DrJJ -
I think you need to consider your option of tech support - although you may not use it much you are going to get bug fixes, ICD 9 and CPT upgrades (and this is important, particularly as we enter ICD10) and any upgrades as they appear. I do think even specialists can meet at least year 1 of MU with some work which would pay for 18 years of support.
I find it not that hard to do ht / wt - but if it really does not matter to you then at least put in stated height which calculates BMI.
Don't get discouraged - I do think that support is worth 1,000 per year even though I realize it is hard to make out the check at the time.
