I don't know about resources that can help you get a head start, but from the standpoint of developing HCC risk adjustment tools or RA support tools in SAS, I can tell you that the greatest blind spot is industry knowledge. Any tool or system that you create to interface with the CMS model(s) or CMS reports requires extensive knowledge of the various CMS methodologies and appropriate application. There are potential pitfalls around every corner, and SMEs on the methodologies are hard to find. There are plenty of people in RA jobs that *should* be SMEs on the methodologies, but aren't, and a hefty number of those are quick to give you an ear full of BS that will send you on an endless number of wild goose chases. Most SMEs in RA methodologies that I have encountered are pretty tight-lipped, so it can be a difficult space to navigate. When you find one, keep them close at hand... definitely bring them baked goods on the regular.
