This is the first claim for service connection for a condition. VBA is requesting evidence from the clinical interview and examination as to whether there is a current physical or mental disability, evidence of an event, injury, or disease in service, and evidence of a connection between the current disability and the event, injury, or disease in military service.

This is a claim for an increase in disability and requires evaluating a condition that is already service connected. VBA is requesting evidence from the clinical history interview and examination as to whether the disability has worsened since the last C&P examination.

A supplemental claim can be a reopened claim or a review claim.

Reopened: This is a claim already filed that VA could not grant and the decision is over one year old. VBA received new evidence that has never been considered but that pertains to the issue claimed. VBA is requesting clinical evidence to help adjudicate the reopened claim.

Review: This is a request from VBA to evaluate a disability that is already service connected to determine whether the current disability rating is still appropriate. For certain disabilities that are not static, VA is required to periodically reevaluate the disabilities' functional impact on the Veteran.
