The VA rates bronchial asthma under Diagnostic Code 6602 at one of four levels: 10%, 30%, 60%, or 100%. Your rating depends on pulmonary function test (PFT) results and how much medication you need to control your symptoms. A veteran with mild, occasional asthma who uses an inhaler as needed typically lands at 10%, while a veteran who needs daily high-dose steroids or has frequent respiratory failure can qualify for a 100% rating. In 2026, a 100% rating pays $3,938.58 per month for a veteran with no dependents.
Asthma is one of the most commonly filed VA claims, and thanks to the PACT Act, many veterans who developed asthma after burn pit or airborne hazard exposure no longer have to prove their asthma was caused by their service. This guide breaks down the exact rating criteria, current 2026 pay rates, and how to file a strong claim.
How the VA Rates Asthma (Diagnostic Code 6602)
The VA uses your pulmonary function test results, specifically your FEV-1 (forced expiratory volume in one second) and FEV-1/FVC ratio, along with your medication requirements, to assign a rating. You only need to meet one of the criteria at a given level to qualify for that rating, not all of them.
| Rating | FEV-1 (% predicted) | FEV-1/FVC | Medication or Treatment Requirement |
|---|
| 10% | 71% to 80% | 71% to 80% | Intermittent inhalational or oral bronchodilator therapy |
| 30% | 56% to 70% | 56% to 70% | Daily inhalational or oral bronchodilator therapy, or inhalational anti-inflammatory medication |
| 60% | 40% to 55% | 40% to 55% | Monthly visits to a physician for exacerbations, or at least 3 courses per year of systemic corticosteroids |
| 100% | Less than 40% | Less than 40% | More than 1 attack per week with episodes of respiratory failure, or daily use of high-dose systemic corticosteroids or immunosuppressive medications |
A few things to know about how this works in practice:
- The VA uses the result that gives you the higher rating if your FEV-1 and FEV-1/FVC scores fall into different brackets.
- Your PFT results should be measured after using your bronchodilator (post-bronchodilator), unless post-bronchodilator studies are not indicated.
- Asthma and other respiratory conditions like COPD or sleep apnea are usually rated under a single respiratory rating rather than combined separately, because VA regulations generally don't allow separate ratings for conditions under the same body system that overlap in symptoms. If you have both asthma and another respiratory condition, you typically get whichever single rating is higher, not both added together.
2026 VA Disability Pay Rates by Rating
VA disability compensation increased by 2.8% for 2026, effective December 1, 2025. Here are the current monthly payments for a veteran with no dependents.
| VA Rating | Monthly Payment (Veteran Alone) |
|---|
| 10% | $180.42 |
| 30% | $552.47 |
| 60% | $1,435.02 |
| 100% | $3,938.58 |
If you have a spouse, children, or dependent parents, your payment increases at the 30% rating and above. A 100% rated veteran with a spouse receives approximately $4,158.17 per month. Veterans rated below 30% do not receive additional compensation for dependents, even if you're married with kids.

Does Asthma Qualify as a PACT Act Presumptive Condition?
Yes, in many cases. Under the PACT Act, asthma diagnosed after military service is a presumptive condition if you served in a location and time period associated with burn pit or airborne hazard exposure, including Iraq, Afghanistan, and other Southwest Asia locations after August 2, 1990, and certain other qualifying locations going back to 1955 for specific exposures. Presumptive service connection means you don't have to prove your asthma was caused by your service. You only need:
- A current diagnosis of asthma
- Proof of qualifying military service in an eligible location and time frame
If your asthma was diagnosed while you were still on active duty, it's typically rated as a direct service-connected condition rather than a PACT Act presumptive condition, but the rating criteria under Diagnostic Code 6602 are the same either way.
If you don't qualify for presumptive service connection, you can still file a direct service connection claim. You'll need:
- A current asthma diagnosis
- An in-service event, exposure, or injury (such as documented exposure to chemicals, smoke, dust, or a respiratory illness during service)
- A medical nexus letter connecting your current asthma to that in-service event
Secondary Conditions Connected to Asthma
Asthma often triggers or worsens other health conditions. If you can show that a secondary condition developed because of your service-connected asthma, you may be able to file for additional compensation. Conditions commonly connected as secondary to asthma include:
- GERD (acid reflux)
- Obstructive sleep apnea
- Chronic bronchitis
- Hypertension
- Vocal cord dysfunction
- Anxiety or depression related to chronic illness
Each secondary condition gets its own rating, which is then combined with your asthma rating using the VA's combined ratings table, not simple addition.
