38 C.F.R. § 3.327
(a) General. Reexaminations, including periods of hospital observation, will be requested whenever VA determines there is a need to verify either the continued existence or the current severity of a disability. Generally, reexaminations will be required if it is likely that a disability has improved, or if evidence indicates there has been a material change in a disability or that the current rating may be incorrect. Individuals for whom reexaminations have been authorized and scheduled are required to report for such reexaminations. Paragraphs (b) and (c) of this section provide general guidelines for requesting reexaminations, but shall not be construed as limiting VA's authority to request reexaminations, or periods of hospital observation, at any time in order to ensure that a disability is accurately rated.
(Authority: 38 U.S.C. 501)
(c) Pension cases. In nonservice-connected cases in which the permanent total disability has been confirmed by reexamination or by the history of the case, or with obviously static disabilities, further reexaminations will not generally be requested. In other cases further examination will not be requested routinely and will be accomplished only if considered necessary based upon the particular facts of the individual case. In the cases of veterans over 55 years of age, reexamination will be requested only under unusual circumstances.
Cross Reference: Failure to report for VA examination. See § 3.655.
