## Abstract

This document amends the Department of Veterans Affairs (VA) adjudication regulations concerning presumptive service connection to reflect a statutory presumption that a chronic disease that preexisted the veteran's entry into military service but was first manifest to a 10-percent degree of disability within a specified period after service was aggravated by the veteran's military service. This amendment is necessary to make the regulations conform with the statute and the Court's decision.
