What Veterans Need to Know About Secondary Service Connection 

Many veterans receive VA disability compensation for conditions directly related to their military service. However, what many do not realize is that service-connected disabilities can often lead to additional health problems over time. These conditions, known as secondary conditions, may also qualify for VA disability compensation. 

Understanding secondary service connection can help veterans ensure they are receiving benefits for the full impact of their service-connected disabilities. 

What Is a VA Secondary Condition? 

A secondary condition is a disability that develops as a result of an already service-connected condition. Unlike a primary condition, which is directly linked to military service, a secondary condition is caused or aggravated by a condition that the VA has already recognized as service-connected. 

For example, a veteran with a service-connected knee injury may develop chronic back pain due to an altered gait. Likewise, a veteran with PTSD may later develop sleep apnea, migraines, or hypertension. If medical evidence establishes a connection between the conditions, the VA may grant secondary service connection. 

The VA recognizes secondary service connection under federal regulation 38 CFR § 3.310, which allows compensation for disabilities that are proximately due to or aggravated by a service-connected condition. 

Common Secondary Conditions Veterans Should Know About 

While there is no official VA list of approved secondary conditions, certain relationships between disabilities are commonly seen in successful claims. 

PTSD Secondary Conditions 

Veterans with service-connected PTSD may experience: 

• Sleep apnea 
• Migraines 
• Hypertension 
• Gastroesophageal reflux disease (GERD) 
• Irritable bowel syndrome (IBS) 
• Erectile dysfunction 
• Depression and anxiety disorders 

Tinnitus Secondary Conditions 

Tinnitus is one of the most common service-connected disabilities among veterans. Potential secondary conditions may include: 

• Migraines 
• Anxiety 
• Depression 
• Sleep disturbances 
• Vertigo 

Orthopedic Secondary Conditions 

Joint, back, and musculoskeletal injuries often create additional problems over time. 

Examples include: 

• Hip conditions secondary to knee injuries 
• Back conditions secondary to foot or ankle disabilities 
• Radiculopathy secondary to spinal conditions 
• Opposite knee degeneration caused by altered gait mechanics 

Diabetes Secondary Conditions 

Veterans with service-connected diabetes may develop: 

• Peripheral neuropathy 
• Kidney disease 
• Diabetic retinopathy 
• Erectile dysfunction 
• Cardiovascular complications 

Medication-Related Secondary Conditions 

In some cases, the treatment for a service-connected disability can create additional health issues. 

Examples include: 

• GERD from long-term pain medication use 
• Weight gain associated with mental health medications 
• Sexual dysfunction caused by antidepressants 
• Liver or kidney complications related to prescribed medications 

How the VA Evaluates Secondary Conditions 

The VA generally requires three elements to establish secondary service connection: 

1. A Current Diagnosis

The veteran must have a diagnosed medical condition. 

2. An Existing Service-Connected Disability

There must be a primary condition that is already service-connected, even if it is rated at 0%. 

3. Medical Evidence Linking the Conditions

The veteran must provide evidence showing that the primary condition caused or aggravated the secondary condition. This evidence often comes from medical records, specialist opinions, or a nexus letter from a qualified healthcare provider. 

Can Secondary Conditions Increase Your VA Rating? 

Yes, secondary conditions receive their own disability evaluations and are combined with existing ratings using VA math. Depending on the severity of the secondary condition, a successful claim may significantly increase a veteran’s overall combined disability rating and monthly compensation. 

Many veterans discover that secondary claims provide a more complete picture of how their service-connected disabilities affect their daily lives. 

Common Mistakes Veterans Make 

When filing secondary claims, Veterans often: 

• Fail to obtain a current diagnosis 
• Do not submit medical evidence linking the conditions 
• Rely solely on personal statements 
• Miss evidence showing aggravation of an existing condition 
• Overlook conditions caused by medication side effects 

Because secondary service connection depends heavily on medical evidence, documentation is critical. 

Final Thoughts 

Many service-connected disabilities do not exist in isolation. Chronic pain can lead to depression. PTSD can contribute to sleep disorders and migraines. Orthopedic injuries can create problems throughout the body due to altered movement and compensation. 

Veterans who develop additional health conditions related to a service-connected disability may be entitled to additional VA compensation through secondary service connection. Understanding these relationships and obtaining appropriate medical evidence can make a significant difference in the outcome of a claim. 

If you have developed new symptoms or diagnoses since receiving your original VA rating, it may be worth exploring whether those conditions could qualify for secondary service connection.
