You may not moonlight/perform off-duty employment (ODE) unless your commander (Bn-level or higher) authorizes you to. You can be limited in your number of hours & where you perform your ODE. You are subject to recall and termination of your ODE, at any time, for any reason. You (or your employers) may not accept payment from TRICARE eligible patients you take care of. You may not use your military exempt DEA number to write for controlled substances at your ODE. You need to arrange for your own malpractice insurance to cover your ODE.
I think this covers the major stuff.
