I was discussing medical coding with Nicole Zepper earlier this week and decided that I would really like a simple guide to medical coding systems. So this week I made one, and you can find it here: http://docs.google.com/Doc?docid=0AUpoyOWln5G0ZGd4djU2M3dfMjhmeHByenBkZA&hl=en. It should be editable by anyone, so feel free to correct or add to it as you see fit.
Liz also wrote a very good blog post a while back about this that contains additional information on finding healthcare costs: http://blog.lib.umn.edu/staff/biomedref/archives/001255.html. I'll integrate her information into my document in the future.
Happy New Year!
