38 CFR 3.341 - Total disability ratings for compensation purposes.
(a)General. Subject to the limitation in paragraph (b) of this section, total-disability compensation ratings may be assigned under the provisions of § 3.340. However, if the total rating is based on a disability or combination of disabilities for which the Schedule for Rating Disabilities provides an evaluation of less than 100 percent, it must be determined that the service-connected disabilities are sufficient to produce unemployability without regard to advancing age.
(b)Incarcerated veterans. A total rating for compensation purposes based on individual unemployability which would first become effective while a veteran is incarcerated in a Federal, State or local penal institution for conviction of a felony, shall not be assigned during such period of incarceration. However, where a rating for individual unemployability exists prior to incarceration for a felony and routine review is required, the case will be reconsidered to determine if continued eligibility for such rating exists.
(c)Program for vocational rehabilitation. Each time a veteran is rated totally disabled on the basis of individual unemployability during the period beginning after January 31, 1985, the Vocational Rehabilitation and Employment Service will be notified so that an evaluation may be offered to determine whether the achievement of a vocational goal by the veteran is reasonably feasible.
