Hello,
I have been in private practice for awhile but always with other groups. 5 years ago I went off on my own and started my own mental health counseling business. I established it (the business) as an LLC using my individual EIN
Using an individual EIN number and an individual NPI number. After 5 years, and in-network with up to 20 insurance/EAP's companies I am moving to change the individual practice into a group practice adding another licensed therapist.
I'm unsure if I need to establish a new group EIN tax number AND a new NPI - 2 GROUP number. Or just an NPI or a new tax EIN.
Please help!
