I personally think that the current wording on the severity codes is not intuitive and should be modifiable. To me green means go, yellow means wait for now, red means stop.
This is how we interpret them in my practice. Green tx plans means go - schedule. Yellow means it is pending some details, needs counseled, etc. Red means stop, just a placeholder for future codes etc.
An easy patch would be to add a feature which allows each practice to completely customize the wording or delete it entirely.
Alternative please allow this to be hidden from printed tx plans. Currently there is no option to hide it. Thus when I have a green tx plan which means go, it will say "optional" on a printed tx plan. Not good.
