What type of evidence is allowed during a higher-level review in the AMA process?

During a higher-level review in the Appeals Modernization Act (AMA) process, any relevant evidence is allowed. This includes new evidence that may not have been previously considered, as well as evidence that supports the existing claim. The purpose of the higher-level review is to provide an opportunity to reconsider the original decision with potentially new or supporting information, enhancing the veteran's chance for a favorable outcome.

The flexibility to submit any relevant evidence ensures that all pertinent information can be taken into account, allowing the reviewer to make a more informed decision. Such an approach reflects the intention of the AMA to create a more veteran-friendly appeals process by accommodating additional supporting materials that could bolster the claim.
