The section says "new medical evidence being acquired." So it's not like you are bringing in a fourth doctor because you don't like the third doctor's opinion until you keep stacking opinions until you get one you like. You have a new test or something new has come up that is new that three doctors who have looked at it already haven't seen. It's a new piece of evidence that might cause them to change the way they look at things. It's not a third or fourth or fifth or sixth opinion.
