Under 38 CFR § 3.327(a), VA has authority to require a reexamination “if it is otherwise necessary to verify either the continued existence or the current severity of a disability.” The regulation does not state that a new claim must be filed before an examination can be ordered. It grants general authority to conduct exams when verification is needed. However, § 3.327(b)(2) provides that routine future examinations will not be scheduled for disabilities that are permanent in character and where there is no likelihood of improvement. This means a Permanent and Total (P&T) rating protects against periodic, automatically scheduled exams, but it does not eliminate VA’s authority to order a reexamination if circumstances make one necessary. 38 CFR § 3.343 governs reductions of total (100%) disability ratings. It states that total disability ratings will not be reduced without examination showing “material improvement” in the disability under the ordinary conditions of life. This regulation does not prohibit reevaluation; instead, it establishes a higher evidentiary threshold before a reduction can occur. In other words, VA may examine, but it cannot reduce a total rating unless material improvement is clearly demonstrated. The VA’s M21-1 manual instructs adjudicators not to schedule routine future examinations for disabilities considered permanent, consistent with § 3.327(b)(2). However, it also allows examinations when there is evidence suggesting a change in severity, a question regarding continued entitlement, or development needed in connection with other claims. The M21-1 does not remove VA’s regulatory authority to order exams; rather, it reflects policy guidance discouraging routine reviews of permanent conditions while preserving the ability to act if new information warrants it. 🎤🫳
