Pleuritis (Pleurisy and Pleural Disease) VA Disability Rating

Diagnostic code 6845
By the editorial deskUpdated Jun 13, 2026Sources verified Jun 13, 2026
Presumptive under: PACT Act
Quick summary
Chronic pleural effusion or fibrosis is rated under diagnostic code 6845 using the restrictive lung formula, from 10 to 100 percent based on FVC, DLCO, exercise capacity, and complications. Pleuritis 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 6845, using the criteria in the rating table below.
  • The percentage assigned turns on FEV-1, FEV-1/FVC, and DLCO.
  • 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 6845 for Pleurisy Residuals and Restrictive Lung Disease. Those are distinct conditions with their own pages. This page covers Pleuritis (Pleurisy and Pleural Disease) 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. Pleuritis 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 6845.

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 6845.

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

Inflammation or scarring of the lining around the lungs restricts how much air you can move. The rating follows the restrictive breathing numbers, the same formula used for interstitial disease.

What VA looks at

FVC and DLCO testing, imaging showing pleural thickening, effusion, or fibrosis, and qualifying service for the presumption.

Common exam and DBQ topics

Chest pain with breathing, breathlessness, history of effusions or procedures.

Evidence that usually matters

Chest imaging, PFT reports, pulmonology notes, records of pleural procedures such as thoracentesis.

Common misunderstandings

A single bout of pleurisy that resolved is unlikely to rate. What the schedule compensates is chronic pleural disease that restricts lung function, shown on testing.

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.
