For providers that enroll solely to order or refer services using the CMS-855O, it is a national enrollment. When you relocate to another state, you are not required to dis-enroll from the current state and re-enroll in the new state. The contractor that maintains your CMS-855O enrollment in PECOS is responsible for processing change of information applications including relocating to a state outside of their jurisdiction and updating the current enrollment with any new licenses obtained in the new state.
