Quick answer
Medical evidence can come from VA, military, or private clinicians and facilities. It may prove that a condition exists, show severity over time, document treatment, or offer a medical opinion. A record mentioning a condition is not automatically evidence of its cause or current rating level.
Common types of medical evidenceDetails
- Office and specialist notes, emergency records, hospital summaries, operative reports, therapy notes, and medication history.
- Diagnostic testing such as imaging, laboratory work, audiology, pulmonary testing, nerve studies, and sleep studies.
- C&P examination reports and Disability Benefits Questionnaires.
- Medical opinions addressing direct service connection, secondary causation, or aggravation.
- Records documenting assistive devices, work restrictions, flare patterns, or adverse medication effects.
Read the record for substanceDetails
- Diagnosis: Is it confirmed, provisional, ruled out, or merely listed in history?
- Timing: When did symptoms, diagnosis, and treatment begin?
- Severity: Are frequency, duration, measurements, and functional effects recorded?
- Reasoning: Does the clinician explain a cause, or only repeat the history provided?
- Consistency: Do later tests or opinions change the picture?
What to includeDetails
- Use records close enough in time to answer the question being decided.
- Include the pages containing the relevant assessment, testing, plan, and context—not a cropped sentence that changes meaning.
- Identify provider, facility, and date.
- For a long record, create a page index or short evidence note rather than altering the document.
Common questionsDetails
- Are treatment notes the same as a nexus opinion? — No. A note may document history without adopting a medical conclusion about cause.
- Are private records weaker than VA records? — No automatic rule makes them weaker; competence, factual accuracy, reasoning, and relevance matter.
- Does no treatment mean no disability? — Not necessarily. But treatment gaps may affect how the history is understood and should be addressed honestly.
