Hi, before I begin, I just want to say hi. I've been reading for awhile but haven't posted but one other time and I think that was last week! So I got my approval letter today! YAY! My first question, what does "date of admission/service" mean? It's listing May 28th, 2013 as the date of service. My pulmonologist appointment isn't until June 10th. Not to mention May 28th is next week! This surely can't be my surgery date, can it? It also says that I was approved for services/procedures in an Outpatient Hospital setting. Again, can anyone tell me what that means? It would be wonderful if my doctor's office was 24 hours
