Going through a coding program at a CC?

Since I really want to work from home I was wondering if it would be a good idea to go through the year-long medical coding and medical reimbursement program at the local community college (well, it isn't really "local" but it's the closest one). When I worked in home health we looked up codes to go with our patient's dx and I didn't mind doing this at all. In fact, I would rather have stayed there doing codes all day as having to go out to patient's homes.

Anyway, this program says it prepares you for national certification.

Does this sound like a good idea? I would hate to waste a year on something that really won't be beneficial. I can't afford it.
