By request (check the comments), here is the latest Pediatric E&M Distribution data from PCC. You can't get it much fresher than this - a few million E&M CPT codes, from May 2007 to May 2008. I had a good, in-depth, analysis earlier this year.
I've had a request to post some information about the 2008 RVU impact, but I've decided to wait a day or two for the dust to settle about the latest news. Hope you don't mind.
