Know what evidence usually matters.
Each checklist below lists the evidence VA commonly reviews for that claim family, in printable form. These are educational lists, not filing instructions; your case may need more, less, or different evidence.
For migraine claims, VA usually needs to understand frequency, duration, severity, whether attacks are prostrating, medication use, and work impact. A migraine log explains the pattern far better than a general statement like 'I get headaches.'
Spine ratings turn on measured range of motion, painful motion, flare ups, and functional loss. The exam captures one day; your evidence has to show the rest of them.
Mental health ratings follow occupational and social impairment, not the diagnosis itself. The evidence that matters most shows how symptoms affect work, relationships, and daily functioning.
Sleep apnea claims live and die on the sleep study and the connection theory. The 50 percent level generally requires prescribed CPAP use, so the prescription paper trail matters.
Hearing claims are measured by audiogram and speech recognition scores, but the exposure story carries the connection. Your MOS may already concede hazardous noise.
Digestive ratings changed in 2024 and now key on symptom combinations and treatment requirements. Document the pattern, not just the diagnosis.
Nerve ratings follow which nerve, which side, and how badly it functions: mild, moderate, or severe. These are commonly missed add ons to spine and diabetes claims.
Skin ratings turn on body coverage percentage and treatment type, and many skin conditions wax and wane. Photograph flares; the exam may land on a clear day.
Joints can carry separate ratings for limited motion and instability at the same time. The exam measures motion with a goniometer; your evidence covers flare ups and function.
Hypertension is rated on blood pressure readings and medication requirements, and it became presumptive for some herbicide exposed veterans under the PACT Act.
