If you’re a veteran exploring VA disability benefits, you’ve likely heard two terms: “PACT Act” and “Presumptive Condition.”

Understanding what these mean is one of the most important things you can do for your health and your medical documentation. The PACT Act is the biggest expansion of veteran benefits in decades, and it’s built around the concept of “presumptive service connection.”

This guide breaks down what a presumptive condition is from a medical standpoint and what the PACT Act presumptive list includes.

What is a “Presumptive Condition”?

Normally, for a medical professional to establish a service connection in a nexus letter, they look for three things:

1. A current clinical diagnosis of a disability.
2. An event, injury, or illness documented in your service records.
3. A medical “nexus” (link) that connects #1 and #2 based on clinical judgment.

A presumptive condition is a legal category where the VA assumes the link between service and the condition exists without requiring an individual nexus letter for that specific connection.

If you have a condition on a “presumptive list,” and you served in a specific location during a specific time, it is presumed that your service caused your condition. In these cases, medical documentation focuses on (1) an accurate current diagnosis and (2) evidence of service in a qualifying location.

The PACT Act: A Massive Expansion of Presumptive Conditions

The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics (PACT) Act became law in 2022. It adds more than 20 new presumptive conditions for veterans exposed to burn pits, Agent Orange, and other toxic substances.

This law allows millions of veterans, especially those who served in the Gulf War and post-9/11 eras, to seek medical evaluations for these conditions with the understanding that service connection is presumed by the VA.

PACT Act Presumptive Lists

The PACT Act covers three main groups.

1. Burn Pit & Toxic Exposure (Gulf War & Post-9/11)

If you served in any of these locations on or after August 2, 1990:

• Iraq, Afghanistan, Syria, Saudi Arabia, Kuwait, Qatar, UAE, Bahrain, Oman, Uzbekistan, Djibouti, Egypt, Jordan, Lebanon, Yemen.

You are eligible for presumptive connection for the following conditions:

Cancers:

• Brain cancer
• Gastrointestinal cancer (of any type)
• Glioblastoma
• Head cancer (of any type)
• Kidney cancer
• Lymphoma (of any type)
• Melanoma
• Neck cancer (of any type)
• Pancreatic cancer
• Reproductive cancer (of any type)
• Respiratory (breathing-related) cancer (of any type)

Respiratory and Other Illnesses:

• Asthma (if diagnosed after service)
• Bronchitis (chronic)
• Bronchiolitis (constrictive or obliterative)
• COPD (chronic obstructive pulmonary disease)
• Emphysema (chronic)
• Granulomatous disease (chronic)
• Interstitial lung disease (ILD)
• Pleuritis (chronic)
• Pulmonary fibrosis
• Rhinitis (chronic)
• Sarcoidosis
• Sinusitis (chronic)

2. Agent Orange Exposure (Vietnam & Other Areas)

The PACT Act added two new conditions to the Agent Orange presumptive list:

1. High blood pressure (hypertension)
2. Monoclonal gammopathy of undetermined significance (MGUS)

This is in addition to the existing list, which includes conditions like Type 2 Diabetes, Parkinson’s disease, Ischemic Heart Disease, and various cancers (like Prostate Cancer and Respiratory Cancers).

3. Camp Lejeune Water Contamination

If you served or lived at Camp Lejeune or MCAS New River for at least 30 total days between August 1, 1953, and December 31, 1987, you are eligible for presumptive connection for conditions such as Adult leukemia, Bladder cancer, Kidney cancer, and Parkinson’s disease. Clinical documentation of these conditions is vital for your medical records.

Medical Services and Documentation for PACT Act Conditions

1. Obtain a Clinical Diagnosis: To seek benefits for a presumptive condition, you must have a current diagnosis from a medical professional. Our services include independent medical evaluations to document your symptoms, diagnoses, and any functional limitations.
2. Review Medical Evidence: While the VA presumes service connection for the list above, having a thorough clinical record helps ensure your medical file accurately reflects your health status. For conditions not on the presumptive list, we provide nexus letters based solely on independent clinical judgment to document the link between your condition and service.

Our fees are for medical services only and are never contingent on the outcome of a VA claim. We comply fully with SB 694 and focus exclusively on providing high-quality medical evidence and clinical evaluations for veterans.
