I appreciate your point but I do not think it contradicts the numbers - going to ER and getting a green triage means that the triage personnel determined that it is not an emergency. According to 2013 National Institute of Health study put the median cost of ER visit at $1,233. In 2015 there was over 130M ER visits. Lets arbitrary assign the cost of interacting with the Triage nurse at the ER to $233 ( which is insane lets do it anyway), then the pool of cost overtriage 130M * $1000 which is $130B. Of those even triaged up 70% is a green triage, which makes it $91B. If we are to make an assumption that for non-emergencies addressed by ER cost only twice as much non ER then simply by sending people to a regular doctor after people are getting a green triage one realizes savings of $91B/2 = $45.5B
