoing digestive or neurological symptoms.
The strength of the explanation matters. A conclusion without supporting medical reasoning may not fully show VA why the conditions are connected.
Can Medication Side Effects Be Secondary Conditions?
Potentially. Medication prescribed for a service-connected disability may sometimes cause or worsen another diagnosed condition.
For example, medication used to control pain, inflammation, or a mental health condition may lead to additional symptoms or health complications. The specific relationship must be supported by medical evidence.
Veterans should tell their healthcare providers about side effects and make sure those symptoms are documented. They should not stop or change prescribed medication without first discussing it with a qualified medical professional.
How Do Veterans File a Secondary Claim?
Veterans can file a secondary service-connected claim as part of the VA disability claims process. VA identifies this as a claim for a new disability linked to an existing service-connected disability.
When filing, clearly identify:
- The new condition being claimed
- The existing service-connected disability
- How the two conditions are related
- The medical evidence supporting that relationship
VA may also schedule a Compensation and Pension examination to evaluate the secondary condition and its possible connection to the existing disability.
It is important to describe the full medical history accurately, including when symptoms began and how they have changed.
What If VA Denies a Secondary Condition?
A denial does not necessarily mean that the conditions are unrelated. VA may have found that the evidence did not adequately establish the diagnosis, the connection between the conditions, or the extent of aggravation.
Read the decision letter carefully to understand the reason for the denial.
Depending on the circumstances, a veteran may be able to submit new and relevant evidence through a Supplemental Claim, request a Higher-Level Review, or appeal to the Board of Veterans’ Appeals.
Additional medical records or a more detailed medical opinion may help address an evidence gap, but the appropriate review option depends on the specific decision and the evidence available.
Understanding Secondary Conditions Can Protect Your Benefits
Veterans may focus only on the condition originally connected to their service and overlook additional health problems that developed later.
Recognizing a possible secondary condition can help ensure that VA considers the full effect of a veteran’s service-connected disabilities, including complications caused by treatment, chronic pain, altered movement, or worsening physical and mental health.
