I have another question hopefully this will clear up the CONFUSIONS in my head!!1

So, if patient has a detail history, EPF exam, Moderate risk – I can code a 99214
other example is Detail history, Problem Focus exam and Moderate risk – I can throw out the to lowest and code the highest correct?

when exactly do i use that rule? is it just when I have 3 different levels of exam ? did i just answer my question? HELP!
