Interstitial Lung Disease (ILD) VA Disability Rating

Diagnostic code 6825
By the editorial deskUpdated Jun 13, 2026Sources verified Jun 13, 2026
Presumptive under: PACT Act
Quick summary
Interstitial lung disease is rated under the restrictive lung formula (diagnostic codes 6825 to 6833) from 10 to 100 percent based on FVC, DLCO, exercise capacity, and complications such as pulmonary hypertension or oxygen use. ILD is on the PACT Act presumptive list for veterans with qualifying service.
Key requirements
  • Service connection requires a current diagnosis, an in-service event or exposure, and a medical link (nexus) between the two.
  • VA assigns ratings of 10% to 100% under diagnostic code 6825, using the criteria in the rating table below.
  • The percentage assigned turns on FVC, DLCO, and exercise capacity.
  • Measured at the C&P exam: Pulmonary function test.
  • Presumptive service connection may apply under the PACT Act for veterans with qualifying service.
VA also uses diagnostic code 6825 for Pulmonary Fibrosis (Interstitial Lung Disease). Those are distinct conditions with their own pages. This page covers Interstitial Lung Disease (ILD) specifically.
This page explains common evidence VA may consider when rating this condition. It is not medical advice and does not diagnose any condition. Talk with a licensed medical professional about diagnosis and treatment, and with a VA accredited representative (38 CFR 14.629) about a specific claim.

Illustrative scenarios showing how the criteria above are applied. These are educational examples, not a prediction of any individual veteran's rating.

Mild reduction on breathing tests

Illustrates 10%

Situation. Interstitial lung disease shows FVC at about 78 percent of predicted, or DLCO around 70 percent.

How the criteria apply. FVC of 75 to 80 percent predicted, or DLCO of 66 to 80 percent predicted, rates 10 percent under DC 6825.

Moderate reduction on breathing tests

Illustrates 30%

Situation. PFTs show FVC at about 70 percent of predicted, or DLCO around 60 percent.

How the criteria apply. FVC of 65 to 74 percent predicted, or DLCO of 56 to 65 percent predicted, rates 30 percent under DC 6825.

How this is usually measured. Most lung conditions are rated from a pulmonary function test, also called a PFT or spirometry. The test records values such as FEV-1, FVC, the FEV-1 to FVC ratio, and DLCO. Under 38 CFR 4.96, the rating is generally read from the post bronchodilator results unless the report explains why those cannot be used. If a decision relied on a general description of your breathing rather than the actual test numbers, that is worth a closer look. Read 38 CFR 4.96

ILD is a family of scarring lung diseases, and the rating runs on the restrictive breathing numbers: FVC and DLCO. Pulmonary fibrosis, one specific ILD, has its own page on this site with the same formula.

What VA looks at

FVC and DLCO percent predicted, exercise capacity testing, evidence of cor pulmonale or pulmonary hypertension, oxygen requirements, and qualifying service for the presumption.

Common exam and DBQ topics

Breathlessness, dry cough, exercise tolerance, oxygen use, medication and antifibrotic treatment.

Evidence that usually matters

PFT reports, high resolution CT, pulmonology notes, biopsy results when done, deployment records.

Common misunderstandings

ILD is an umbrella, not a single disease. Whatever the specific diagnosis (idiopathic pulmonary fibrosis, hypersensitivity pneumonitis, sarcoidosis with fibrosis), the restrictive formula and the PACT Act presumption work the same for qualifying service.

If a VA decision on this came back wrong

You have three review lanes, pick the one that fits the situation.

Under the Appeals Modernization Act (38 CFR 3.2500), a Higher Level Review or a Board Appeal must be requested within one year of the decision notice. A Supplemental Claim can generally be filed at any time after the decision, but filing any of the three within that one year window is what keeps the claim continuously pursued and protects the original effective date; wait longer and a later award may start from the new filing date instead.

State benefits stack with VA disability

Your rating may also qualify you for state-level benefits.

VA compensation is federal, but every state layers its own benefits on top. Many states reduce or waive property tax for disabled veterans, and many offer license, tuition, or vehicle benefits at various rating levels. The thresholds, dollar amounts, and eligibility rules vary widely from state to state, so the reliable answer is always your own state's guide.
