I've got a couple coding helps as far as the number of systems needed for the Physical Exam to code different levels for new or ret pt's, but I have conflicting data I guess.. I'm trying to figure out how many systems are needed to code 99203? I have a sheet that says 6 systems needed as well as 12 bullets. But another paper I have doesn't mention a # of systems, only the bullets..which says 6-11 bullets. Which is correct?? :/
