Veterans may use the 4138 form to include:

  • Personal statements about medical conditions
  • Explanations of service-connected events
  • Descriptions of symptoms and daily impact

The statement should be clear, honest, and as detailed as possible.

These supporting statements are often referred to as lay statements.
