I do not know what you know or you think you know. I do know that whatever you need to know you will know if you really want to know.
Anyway, I am talking about things like if you see Pt for DM and ST you should put code for BS 82947 before 250.00 and code for strep 87880 before lets say 463. You do it wrong and they will pay for the visit but will deny few bucks for BS and $12-15 for strep.
