★ Respiratory
Asthma (Bronchial Asthma) VA Rating
38 CFR § 4.97, Diagnostic Code 6602
Overview
Asthma rating depends on pulmonary function tests (PFTs) and your medication regimen.
PACT Act added asthma diagnosed after burn pit exposure as a presumptive condition.
In Depth
Bronchial asthma is rated under 38 CFR § 4.97, Diagnostic Code 6602 based on pulmonary function testing (PFT) and medication use, whichever produces the higher rating. Tiers: 10% (FEV-1 of 71–80% predicted, OR FEV-1/FVC of 71–80%, OR intermittent inhalational or oral bronchodilator therapy), 30% (FEV-1 of 56–70% predicted, OR FEV-1/FVC of 56–70%, OR daily inhalational or oral bronchodilator therapy, OR inhalational anti-inflammatory medication), 60% (FEV-1 of 40–55% predicted, OR FEV-1/FVC of 40–55%, OR at least monthly visits to a physician for required care of exacerbations, OR intermittent — at least three per year — courses of systemic (oral or parenteral) corticosteroids), 100% (FEV-1 less than 40% predicted, OR FEV-1/FVC less than 40%, OR more than one attack per week with episodes of respiratory failure, OR requires daily use of systemic high-dose corticosteroids or immuno-suppressive medications).
The 'whichever is higher' rule matters — a veteran with normal PFTs but on daily inhaled corticosteroids generally qualifies for at least 30%. Medication tier alone can drive the rating without PFT changes.
Bronchial asthma is presumptive under the PACT Act for veterans who served in covered post-9/11 locations (38 USC § 1119). The presumption removes the nexus burden but still requires a current diagnosis.
PFTs are commonly performed post-bronchodilator. When the C&P examiner records only pre-bronchodilator values, the veteran or representative should request the post-bronchodilator FEV-1 used for VA rating purposes.
How to Establish Service Connection
- PACT Act presumptive for qualifying airborne hazards.
- Direct: in-service onset documented in STRs.
Rating Criteria
Paraphrased from 38 CFR § 4.97, Diagnostic Code 6602
| Rating | Criteria |
|---|---|
| 10% | FEV-1 of 71–80% predicted; or FEV-1/FVC of 71–80%; or intermittent inhalational or oral bronchodilator therapy. |
| 30% | FEV-1 of 56–70%; or FEV-1/FVC of 56–70%; or daily inhalational or oral bronchodilator therapy or anti-inflammatory medication. |
| 60% | FEV-1 of 40–55%; or FEV-1/FVC of 40–55%; or at least monthly visits to a physician for required care of exacerbations; or intermittent (≥3/year) courses of systemic corticosteroids. |
| 100% | FEV-1 less than 40%; or FEV-1/FVC less than 40%; or more than one attack per week with episodes of respiratory failure; or requires daily use of systemic high-dose corticosteroids or immunosuppressives. |

Evidence Checklist
- Recent pulmonary function test (PFT) showing FEV-1 and FEV-1/FVC values.
- Prescription records showing inhaler frequency and any oral steroid courses.
- PACT Act exposure documentation.
Evidence Templates
Common formats of evidence the VA looks for in this type of claim. These describe what the documents typically include — they are not legal forms or medical opinions, and Oakridge Claims does not draft them.
Pulmonary Function Test (Post-Bronchodilator)
Complete PFT report including pre- and post-bronchodilator FEV-1, FVC, and FEV-1/FVC ratio.
Complete Medication List
Treating-physician medication list showing inhaler type, dosing frequency, and any oral steroid courses by date.
Exacerbation Treatment Records
Urgent care, ER, or office-visit notes documenting asthma exacerbations and treatment.
Evidence VA Commonly Cites in These Claims
Descriptive summary of evidence types frequently referenced in rating decisions for this condition. Not a checklist of actions to take — every claim is decided on its own facts.
- ★Make sure the C&P examiner records post-bronchodilator FEV-1 and FEV-1/FVC, not just pre-bronchodilator values.
- ★Maintain a complete medication list with dates and dosages — daily inhaled corticosteroids alone commonly support 30%; three or more oral steroid courses per year commonly support 60%.
- ★Track exacerbations requiring physician visits — monthly visits for exacerbation management commonly support 60%.
- ★When PACT Act presumption applies, file with the PACT Act intent-to-file specifically noted to ensure presumptive evaluation.
Illustrative Scenarios
These are hypothetical educational examples — not actual case results, predictions, or guarantees of outcomes.
Scenario — Medication-Driven 30%
A veteran has normal post-bronchodilator FEV-1 but uses a daily inhaled corticosteroid (fluticasone) prescribed by their pulmonologist. Under DC 6602, daily inhalational anti-inflammatory medication generally supports a 30% rating regardless of normal PFTs — though the actual decision is the VA's.
Common pitfalls VA sees
- Accepting a low rating based on pre-bronchodilator PFTs when post-bronchodilator values would apply.
- Failing to document daily inhaled corticosteroid use, which commonly drives the 30% tier independent of PFT results.
- Missing the PACT Act presumptive pathway for post-9/11 deployment-era veterans.
Frequently Asked Questions
Have a Asthma (Bronchial Asthma) claim or denial?
Four fields. A VA-accredited claims agent reviews it and responds within 3–5 business days. Contingent fees apply only to awarded past-due benefits on appeals — never on initial claims.
Requesting a consultation does not create representation and is not a guarantee of any outcome. Representation begins only after a written fee agreement and VA Form 21-22a are signed.
Educational content only — not legal advice and not medical advice. Rating criteria on this page are summarized in plain English from 38 CFR Part 4; consult VA.gov or the current Code of Federal Regulations for official criteria. This page provides general education about how the VA rates this condition; it is not individualized advice, does not establish a representation relationship, and should not be used to self-diagnose, self-treat, or decide a course of action without speaking to a qualified clinician and a VA-accredited representative. Outcomes depend on each veteran's individual facts, evidence, and the adjudicator's judgment; no specific rating, effective date, or other result is guaranteed.
