38 CFR 21.186: “Ineligible” status.

(a) Purpose. The purpose of ineligible status is to identify the cases in which a veteran requests services under Chapter 31, but the request is denied by VA, usually, on the basis of information developed when the veteran was in evaluation and planning status.

(b) Assignment to ineligible status. A veteran's case will be assigned to ineligible status following a finding by VA that the veteran is not eligible for or entitled to services under Chapter 31. The finding must preclude all possible Chapter 31 services.

(c) Termination of ineligible status. The assignment of the veteran's case to ineligible status should be terminated if the veteran thereafter becomes eligible to receive any Chapter 31 service. Placement of the case in ineligible status is a bar to reconsideration of eligibility unless a material change in circumstances occurs.
