I'd like to know as well. What is the procedure for obtaining these advantages? Could you elaborate on the 100% rating and why it occurs?
Let's say your disability rating begins at 30%, and you need a surgery for complications.  Since the doctor wouldn't know if the surgery was successful until a certain time has passed you would be given a temporary 100% disability rating for 3 months
ok, what if I need 1 month and I'm good?
The temporary 100% rating may continue for 1 to 3 months depending on your case. You may be able to get an extension for up to 3 more months if your case is severe.
