Today, I’m explaining why The Caluza Triangle is critical to getting your VA disability claim approved.

Before you file a VA claim, it’s important for veterans to understand the evidentiary elements you need to prove to the VA before getting any claim or appeal approved.

What’s the bottom line?

The Caluza Triangle has three key elements necessary for VA claim success.

These three elements are known as the Hickson Elements.

Keep in mind that any disability condition must be medically documented in your records!

Here’s the Caluza Triangle 3-part test:

  • #1. Medical Diagnosis of a Disability Condition (no medical diagnosis; no service connection)
  • #2. Evidence of an In-Service Event, Injury, Disease, or Aggravation
  • #3. Nexus (link between #1 and #2) via Competent Medical Evidence

Read the Caluza vs. Brown Case Below!

What is the Caluza Triangle?

What is the Caluza Triangle

The “Caluza Triangle” came from a U.S. Court of Appeals for Veterans Claims (Court) case called Caluza v. Brown, April 12, 1995, 7 Vet.App. 508 (1995).

The case is important because it established, among other things, a 3-part test a veteran must pass to get VA disability benefits.

Here’s the Caluza Triangle explained using 3 questions:

  • #1. Does the Veteran have a Medical Diagnosis of a Disability Condition in a Medical Record?
  • #2. Does the Veteran have Evidence of an In-Service Event, Injury, Disease, or Aggravation?
  • #3. Does the Veteran Establish a Nexus (link between #1 and #2) via Competent Medical Evidence?

If the answer to all three questions is “YES,” a veterans VA disability conditions shall be service connected.

Pro Tip: The Caluza Triangle and the Hickson Elements are limited to direct service connection only. They do not apply to secondary service connection or presumptive service connection.

The 3 Elements of The Caluza Triangle Explained

Factor #1: Diagnosis of a Current Disability in a Medical Record

Factor #1: Diagnosis of a Current Disability in a Medical Record

First, you must have a medical diagnosis of a current disability in a medical record.

The diagnosis can be in service treatment records, VA medical records, or private medical records to include a DBQ or Nexus Letter.

For example, if you file a claim for PTSD and don’t yet have a diagnosis, your VA claim will be denied.

If you don’t have a diagnosis of the disability you’re filing for, go see your primary care provider or other specialist before applying for VA benefits.

You’ll thank us later!

Factor #2: Evidence of an In-Service Event, Injury, Disease, or Aggravation

Caluza Triangle Factor #2: Evidence of an In-Service Event, Injury, Disease, or Aggravation

Second, you must provide evidence of an in-service event, injury, disease, or aggravation that caused or made your disability worse.

Here’s a quick litmus test to think about: Do you have medical evidence?

If not, you better get some in VA medical records or private treatment records before filing a VA claim.

Your DD 214, a credible Buddy Letter, and/or a Statement in Support of a Claim can all help prove your case, but you still need medical evidence of a current disability.

Again, you need to be thinking of the link or connection between factors #1 and #2.

For example, constant rocket and mortar attacks in Afghanistan might have caused you to fear for your life, and subsequently led to your PTSD.

Or maybe you got injured during a training accident while on active duty and now you have shoulder and neck pain as a result.

Perhaps you entered the military with flat feet, but your military service worsened the condition beyond its natural progression.

“Nexus,” Meaning Link or Connection Between #1 and #2 via Competent Medical Evidence

Finally, there must be a “Nexus” for service connection between factors #1 and #2 above.

If you can’t prove a link or connection between your disability and your military service, you’ll likely get denied VA disability benefits.

There are 5 types of service connection under the law.

What are the 5 Types of VA Service Connection?

What are the 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 an IED attack in Iraq.

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 developed ringing in your ears, called “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.

#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 Burn Pit Exposures, 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 our experience, this is uncommon.

What is Secondary Service Connection?

What Do I Need to Prove for 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.

VA secondary conditions require a “showing of causation.”

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

There are three evidentiary 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 VA.gov account) AND
  • Medical nexus evidence establishing a connection between the service-connected primary condition AND the current disability

VA secondary conditions for secondary service connection include any of the 834 disabilities listed 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.

What Do I Need to Prove for VA Secondary Service Connection?

VA Secondary Service Connection Tips

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

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 private healthcare provider that shows the link or connection between the two disability conditions.

What is a Nexus Letter for Secondary Condition?

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

Here’s the brutal truth veterans…

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 with high probative value is RECOMMENDED to help establish secondary service connection.

Why?

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.

What Do I Need to Prove for Presumptive Service Connection?

What Do I Need to Prove for Presumptive Service Connection

A VA presumptive disability is one that the VA “presumes” to be service-connected, even if there’s no specific Nexus (meaning “link” or “connection”) for service connection.

It is generally easier to prove presumptive service connection, assuming you qualify.

Presumptive disability works like this: If you served at X location during the qualifying period and developed Y condition as a result, then X + Y = automatic service connection.

Instead of having to prove a service-connected disability, you only need to show on your DD 214 that you were in an eligible location during a specific period and that you developed a qualifying condition as a result.

We also recommend you write and submit a strong personal Statement in Support of a Claim.

Buddy letters can also be helpful in filling in any gaps in service or personnel records.
