I have two notes to add about the CPC to Linda's post, from questions I frequently see from students.
1. The CPC-A and CPC are the same credential. It's the same test, the same certification. The only difference between the two is the lack of on-the-job experience.
2. We recommend you take the CPC as soon as possible after Module III, but we don't require that. Most students find it helpful to take it quickly while Module III's material is still fresh in their minds.
It's not possible for everyone to take it right then, however. AAPC proctors their own tests, unlike AHIMA, so you're dependent on there being a test offered in your area or an area you can reasonably get to soon after you finish Module III. For some students, it may be months before a test they can get to is available. Some also choose to wait for financial, personal, or work-related reasons until they graduate the entire course before taking the CPC, and that's okay.
You will retain access to the Coding Certifications area after you graduate, and the instructors remain available to answer graduates' questions as well, so you still have the school's support even if you do not take a certification exam right away when it's first possible for you to do so!
