The VA rates chronic bronchitis under Diagnostic Code 6600 at 10%, 30%, 60%, or 100%, and the rating is decided almost entirely by pulmonary function test numbers. A veteran with an FEV-1 of 71% to 80% of predicted value gets 10%. An FEV-1 below 40% predicted, or a need for outpatient oxygen therapy, gets 100%. In 2026, those two ends of the scale pay $180.42 and $3,938.58 per month for a veteran with no dependents.
Two things about this diagnostic code catch veterans off guard. Acute bronchitis, the kind that clears up in a few weeks, is not ratable at all. And if you already have a service-connected COPD or asthma rating, you generally cannot stack a separate bronchitis rating on top of it. Both are explained below, along with the PACT Act burn pit pathway that lets many post-9/11 and Gulf War veterans skip the hardest part of the claim.
Chronic Bronchitis Rating Criteria (Diagnostic Code 6600)
The VA does not rate chronic bronchitis on how often you cough or how much sputum you produce. It rates the measurable loss of lung function, using three numbers from a pulmonary function test (PFT):
- FEV-1: Forced Expiratory Volume in one second, or how much air you can force out of your lungs in the first second of a hard exhale, expressed as a percentage of what a healthy person your age, height, and sex should manage.
- FEV-1/FVC: the ratio of that one-second volume to your total forced vital capacity. A low ratio points to airway obstruction.
- DLCO (SB): Diffusion Capacity of the Lung for Carbon Monoxide by the Single Breath method, which measures how well oxygen crosses from your lungs into your blood.
You do not need to meet all three. Meeting any single criterion at a given tier qualifies you for that tier. Here are the exact thresholds from 38 CFR 4.97.
| Rating | FEV-1 (% predicted) | FEV-1/FVC | DLCO (SB) (% predicted) | Other qualifying criteria |
|---|
| 10% | 71% to 80% | 71% to 80% | 66% to 80% | None |
| 30% | 56% to 70% | 56% to 70% | 56% to 65% | None |
| 60% | 40% to 55% | 40% to 55% | 40% to 55% | Maximum oxygen consumption of 15 to 20 ml/kg/min with cardiorespiratory limit |
| 100% | Less than 40% | Less than 40% | Less than 40% | Max exercise capacity under 15 ml/kg/min with cardiac or respiratory limitation; or cor pulmonale (right heart failure); or right ventricular hypertrophy; or pulmonary hypertension shown by echo or cardiac catheterization; or episodes of acute respiratory failure; or requires outpatient oxygen therapy |
The 100% tier is worth reading twice. Seven of its nine qualifying criteria have nothing to do with your FEV-1 number. If you require outpatient oxygen therapy, or you have documented cor pulmonale, right ventricular hypertrophy, or pulmonary hypertension confirmed by echocardiogram or cardiac catheterization, you meet the 100% criteria regardless of how your PFT reads that day. Veterans get underrated here constantly because the C&P examiner recorded the PFT and nobody flagged the oxygen prescription already sitting in the medical record.
Note also that the 30% tier is the only place where DC 6600 and the COPD code differ in how DLCO is written out. Under DC 6600, a DLCO of 56% to 65% predicted supports 30% on its own.
2026 VA Compensation for a Bronchitis Rating
VA disability rates rose 2.8% effective December 1, 2025, matching the Social Security cost of living adjustment. These are the current VA rates for the four tiers available under DC 6600.
| Rating | Veteran alone | Veteran with spouse |
|---|
| 10% | $180.42 | $180.42 |
| 30% | $552.47 | $617.47 |
| 60% | $1,435.02 | $1,566.02 |
| 100% | $3,938.58 | $4,158.17 |
Additional dependent compensation starts at 30%. A veteran rated 10% or 20% receives the same monthly amount regardless of household size. Above 30%, spouse, children, and dependent parents each add to the monthly payment, and a spouse requiring aid and attendance adds more. Check the official rate tables for your exact dependent combination.
Chronic Bronchitis vs Acute Bronchitis for VA Purposes
This is where a lot of bronchitis claims die, and it is worth being blunt about it. Diagnostic Code 6600 is titled "Bronchitis, chronic." Acute bronchitis, the post-viral cough that resolves in two to six weeks, is not a ratable disability. VA compensation exists for current, ongoing disability, so an illness that has fully resolved leaves nothing to evaluate.
The clinical definition matters for your evidence. Chronic bronchitis is generally diagnosed when a productive cough persists for at least three months a year in two consecutive years, with other causes ruled out. If your service treatment records show three separate winters of "acute bronchitis" treated with antibiotics and nothing since, the VA will likely deny the claim as an acute and transitory condition, not a chronic disability.
