Hi, I'm a newly certified CPC-A and during my job search I came across a position needing someone familiar with CPT-4 and ICD-9. I have never heard of CPT-4 so on the application I said that I wasn't familiar with it. My CPT book is 2010, please tell me CPT-4 is something different than that. ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
