I'm going to teach myself, then take a 4 day coding bootcamp. I am about 90% sure I can get a job doing this with the CPC-A certificate at the hospital I work for, and need to do this due to transcription going to voice recognition soon. :o) Thanks everyone in advance! I realize that, but I'm talking about workbooks and study guides to learn how to code properly - rules & regulations, formats, types of insurance and modifiers. Thanks!
