Chronic Cough After Deployment: How to Document Symptoms for a Clear Medical Record (2026)
Many Veterans return from deployment with a “hacking” cough. You might have heard it called the “Iraq itch” or “Kabul cough.” While many assume it is just a side effect of dry air or dust, a cough that lasts more than eight weeks is medically considered a chronic cough.
In the toxic environments of modern deployment, this symptom is rarely “just a cough.” It is often a signal of underlying damage to the lungs or airways caused by burn pits, jet fuel, or sandstorms. According to 2026 data from the Airborne Hazards and Open Burn Pit Registry, chronic cough remains the most common respiratory complaint among Post-9/11 Veterans.
Why Chronic Cough is a “Red Flag”
A cough is a symptom, not a final diagnosis. To the VA, a cough is a “red flag” that points to a specific condition. Under the PACT Act, several conditions that cause a chronic cough are now “presumptive.” This means if you served in covered locations, the VA assumes the condition is service-connected.
Common presumptive conditions include:
- Chronic Bronchitis: Constant swelling of the large breathing tubes.
- Asthma: Narrowing of the airways, often triggered by dust or smoke.
- Chronic Rhinitis/Sinusitis: Post-nasal drip that irritates the throat and triggers coughing fits.
- Constrictive Bronchiolitis: A serious condition affecting the smallest branches of the lungs.

The “Invisible” Condition: Constrictive Bronchiolitis
One of the biggest challenges for Veterans in 2026 is Constrictive Bronchiolitis (also known as “Popcorn Lung”). Many Veterans report a violent cough and shortness of breath, yet their standard Pulmonary Function Tests (PFTs) come back “normal.”
This happens because the damage is located deep in the smallest branches of the lungs (the bronchioles). Standard “breath-into-a-tube” tests are great at measuring how much air you can hold, but they are bad at seeing damage in these tiny, deep areas.
Evidence that may help document this condition:
- High-Resolution CT (HRCT) Scan: This is more detailed than a regular X-ray. It can show “air trapping,” where old air gets stuck in your lungs because the tiny tubes are scarred shut.
- Lung Biopsy: This is the “gold standard” for a diagnosis. It involves taking a tiny piece of lung tissue to look for scarring under a microscope.
- Exercise Challenge: Documenting that your cough and breathing become significantly worse during physical activity.
How the VA Rates Respiratory Conditions
The VA generally evaluates respiratory conditions under Diagnostic Codes 6600 through 6604. The rating percentage is typically based on your lung function test results, specifically your FEV-1 (the amount of air you can blow out in one second).
| Potential Rating | Typical Medical Evidence Thresholds (2026) |
| 100% | FEV-1 less than 40% of predicted value, or a requirement for outpatient oxygen. |
| 60% | FEV-1 between 40% and 55%, or at least three courses of systemic steroids per year. |
| 30% | FEV-1 between 56% and 70%, or a requirement for daily inhaler use. |
| 10% | FEV-1 between 71% and 80%, or intermittent use of an inhaler. |
Building a 4-Part Medical Evidence Record
To create a thorough clinical history, your medical records should ideally address these four areas:
- Symptom History: Record when the cough started. Does it wake you up at night? Do you cough until you gag or vomit? This is called “subjective evidence.”
- Clinical Provider Notes: Ensure your doctor notes the frequency of the cough. Instead of “patient has a cold,” the record should reflect “patient reports daily cough since 2014 deployment.”
- Objective Testing: This includes PFTs, X-rays, and CT scans. Even if a test comes back “normal,” it is a piece of evidence that helps doctors rule out other causes.
- Environmental Triggers: Document what makes the cough worse. Does cold air, humidity, or exercise trigger a “coughing fit”? This helps show the cough is a chronic problem and not just a temporary illness.

The “Domino Effect” (Secondary Conditions)
A chronic cough doesn’t just stay in your chest; it impacts your entire body. Documentation should include how your cough leads to:
- Sleep Disruption: Nighttime coughing can lead to chronic fatigue and may worsen sleep apnea.
- GERD (Acid Reflux): Constant coughing can weaken the valve between your stomach and throat. This creates a cycle where the reflux causes more coughing.
- Chest and Abdominal Strain: Physical pain caused by the muscle strain of violent, long-term coughing fits.
