Renoma1, you can get the study guide, that is very helpful.
In order to review my A&P, I studied my Netter’s.
You won’t have to audit the E&M visits, but you will need to understand the key components, how the codes are reported, and the E&M rules. Check out the 1995 and 1997 guidelines from CMS.
CMS also has a list of Rev codes, but I don’t recall that I had to memorize them…only had to know what they were. Your status indicators are in the front of the HCPCS II book. That book has a lot of information you will need to know. Study that book carefully and tab the sections.