How to File a VA Claim for Asthma
- Get a current diagnosis. You need a doctor's diagnosis of asthma on file, ideally with recent pulmonary function test results.
- Gather evidence of service connection. This includes service treatment records, deployment records showing burn pit or hazard exposure, and buddy statements if relevant.
- File your claim online at VA.gov. Use the disability compensation application and select asthma or the appropriate respiratory condition.
- Attend your Compensation and Pension (C&P) exam. The VA will schedule a PFT and a medical exam to assess your current severity.
- Wait for your rating decision. The VA will issue a decision letter with your assigned percentage and effective date.
- Appeal if the rating seems too low. You have options including a Higher-Level Review, Supplemental Claim with new evidence, or an appeal to the Board of Veterans' Appeals.
Keep a copy of every PFT result and medication record. If your asthma worsens over time, you can file a claim for an increased rating using updated medical evidence.
Can Asthma Qualify You for TDIU?
Total Disability based on Individual Unemployability (TDIU) allows veterans to receive compensation at the 100% rate even if their combined schedular rating is lower than 100%, as long as their service-connected conditions prevent them from holding substantially gainful employment. If your asthma alone or combined with secondary conditions like sleep apnea, GERD, or anxiety keeps you from working full-time, you may qualify for TDIU with a lower combined rating, typically 60% for a single condition or 70% combined across multiple conditions. To apply, you'll need to file VA Form 21-8940 along with medical and vocational evidence showing how your respiratory symptoms limit your ability to work.
Common Reasons Asthma Claims Get Denied or Underrated
Several issues tend to trip up veterans filing asthma claims:
- Missing pulmonary function test results. Without a current PFT on file, the VA has no objective data to assign a rating above the minimum.
- Pre-bronchodilator vs. post-bronchodilator confusion. The rating is typically based on post-bronchodilator results, so make sure your test includes both readings.
- Weak nexus evidence for direct service connection. If you don't qualify under PACT Act presumptive rules, you need a doctor's statement clearly linking your asthma to a specific in-service event or exposure.
- Not documenting medication frequency. The VA looks closely at whether bronchodilator or corticosteroid use is intermittent, daily, or high-dose, so keep pharmacy records and prescription history.
- Treating asthma and other respiratory conditions as separate ratings. As noted above, the VA usually assigns one combined respiratory rating rather than stacking multiple percentages, so don't expect asthma and COPD to add up separately in most cases.
If your claim comes back lower than expected, request your C&P exam report and compare the examiner's findings against the Diagnostic Code 6602 criteria. Discrepancies between your medical records and the exam findings are one of the most common grounds for a successful appeal.
Frequently Asked Questions
What is the VA disability rating for asthma?
The VA rates asthma at 10%, 30%, 60%, or 100% under Diagnostic Code 6602, based on pulmonary function test results and how much medication you require to manage symptoms.
How much does the VA pay for a 30% asthma rating in 2026?
A veteran with a 30% VA disability rating and no dependents receives $552.47 per month in 2026. The amount increases if you have a spouse, children, or dependent parents.
Can I get 100% VA disability for asthma?
Yes, if your FEV-1 or FEV-1/FVC is below 40% predicted, or you have more than one asthma attack per week with respiratory failure episodes, or you require daily high-dose systemic corticosteroids or immunosuppressive medications.
Is asthma a PACT Act presumptive condition?
Asthma diagnosed after service can be a PACT Act presumptive condition for veterans who served in locations with documented burn pit or airborne hazard exposure, including Iraq, Afghanistan, and other qualifying areas. This removes the requirement to prove your asthma was caused by your service.
Can asthma and sleep apnea be rated separately by the VA?
Usually not. The VA generally rates overlapping respiratory conditions under a single rating rather than combining them, since they fall under the same body system and often share symptoms. You typically receive whichever single rating is highest.
How do I increase my VA asthma rating?
File a claim for an increased rating with updated pulmonary function test results and medical records showing your condition has worsened, such as new prescriptions, more frequent physician visits, or worsening PFT scores.
What if my asthma claim gets denied?
You can request a Higher-Level Review, file a Supplemental Claim with new and relevant evidence, or appeal directly to the Board of Veterans' Appeals. A denial is not always final, and many veterans successfully win on appeal with stronger medical documentation.
