I use EZClaims for billing. Because AC does not easily import into EZCLaim without errors, I have developed middleware for scrubbing claims. In the meantime, all the data I gathered through that system has made it possible to manage real mailing lists, missing fee tickets, new patient letters, and other financial reporting. I've actually integrated reports from EZClaim and the clearing house so I can close the loop about actual receivables, contractuals, and AR. Also integrated into my middleware system is disease tracking (A1C to goal, last TSH, etc). All this is just by way of explanation that I don't know what PM enhancements will do for me.
I think the ARRA objectives are good drivers for quality. When I was heading the medical group, we struggled for years just to do chronic disease management - three years just to get diabetes done correctly. Most of MU quality requirements are already done in my practice, very time consumingly by manual labor. If the MU-aware AC 6.0 makes the task easier AND I get paid for all the work, I definitely wanted it yesterday.
