A little late to this discussion, but SC currently has direct access up to 30 days. If 30 days pass by, and the patient is not relieved of their symptoms, then a doctor's referral is required. Also, like the person above, Worker's Comp is very complicated. Some patients try to cheat the system, while others desperately need care and can't get it through worker's comp. WC's only authorize a certain number of visits and in many cases it is hard to treat the patient effectively when they only get 6 visits and these visits are expected to be used in a two weeks time. I work in a OP clinic and I would definitely say at least 1/3 of our intake comes from WC's.
