38 C.F.R. § 3.2501
Except as otherwise provided, a claimant or his or her authorized representative, if any, who disagrees with a prior VA decision may file a supplemental claim (see § 3.1(p)(2)) by submitting in writing or electronically a complete application (see § 3.160(a)) on a form prescribed by the Secretary any time after the agency of original jurisdiction issues notice of a decision, regardless of whether the claim is pending (see § 3.160(c)) or has become finally adjudicated (see § 3.160(d)). If new and relevant evidence is presented or secured with respect to the supplemental claim, the agency of original jurisdiction will readjudicate the claim taking into consideration all of the evidence of record. If new and relevant evidence is not presented or secured, the agency of original jurisdiction will issue a decision finding that there was insufficient evidence to readjudicate the claim. In determining whether new and relevant evidence is presented or secured, VA will consider any VA treatment records reasonably identified by the claimant and any evidence received by VA after VA issued notice of a decision on the claim and while the evidentiary record was closed (see 3.103(c)).
(a) New and relevant evidence. The new and relevant standard will not impose a higher evidentiary threshold than the previous new and material evidence standard under § 3.156(a).
(d) Date of filing. The filing date of a supplemental claim is determined according to § 3.155, with the exception of the intent to file rule found in § 3.155(b) which applies to initial claims.
