Pulmonary Fibrosis
Permanent scarring of the lungs from inhaled hazards — rated up to 100%.
Pulmonary fibrosis is scarring of the lung tissue itself. Unlike a flare of asthma or bronchitis, the scarring does not heal — it stiffens the lungs so they cannot expand or transfer oxygen normally, and it tends to worsen over time. For veterans who inhaled burn-pit smoke and fine particulate, it is a recognized long-term consequence under the PACT Act.
Because it is permanent and measurable, a well-documented fibrosis claim is strong. The VA rates it on objective breathing tests. Here is what it is, why the exposure link matters, and what each rating level requires.
Understanding Pulmonary Fibrosis
Pulmonary fibrosis is the thickening and scarring of the tissue between and around the air sacs of the lungs. It causes a dry cough, progressive shortness of breath and fatigue, and it is measured by how much it restricts lung volume and impairs the transfer of oxygen into the blood.
The exposure link the VA now accepts for you
Repeated inhalation of fine particulate, dioxins and chemical irritants from burn pits and desert dust can drive the chronic inflammation that leads to fibrosis. Interstitial lung disease and fibrosis fall under the PACT Act’s airborne-hazard framework for veterans with qualifying exposure.
Because this is a presumptive condition, you do not have to prove the science of how your service caused it. If you have a qualifying diagnosis and served in a covered location during a covered period, the VA presumes the connection — your job is to file, attend the exam, and make sure the rating reflects how badly it truly affects you.
Why this hits women differently
Women veterans breathed the same air, and progressive breathlessness in women is frequently written off before a CT scan or breathing test reveals the scarring. Objective testing is what proves the disease and secures the rating.
What the VA Pays for Pulmonary Fibrosis
Pulmonary Fibrosis is rated under 38 CFR 4.97, Diagnostic Code 6825 (diffuse interstitial fibrosis). Here is exactly what each level requires, in plain English — not a table you have to decode.
FVC of 75–80% of predicted, or a DLCO (gas transfer) of 66–80% of predicted.
FVC of 65–74% of predicted, or a DLCO of 56–65% of predicted.
FVC of 50–64% of predicted, or a DLCO of 40–55%, or maximum exercise capacity of 15–20 ml/kg/min oxygen consumption.
FVC less than 50% of predicted, or a DLCO less than 40%, or maximum exercise capacity below 15 ml/kg/min, or cor pulmonale (right heart failure), or the need for outpatient oxygen therapy.

One rating is rarely the whole picture
This condition does not stand alone. The VA combines it with every other service-connected condition you carry using its combined-ratings math — so a presumptive claim can push your overall rating higher than this one number suggests. And if your toxic-exposure conditions together make it impossible to hold steady, gainful work, you may qualify for TDIU (Total Disability based on Individual Unemployability) and be paid at the 100% rate even if no single condition reaches 100%. This is one of the most overlooked ways women veterans are underpaid.
Getting this rated at its true severity
Keep your CT imaging and full pulmonary function test results together, and note any prescribed oxygen. Describe your breathing on your worst days at the exam. An accredited representative can confirm the presumption and that the rating reflects the permanent loss.
Do you qualify for Pulmonary Fibrosis?
Under the PACT Act, a presumptive claim comes together when two things are true at once: you have a diagnosis of pulmonary fibrosis, and your service falls inside one of the covered toxic-exposure windows below. When both are met, the VA presumes your condition is service-connected — you do not have to prove how the exposure caused it.
Post-9/11 service
Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan or Yemen — or the airspace above them — on or after September 11, 2001.
Gulf War-era service
Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia or the United Arab Emirates — or the airspace above them — on or after August 2, 1990.
Agent Orange & other exposures
Vietnam, Thailand, the Korean DMZ, Camp Lejeune and other recognized sites each carry their own presumptive rules and dates on top of the burn-pit windows.
Not sure whether your dates and locations line up? That is one of the most common reasons a valid claim gets denied — and one of the easiest to fix with the right records. An accredited representative can confirm your covered service before you file.
Filing a claim for Pulmonary Fibrosis, step by step
You can file a PACT Act claim on your own — but knowing the order of operations keeps it from stalling. Here is what the process looks like from start to decision.
Confirm the diagnosis
Make sure the condition is documented in your medical records — from the VA or a private doctor. A clear, current diagnosis is the first half of a presumptive claim.
Establish your covered service
Pull your DD-214, deployment orders and duty history to show you served in a covered location during a covered period. This is the second half — and once both are met, the VA presumes the link.
File the claim
File for disability compensation and specify the condition and your toxic exposure. You can file it yourself, but an accredited representative can file it correctly the first time and make sure nothing is left off.
Attend the C&P exam
The VA will schedule a Compensation & Pension exam. Describe your symptoms on your worst days, not your best — the rating is set from what the examiner records.
You do not have to do this alone
