You may qualify for what's called Individual Unemployability, but only if you have disability related to your service in the military, a service-connected disability. This means you may be able to get disability compensation or benefits at the same level as a Veteran who has a 100 % disability rating.
Well, no can do then. My brother was wounded during service though and he still has a disability from his time in the army. His disability rating is only at 60 % though, does that mean he won't qualify for benefits either, even if he needs to be in hospital a lot?
If you need to be in the hospital often, you may qualify at a lower disability rating.
