Also, most MDs are not happy with the introduction of ICD10, a diagnosis coding system that is more detailed than ICD9. I worked (briefly, just 6 months) in late 2012 for United Health Care, and one of the projects I touched involved some of the crosswalks. I realize how complicated ICD10 is....but that absolutely a more marginal issue compared to a national system that will ultimately impact careers and livelihoods.
There is a belief (certainly anecdotal) at this point that the progression of ACA might ultimately affect (negatively) people wanting to enter the medical profession. That might or might not occur - but I highly doubt we'll have a drop in people entering med school because of ICD10. Apples to little oranges
