In point of fact, I have to meet with my local Medisoft guy today to upgrade our office from v9 to v12 because the former does not support NPI numbers. This is going to cost me over a grand, and probably means that whatever Jon does (3-6 months too late for me), I'll probably stay a year with Medisoft to justify the bucks I had to put out because the "coming winter '06" didn't pan out.
