Which vendors serving the ICD-10 segment would I visit at HIMSS 12?

I'm interested in ICD-10 with a specific focus on its impact to healthcare payers, providers who bear risk and the software vendors providing solutions to those two healthcare segments. I want to learn about new entrants to the ICD-10 healthcare solutions marketplace; not so much about the large behemoth vendors and Big 4 consulting firms that don’t impress me as offering leading edge products and ideas; or if they do, their entry cost is prohibitive for many small and medium sized firms.

Here are some specific vendors whose products and services I’m looking forward to learning more about during the HIMSS 2012 conference in Las Vegas
