you are correct in your assumption Boondoc. For the CQM's and alternate CQM's presently in Stage 1 MU there is no minimum passing percentage. you could be at 0.0001% for a certain measure and you'll still pass.
They simply want the numerator and denominators, that's it. Very simple.
What is not simple is remembering how AC records them. I made a cheat sheet and taped it to the physical desktop near each computer keyboard in the exam rooms, only for my alternate CQM's and menu items. This helps me remember which ones we are tracking and how to records the data. Since I've been practicing recording the data for these specific measures for several months, it's easy to recall which ones needs CPT codes entered and which needs ICD9 codes entered and which needs the HM checked.
