((d))
((1)) The Board of Veterans’ Appeals shall remand a claim to direct the agency of original jurisdiction to obtain an advisory medical opinion from an independent medical expert under this section if the Board finds that the Veterans Benefits Administration should have exercised its discretion to obtain such an opinion.
((2)) The Board’s remand instructions shall include the questions to be posed to the independent medical expert providing the advisory medical opinion.
