While no official information has been yet released, based on current information, a COLA adjustment seems very unlikely.
For those of you affected, it may be of interest to note that VA disability benefits have never been increased since their inception. It is inaccurate to speak of an "increase" in benefits based on the annual COLA adjustment. In reality, there is no increase per se, the initial rates are only being adjusted to keep pace with inflation. So, veterans (among others) only see a theoretical status quo in the benefits, never an increase.
