helpful link to NHIC document
Thanks to Laura for that helpful link to the NHIC document, which spells out the fact that you can use 1995 or 1997 on any given note. I agree that it is a good idea to be consistent within one office, but on the other hand, in my job, the provider codes the encounter and I review it. My goal is to agree with the provider, as long as I am confident I can justify the level based on 1995 or 1997. And the NHIC document backs me up, because it says that the auditors are supposed to use whichever set of rules favors the provider.
One of the tricky aspects of 1995 exam rules is what is an "extended exam of affected system". I am not sure what the minimum should be, but there are times when it is clear that the exam was extended and so I feel I can justify "detailed" exam. Strangely, the comprehensive exam in 1995 is less subjective - 8 or more systems examined.
Another thing I like about 1995 rules is that an instructor once gave me an ingenious 3.5" by 8.5" card, which acts as a complete set of rules for all office visits, consults and inpatient visits, including coding by time. She gave it freely and claimed no copyright on it. One of these days I will recreate it so I can give it out electronically.
