How VA rates it
Diagnostic Code 6354 · 38 CFR 4.88b
Here is a plain language summary of the rating levels in the regulation. Read the official text for the exact wording.
| Rating | Summary of the criteria |
|---|---|
| 100% | Nearly constant symptoms that almost completely restrict routine daily activities and may occasionally preclude self care. |
| 60% | Nearly constant symptoms restricting activities to less than 50 percent of the pre illness level, or at least 6 weeks of incapacitation per year. |
| 40% | Activities restricted to 50 to 75 percent of the pre illness level, or 4 to 6 weeks of incapacitation per year. |
| 20% | Activities restricted by less than 25 percent, or 2 to 4 weeks of incapacitation per year. |
| 10% | 1 to 2 weeks of incapacitation per year, or symptoms controlled by continuous medication. |
The regulation defines incapacitation as requiring bed rest and treatment by a physician.
