38 C.F.R. § 14.807
(f) Normally, written demands or requests allowing reasonable lead time for evaluation and processing are required. However, in emergency situations where response time is limited and a written demand or request is impractical, the following procedures should be followed:
(2) If the responsible VA official concludes that the demand or request, or any portion of it, should be granted (after considering the factors listed in § 14.804), the responsible VA official will then orally advise the requester of the determination in accordance with the procedures provided in § 14.807(c), including any limitations on such testimony or production of records, and seek a written confirmation of the oral demand or request. The responsible VA official will make a written record of the determination made concerning the oral demand or request, including the grant or denial, the circumstances requiring the procedure, and the conditions to which the requester agreed.
