To be actionable, I felt it more useful to look at healthcare costs by specific clinical condition, rather than by the general disease groupings of my last post. Here is the graphic I came up with (excluding mental disease categories for now).
The 8 red dots represent clinical condition codes with annual expenditures each in excess of $20 Billion. The green dots represent 14 clinical condition codes with costs in excess of $10 Billion (but less than $20B).