What turns that around:
- A current diagnosis of chronic bronchitis in your medical records, using that word
- Documentation of persistent symptoms across time, not isolated episodes
- Recent PFT results showing measurable obstruction
- Treatment history showing ongoing management, such as maintenance inhalers or repeated pulmonology visits
If your PFT results are normal and you have no measurable impairment, the VA can grant service connection and still assign a 0% rating. A 0% rating pays nothing, but it establishes service connection, which protects your ability to file for an increase later if the condition worsens.
The PACT Act Pathway: Chronic Bronchitis Is Presumptive
This is the most valuable thing on this page for any veteran who deployed to Southwest Asia or the post-9/11 theaters. Chronic bronchitis is on the PACT Act list of presumptive conditions for burn pits and other airborne hazards. If you have a current chronic bronchitis diagnosis and you served in a covered location during a covered period, the VA presumes the condition is related to your service. You do not need a nexus letter. You do not need to prove which burn pit, which base, or which year.
Covered service locations and dates:
| Era | Locations | Dates |
|---|
| Gulf War era | Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, United Arab Emirates, and the airspace above these locations | On or after August 2, 1990 |
| Post-9/11 era | Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, Yemen, and the airspace above these locations | On or after September 11, 2001 |
Chronic bronchitis is one of a dozen respiratory conditions on the burn pit presumptive list, alongside asthma diagnosed after service, COPD, emphysema, constrictive bronchiolitis, granulomatous disease, interstitial lung disease, pleuritis, pulmonary fibrosis, sarcoidosis, chronic rhinitis, and chronic sinusitis.
One distinction that trips people up: there is a separate, older particulate matter presumption at 38 CFR 3.320, created in 2021, that covers only asthma, rhinitis, and sinusitis and requires the condition to manifest within 10 years of separation. Chronic bronchitis is not on that shorter list. It reaches presumptive status through the PACT Act's burn pit provisions instead, which is the broader pathway. If a decision letter cites 3.320 to deny your bronchitis claim, the PACT Act pathway is the one to raise on appeal.
Bronchitis and COPD Together: The Anti-Pyramiding Rule
Chronic bronchitis is one of the two clinical components of COPD, so many veterans carry both diagnoses. You will not receive two ratings for it.
38 CFR 4.14 prohibits pyramiding, defined as evaluating the same disability or the same manifestation under different diagnoses. The respiratory schedule goes further and states the rule explicitly. Under 38 CFR 4.96(a), ratings under diagnostic codes 6600 through 6817 and 6822 through 6847 will not be combined with each other. The rater assigns a single evaluation under the code that reflects the predominant disability, and may elevate that evaluation one level if the overall severity warrants it.
In practice, that means a veteran with chronic bronchitis and COPD gets one respiratory rating, not a 30% and a 30% combined. What you can control is which code is used and whether all your evidence made it into the file. Since DC 6600, DC 6603 (emphysema), and DC 6604 (COPD) share nearly identical PFT thresholds, the code label usually matters less than making sure the rater saw your worst supportable numbers and any of the alternative 100% criteria.
Conditions in other body systems are treated differently. If your chronic bronchitis contributed to a separate heart condition, that condition is rated on its own and combined using the VA's combined ratings table.
PFT Rules That Change Your Rating
38 CFR 4.96(d) sets several technical rules for how the VA applies PFT results to DC 6600. They are worth knowing because each one has cost veterans a tier.
- Post-bronchodilator results govern. Testing must include post-bronchodilator studies unless pre-bronchodilator results are normal or the examiner states why the test should not be done. The VA uses the post-bronchodilator numbers unless the pre-bronchodilator results were actually poorer, in which case it uses those.
- A missing DLCO is not automatically fatal. If DLCO is not of record, the VA evaluates based on the other criteria, provided the examiner states why the test would not be useful in your case. But if DLCO would have supported a higher tier than FEV-1, its absence quietly costs you. Ask for it.
- When FEV-1 and FEV-1/FVC disagree, the examiner should state which result more accurately reflects the level of disability, and the VA rates accordingly.
- A PFT is not always required. If maximum exercise capacity testing shows 20 ml/kg/min or less, or you have documented pulmonary hypertension, cor pulmonale, or right ventricular hypertrophy, or episodes of acute respiratory failure, or you require outpatient oxygen therapy, the rating can be assigned without new PFT results.
How to File a Chronic Bronchitis Claim
- Confirm the diagnosis says chronic. Pull your medical records and check the exact wording. If your provider has only ever coded acute episodes, ask for a pulmonology referral and an explicit chronic bronchitis assessment.
