I'm a newly graduated NP in the process of looking for my first NP job in Texas. Recently I was asked by a possible employer about NPI, DEA, DPS, and Medicare numbers, and I'm realized I'm confused about the process of getting these numbers. Can I get any of these numbers on my own before signing a collaborative agreement? I was under the impression I need to have a collaborating physician for all of these. Also, if anyone could clarify the steps/timeline for getting these numbers I would really appreciate it (e.g. what do you need to get first etc.). Thank you!!
