HIM or HSA?

What the heck is that?

So recently I received a letter from a college I applied to for nursing. Well... I didnt get into the nursing program.. something about my core not being completely done. I think maybe they denied all the students not completely done because they had SO MANY applicants. I mean 800 people applied.. and they only take 60 I think? Anyways, they sent me a letter saying I met all the other requirements for a few other programs and I should look into them.

HIM or Health Information Management... I am not too sure what this means.. but from what I goo.gled, I am thinking an office job dealing with medical records and patient history, with saleries from $37,000-161,000. WHAT?!? Uh yes please! The college even has it listed that more than half their graduates start out making $55,000, and within 5 years they are making $65-75,000. Umm.. I think I can do that and forget nursing. I mean I can still be in healthcare with this :)

HSA or Health Services Administration... I feel like its almost the exact same as HIM. And the pay is just about equal. I cant find the exact difference yet.. but I am still researching..

Umm... did I miss something? All I have heard since high school is nursing is the only way to go in healthcare. But these sound like great jobs.. in fact.. a little too good to be true. =/ It even says these fields are tripling each year. Next Wednesday, I am meeting with an advisor about the HIM program and I am going to figure exactly what it is. I also want to know exactly what needs to happen for me to get in :)
