BCBS doesn't require additional certification for telehealth. Typically, not all BCBS plans cover telehealth, but they have stated that they will cover it during this time.

==Update== 3/16/20 at noon Removed update; BCBS rep's statement N/A and superseded by Governor's order

BCBS is not required to expand telehealth coverage for OON providers based on the text of the Governor's order. If you are OON and bill directly, telehealth coverage will be based on client's plan. Alternatively, if you provide the client with a superbill, there is no indication on it whether the session was in person or via telehealth, so this may work. -Brennan
