Tips for Filing Secondary Claims
- Get a nexus letter: A medical opinion specifically stating your secondary condition is "at least as likely as not" caused by or aggravated by your primary condition is crucial.
- Document the timeline: Show when your secondary condition developed relative to your primary condition. Earlier development strengthens the connection.
- Include research: Medical studies showing the connection between conditions can support your claim. Your doctor can reference these in their nexus letter.
- Be specific on VA Form 21-526EZ: When describing your condition, explicitly state it is "secondary to [your primary condition]" to ensure proper processing.
