38 C.F.R. § 19.38
When a case is remanded by the Board of Veterans' Appeals, the agency of original jurisdiction will complete the additional development of the evidence or procedural development required. Following completion of the development, the case will be reviewed to determine whether the additional development, together with the evidence which was previously of record, supports the allowance of all benefits sought on appeal. If so, the appellant and his or her representative, if any, will be promptly informed. If any benefits sought on appeal remain denied following this review, the agency of original jurisdiction will issue a Supplemental Statement of the Case concerning the additional development pertaining to those issues in accordance with the provisions of § 19.31 of this part. Following the 30-day period allowed for a response to the Supplemental Statement of the Case pursuant to § 19.52(c) , the case will be returned to the Board for further appellate processing unless the appeal is withdrawn or review of the response to the Supplemental Statement of the Case results in the allowance of all benefits sought on appeal. Remanded cases will not be closed for failure to respond to the Supplemental Statement of the Case.
