Yes, you need a seperate DEA in each state, but sometimes the site will pay for it. Also if you finish up an assignment, you can just transfer the DEA from state to state. I have 3 DEA numbers and am letting one lapse because I only have a need for two at the moment. I do this at a CMHC which has nursing staff, other onsite psychiatrists, social workers etc. If I need to, I file petitions/baker acts to send them to the hospital involuntarily (for suicidal intent/cutting) and depending on the state, the police comes to get them for transport. I don't want to divulge any specific companies because these jobs can be hard to find. I ask to be paid as a contractor by the hour, whether the patients show or not. I don't have to deal with collections. A lot of patients are uninsured. I also don't rx stimulants at all and taper pts off benzos when I see someone is on them. This mentality can create a challenge in finding a job.
