I don't know of any reg, although there could be one, now. The court ruled, some yrs back, that A&A and HB are an inferred issue, when a claimant is rated 100% for a single disability. This required the VA to decide, at the time of the 100% decision, the A&A/HB issue, in all decisions of a 100% schedular award, for a single disability. The VA failed, to do so, in many claims and that "inferred claim" remains open, with the original claim date as the date of claim. In some cases, if awarded, it could mean a substantial award. I know one vet I've been helping could get 20 yrs retro, if he wins.