- Get a current PFT with post-bronchodilator and DLCO values. Results older than about a year are usually treated as stale. Ask your provider to run DLCO, not just spirometry.
- Document your service location and dates. For a PACT Act claim, your DD-214 and deployment records showing a covered location and period do most of the work. Also complete the VA's toxic exposure screening at your VA facility.
- File VA Form 21-526EZ. Submit online at VA.gov, by mail, or with a Veterans Service Organization such as the DAV, VFW, or American Legion. VSO help is free, and accredited representatives handle these claims routinely.
- Consider filing an intent to file first. Submitting an intent to file locks in your effective date for up to a year while you gather evidence, which can mean months of retroactive back pay.
- Attend the C&P exam and be accurate. The examiner will likely order a PFT. Do not skip your maintenance inhaler if you normally take it, but do describe your symptoms on a typical bad day, not just how you feel in the exam room.
Why Bronchitis Claims Get Denied or Underrated
- The record shows only acute episodes. Isolated infections during service, with no chronic diagnosis now, get denied as acute and transitory.
- No recent PFT. Without current numbers, the rater has nothing to apply the criteria to and often assigns 0%.
- DLCO never ordered. FEV-1 alone can undershoot the tier that DLCO would have supported.
- Oxygen therapy or cor pulmonale missed. These are standalone 100% criteria that get overlooked when the rater focuses on PFT numbers.
- Rated as a lesser respiratory code without elevation. When multiple respiratory conditions exist, the rater must pick the predominant disability and consider elevating one level. If that analysis is missing from your decision letter, it is an appealable issue.
If the decision is wrong, you have one year from the decision date to file a Supplemental Claim with new evidence, a Higher-Level Review, or a Board appeal.
Frequently Asked Questions
What is the VA disability rating for chronic bronchitis?
Chronic bronchitis is rated under Diagnostic Code 6600 at 10%, 30%, 60%, or 100%. The tier is set by pulmonary function test results: FEV-1 of 71% to 80% predicted for 10%, 56% to 70% for 30%, 40% to 55% for 60%, and under 40% for 100%. FEV-1/FVC ratio and DLCO results can independently support the same tiers.
Can you get VA disability for acute bronchitis?
No. Acute bronchitis resolves and leaves no ongoing disability to evaluate, so there is nothing for the VA to rate. Diagnostic Code 6600 applies to chronic bronchitis, generally meaning a productive cough for at least three months a year in two consecutive years with measurable impairment.
Is chronic bronchitis a PACT Act presumptive condition?
Yes. Chronic bronchitis is on the burn pit and airborne hazards presumptive list. Veterans who served in Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, or the UAE on or after August 2, 1990, or in Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, or Yemen on or after September 11, 2001, do not have to prove their chronic bronchitis was caused by service.
Can I get separate VA ratings for bronchitis and COPD?
No. Under 38 CFR 4.96(a), respiratory ratings in the 6600 to 6817 and 6822 to 6847 range are not combined with each other. The VA assigns a single rating under the code reflecting the predominant disability, and may elevate it one level if overall severity justifies it. Rating both separately would be pyramiding under 38 CFR 4.14.
How do I get 100% for chronic bronchitis?
An FEV-1, FEV-1/FVC, or DLCO under 40% predicted qualifies. So does maximum exercise capacity under 15 ml/kg/min with a cardiac or respiratory limit, cor pulmonale, right ventricular hypertrophy, pulmonary hypertension confirmed by echo or cardiac catheterization, episodes of acute respiratory failure, or a requirement for outpatient oxygen therapy. Any one of those is enough.
Does the VA use pre or post-bronchodilator PFT results?
Post-bronchodilator results are used, unless the pre-bronchodilator results were poorer, in which case the pre-bronchodilator numbers apply. Testing must include post-bronchodilator studies unless pre-bronchodilator results are normal or the examiner documents a reason not to perform them.
What if my bronchitis claim was denied before the PACT Act?
You can file a Supplemental Claim. The VA has reviewed and readjudicated many previously denied respiratory claims under the PACT Act, and in some cases the effective date can reach back to the original claim. Raise the PACT Act presumptive pathway explicitly rather than relying on the older particulate matter rule at 38 CFR 3.320, which covers only asthma, rhinitis, and sinusitis.
Will the VA reduce my bronchitis rating later?
It can schedule future exams if your condition is not considered static, and a new PFT showing improvement can support a reduction. Ratings in place for 20 years or more are generally protected from reduction below that level. Keeping current PFT results on file protects you in both directions.
