Counselor A invites another counselor, Counselor B, to use her office space when it is free and will funnel some of her referrals to Counselor B. Counselor A tells me, her biller, that Counselor B will be seeing the clients and the sessions will be billed under Counselor A. Not under the business or the facility, but using Counselor A's name, tax ID and NPI with no mention on the claim that Counselor B actually saw the client.
