Asthma VA rating
The VA rates asthma under DC 6602 / 6604, and most ratings land in the 0–100% range. What decides yours is the criteria below and what your record actually documents.
This code covers Asthma / COPD.
What the criteria ask for at each level
DC 6602 - 38 CFR §4.97
| Rating | What the record has to show |
|---|---|
| 10% | FEV-1 71–80% predicted, or FEV-1/FVC 71–80%, or intermittent inhalational or oral bronchodilator therapy. |
| 30% | FEV-1 56–70% predicted, or FEV-1/FVC 56–70%, or daily inhalational or oral bronchodilator therapy, or inhalational anti-inflammatory medication. |
| 60% | FEV-1 40–55% predicted, or FEV-1/FVC 40–55%, or at least monthly physician visits for exacerbations, or at least three courses of systemic corticosteroids a year. |
| 100% | FEV-1 under 40% predicted, or FEV-1/FVC under 40%, or more than one attack a week with episodes of respiratory failure, or daily high-dose systemic corticosteroids or immunosuppressives. |
What the C&P exam actually measures
Asthma is rated largely on a number, and the rules about how that number is produced are as consequential as the number itself.
- A pulmonary function test. Without one there is generally nothing for the criteria to read.
- Post-bronchodilator values. §4.96(d)(4) requires the post-bronchodilator study except where the pre-bronchodilator results are normal, or the examiner says why it should not be done.
- How often you use inhalational or oral bronchodilator therapy, and whether any of it is daily.
- Courses of systemic corticosteroids over the past year, and physician visits for exacerbations.
§4.96(d)(5) says the post-bronchodilator results are the ones used - unless they came out poorer than the pre-bronchodilator results, in which case the pre-bronchodilator values are used instead.
Our C&P Prepwalks through what this exam covers, in the schedule's own terms.
Two records, read against the criteria
Two records with almost the same breathing test.
| Outcome | What the record held | How the criteria read it |
|---|---|---|
| Read at 30% | FEV-1 at 74% predicted. A daily inhaled controller, filled every month for four years, with the pharmacy record to show it. | The 74% figure on its own sits in the 10% band. Daily inhalational therapy is a separate, independent route to 30% under DC 6602, and the criteria are joined by "or." |
| Read at 10% | FEV-1 at 74% predicted. A rescue inhaler used a few times a month. No controller medication. | Intermittent inhalational therapy matches the 10% level, and the test value lands in the same band. Nothing in the record reaches a higher route. |
The same lung function, two levels apart. This code is one of several where medication frequency can carry a rating past what the test alone would give. These are general illustrations of how the criteria are written, not a prediction about any particular claim - only the VA decides that, on your own record.
The schedule's own words
Ratings turn on specific terms, and a record that describes the same reality in different language often reads as a lower rating. These are the words this code measures:
- FEV-1 percent predicted
- daily inhalational or oral bronchodilator therapy
- courses of systemic corticosteroids
Evidence that moves this rating
- A pulmonary function test (PFT) - the rating cannot move without it
- Pharmacy refill history showing therapy frequency
What your statement has to cover
Doctors chart symptoms; they rarely chart consequences. That part is yours, and it is usually what separates a documented rating from a reported one.
- List every medication and how often you actually use your inhaler.
- PACT Act: asthma diagnosed AFTER service is PRESUMPTIVE for qualifying burn-pit service.
Our Statement Builderwalks through the questions that produce that kind of statement, in the schedule's own terms.
Where records for this condition fall short
Where asthma records commonly come up short:
- No pulmonary function test in the file
The primary criteria are numeric. A long history of treatment notes has nothing to attach to without the test.
- Only the pre-bronchodilator number recorded
The regulation sets out which value is used and when. A study missing half its results leaves the rater applying a rule to numbers that are not there.
- The medication routes ignored because the test looked fine
Daily inhalational therapy, monthly visits for exacerbations, and three or more courses of systemic corticosteroids a year are each independent routes. Wherever the schedule says "or," a second door is open.
- Steroid courses spread across different clinics
The 60% level counts courses per year. Prescriptions written at urgent care, at an ER and by a primary doctor are three courses that may never appear on one list.
What asthma can lead to 2 documented pathways
A secondary claim runs through a condition the VA already accepts, so the argument about your service is already won. What is left is the medical link - and a nexus opinion has to name the mechanism, not just the pair.
| Can lead to | The mechanism a nexus has to state |
|---|---|
| GERD (acid reflux) | Airway inflammation, chronic coughing, and thoracic pressure changes aggravate reflux. |
| Sleep apnea | Airway inflammation and weight gain from steroid inhalers both raise obstructive sleep apnea risk. Caution: if your respiratory rating is already high, the VA may deny this as pyramiding - respiratory conditions often share one rating. |
A pathway existing in the literature is not the same as your claim being granted - your records and the VA decide that. How secondary claims work covers the argument.
Before you spend money on this claim
VA ratings do not add. Each new rating applies only to the part of you the VA still counts as unimpaired, then rounds to the nearest ten - so from 70%, a new 10% condition leaves you at exactly 70% and changes your payment by nothing.
That does not make the claim worthless; it can still matter for TDIU, for SMC, or later when something else is added. But it is worth knowing before you pay for a nexus letter rather than after. Check what one more condition does at your rating - it takes a minute.
