Hi veterans, Brian Reese here with VA Claims Insider, and in this Ultimate Guide, I’m going to reveal and explain the Top 100+ VA Disability List of Secondary Conditions.

Although this list is not exhaustive, we tried to stick with the most common VA secondary conditions for secondary service connection.

You’ll also learn about VA secondary conditions as well as HOW to get your secondary VA claims service connected so you might become eligible for VA disability benefits under the law.

But first, let’s explore the five (5) types of service connection, keeping in-mind the focus of this post, which is secondary service connection and service connection by aggravation.

5 Types of VA Service Connection for Service Connected Disability Benefits

5 Types of VA Service Connection

#1. Direct Service Connection

This is the most common method of service connection for VA disability compensation benefits. You’re telling the VA that your current disability condition is the direct result of your active duty military service. Maybe it was a training incident, car accident, combat deployment, stress from the job, or other in-service incident, injury, event, or disease that directly caused or made your current disability condition worse. An example is combat PTSD due to constant rocket and mortar attacks in Afghanistan. The PTSD is due to your combat deployment, which is directly related to your military service.

#2. Secondary Service Connection

In accordance with 38 CFR § 3.310 current disability condition that is proximately due to or the result of a service-connected disease or injury shall also be service connected. Let’s say, for example, you contracted tinnitus while serving. Today, even though you are no longer serving, that service-connected tinnitus might be causing migraine headaches, anxiety, and/or depression. Service connection on a secondary basis requires a “showing of causation.” Instead of proving that your disability is directly service-connected, you’ll need to prove that it’s caused or made worse by a different disability (which is service-connected). In this example, you could file a VA disability claim for migraine headaches secondary to your service-connected tinnitus. Secondary Service Connection and related conditions that can be secondary VA claims are the primary focus of this eBook!

Pro Tip: A medical nexus letter is highly recommended to help you prove secondary service connection under the law. >> Click HERE NOW << to sign up for our premier education-based Coaching/Consulting program VA Claims Insider Elite, start free today, connect with a Veteran Coach in minutes, and get high-quality Nexus Letters at reduced rates (if wanted and warranted by the evidence of record).

#3. Presumptive Service Connection

If your disability condition meets certain criteria (set forth by Congress), then your disability condition will be presumed to have been caused by service. Examples include certain chronic debilitating diseases, diseases specific to radiation exposure, diseases associated with herbicide agents (to include Blue Water Veterans), Persian Gulf War Veterans, and Camp Lejeune Veterans. (38 CFR § 3.309 discusses diseases subject to presumptive service-connection in more detail.)

Pro Tip: While you are not required to provide a “Nexus” to establish presumptive service connection, it’s highly recommended that you at least write a personal statement as to WHY you think your disability meets the legal requirements for presumptive service connection. You might want to obtain a medical nexus letter as well.

#4. Service Connection by Aggravation

Sometimes a pre-existing condition is worsened by military service. For example, a veteran may have had flat feet prior to entering service but wearing military boots and prolonged standing worsened his or her flat feet leading to a painful disability called plantar fasciitis, which is eligible for compensation under the law. Additionally, if a veteran has a service-connected knee condition that aggravates a non-service-connected back condition, they could get service connection for their back based on aggravation—provided they can prove that their condition was worsened beyond its natural progression by military service.

#5. Service Connection by 38 U.S.C 1151

This refers to disabilities or death that result from “hospital care, medical or surgical treatment, or examination” by a VA medical professional or facility, or due to participation in a program of vocational rehabilitation. In my experience, this type of service connection is uncommon.

What is VA Secondary Service Connection?

What is VA Secondary Service Connection?

In accordance with 38 CFR § 3.310 disabilities that are proximately due to, or aggravated by, service-connected disease or injury, a current disability condition, which is proximately due to or the result of a service-connected disease or injury shall be service connected.

Service connection on a secondary basis requires a “showing of causation.”

A showing of causation requires that the secondary VA disability claim is “proximately due to” or “aggravated by” another service-connected disability.

There are three key elements that must be satisfied to prove VA secondary service connection under the law:

  • A medical diagnosis of the secondary VA disability you’re attempting to link to the current service connected disability (must be documented in a medical record) AND
  • A current service-connected primary disability (e.g., your current list of service connected disabilities from your account) AND
  • Medical nexus evidence establishing a connection between the service-connected primary condition AND the current disability you’re trying to connect secondary (e.g., Migraines, Sleep Apnea, GERD, IBS, Erectile Disfunction / Female Sexual Arousal Disorder, Radiculopathy, etc.)

The FIRST part can be satisfied with any existing medical evidence in service treatment records, VA medical records, or any private medical records.

The SECOND part can be satisfied with a veteran’s existing service-connected disability rated at 0% or higher.

The THIRD part, and often the missing link needed to establish secondary service connection, can be satisfied with a credible Medical Nexus Letter (Independent Medical Opinion) from a qualified medical provider.

Did you know there are HUNDREDS of common secondary VA claims that you can get service connected by law?

But here’s the brutal truth…

You could be missing out on thousands of dollars of tax-free disability compensation you deserve by law, and not even realize that your current VA disability might be caused or aggravated by an existing service connected disability.

Pro Tip: A Nexus Letter is HIGHLY RECOMMENDED to help establish secondary service connection.


Because “Medical Nexus Evidence” is needed to satisfy the third evidentiary element that must be satisfied to prove your secondary VA claim on an “at least as likely as not” basis.

Can VA Secondary Conditions Be Service Connected?

Can VA Secondary Conditions Be Service Connected

Yes, secondary conditions qualify for service connection, and include any of the 900+ VA disability list of secondary conditions in CFR Title 38, Part 4, the Schedule for Rating Disabilities that can be service connected SECONDARY to a current VA disability you’re already rated for at 0% or higher.

For example, let’s say you’ve got Tinnitus service connected at 10%, but because of the severity of your Tinnitus, you’ve developed Migraine Headaches.

You can open a new VA claim on the website, and file a claim for Migraines Secondary to Tinnitus, and get service connected and rated at 0%, 10%, 30%, or 50% for your Migraine (Headaches), depending on the Frequency, Severity, and Duration of your symptoms as well as how your symptoms negatively affect your work, life, and/or social functioning.
