You may have heard of the PACT Act, with PACT standing for Promise to Address Comprehensive Toxics. This 2022 act extends VA compensation and health care to veterans who were exposed to various toxic substances.
The PACT Act was one of the biggest expansions of benefits in VA history. Since it was passed, PACT Act disability claims have been approved at a nearly 75% rate, with more than 1.8 million approved claims at the time of this writing.
The PACT Act may apply to veterans who were exposed to asbestos, jet fuel, toxic water at Camp LeJeune, Agent Orange (the plant-killing chemical used in Vietnam), and burn pits (sites where military waste was burned for disposal), and more.
If you were exposed to toxins while serving in the military, the PACT Act is your lifeline.

Do My Symptoms Qualify Me for PACT Act Compensation?
When you consider all of the toxic substances U.S. troops have been exposed to over the years, you’re looking at a huge spectrum of symptoms. The military has identified hundreds of medical conditions that could be related to toxin exposure.
With some of these conditions, you will need to prove a medical connection or “nexus” between your symptoms and your military service, but other conditions are considered “presumptive” and don’t require this same proof for PACT Act Compensation.
What Are Presumptive Symptoms for the PACT Act?
The military recently updated and expanded its “presumptive” symptom list for the PACT Act, making it easier for eligible veterans to claim their benefits. You can learn more about these symptoms at VA.gov.1With presumptive symptoms, you do not have to show a service connection.
Rather, if you can prove your exposure to toxins in a specified setting and time frame and get a medical diagnosis for your condition, the military will “presume” that there is a service connection—no nexus letter required from a physician.
Presumptive symptoms may include:
- Respiratory conditions (asthma, chronic bronchitis, COPD, pulmonary fibrosis, etc.)
- Cancers (hundreds of different kinds, including lung, prostate, spinal cord, skin, brain, and respiratory cancers)
- Hypertension and heart disease
- Parkinson’s disease
How Do I Prove My Eligibility for PACT Act Compensation?
The military has specified various service locations and accompanying timeframes that qualify veterans for PACT Act benefits. These include (but are not limited to):
- Service in the Vietnam era (1962 to 1980, depending on the country of involvement), Republic of Vietnam, Thailand (at US or Royal Thai bases), Laos, certain provinces in Cambodia, Guam or American Samoa, Johnston Atoll or ships that called at the Atoll).
- Service in the Gulf War (August 2, 1990 onward), Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, United Arab Emirates, and the airspace over these locations.
- Post 9/11 service (September 11, 2001 onward), including Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, Yemen, and the airspace over these countries
If you served in any of these areas during the specified time frames, you might be eligible for certain healthcare benefits and compensation.
To prove eligibility, you should:
- Show you served in a specific location with known toxins.
- Show you served during a qualifying time period.
- Show that you have a medical condition recognized by the VA as being linked to an at-risk service location and time period.
How Do I Apply for PACT Act Compensation?
- Do your research. Check out the PACT Act and see if you meet the requirements for symptoms, service location, and service time frames. For example, if you developed asthma after serving in Afghanistan post-9/11, you may qualify for PACT Act benefits.
- Open your intent to file2 at va.gov or with your local veterans service organization or VA-accredited agent. This opens a 12-month window for you to file and ensures that you get paid dating back to the day you filed.
- Get a current diagnosis. Let’s say you have a diagnosis of asthma that is a few years old. If you haven’t been treated for it recently, the VA will assume it’s getting better. So make sure you get seen for it now to show that the diagnosis still stands and the need for treatment is ongoing.
- Compile lay evidence. Even if you have a presumptive condition that doesn’t require a nexus letter, you’ll want to support your claim with evidence like medical records, service records, personal statements, and buddy letters.
Bonus Tip: Check Out the MUCMI Code
Let’s say you have a “hail Mary” claim based on an issue that you think is connected to in-service toxin exposure but is not recognized as an official presumptive condition. The MUCMI (Medically Unexplained Chronic Multi-Symptom Illness) Code may be your ticket to getting the compensation you deserve.
MUCMIs are diagnosed conditions that are associated with a cluster of symptoms but have no clear cause. Many veterans who were exposed to toxic substances such as Agent Orange, burn pit fumes, etc., have developed MUCMIs.
The PACT Act opens a path for veterans to get a rating for these unexplained illnesses. MUCMIs may include conditions like:
- Fatigue, including chronic fatigue syndrome
- Muscle or joint pain, including conditions like fibromyalgia
- Cognitive issues, such as memory problems or difficulty concentrating
- Headaches
- Gastrointestinal issues, including irritable bowel syndrome
- Sleep disturbances, including sleep apnea
- Mood changes, including anxiety or depression
If you are filing for a VA rating for a MUCMI, make sure to get a current diagnosis and present strong evidence. This could include a personal letter detailing how and when symptoms developed.
For example, let’s say you served as an airplane mechanic and developed depression Write a personal letter explaining the extent of your exposure to jet fuel, when your symptoms developed, and how your symptoms affect your daily life.
You can back your own statement up by having people write “buddy letters” on your behalf. These could be written by veterans who served with you and can vouch for the extent of your jet fuel exposure. They can also be written by family and friends who observed your depression onset and can attest to how your depression has changed your quality of life.
Stay Tuned for More
More and more research is being done on the effects of toxin exposure during military service. Keep an eye out for more PACT Act updates. As researchers understand more about how toxins affect health, there will likely be even more presumptive symptoms added to the list.
