If the Decision Review Officer (DRO) overturns an earlier Rating Decision, the DRO will issue a Decision Review Officer Decision with evaluations and effective dates for the overturned items. The DRO Decision looks identical to a standard Rating Decision, with the exception that "Decision Review Officer Decision" appears on page 1.
FWIW, if the veteran disagreed with several items, it's quite possible that a DRO might overturn one or more of the previous decisions yet uphold the previous denials on on others. In that case, the DRO will issue both a DRO Decision as well as a Statement of The Case (SOC) (which continues a denial). In my experience and observations, it's more likely to receive the hard copy SOC before you receive the hard copy DRO Decision because any decision (with award dates, money, etc.) requires a few more desks to rest upon and a few more keystrokes to be done before release to you.
In the above case, there MIGHT be a statement somewhere within the SOC text, somewhat to the effect that " ... other issues claimed will be addressed in a separate decision>"
Was that enough information for you?
