I'm not sure what you mean by 'opening package'. Do you mean for a new patient who is starting treatment?
For Workers' comp you should contact the state comp board to find out if they need to get credentialed, or how the state of Michigan handles workers' comp. Some states the provider doesn't need to do anything, others they need to fill out an app, and others must be in a network of chosen providers that they have to request entry into thru the carrier. It varies by state.
