For other carriers other than Medicare, Medicaid, and Tricare can you bill any physician that is in the office that day as their supervising physician. For example: Dr. A is the PA's supervising doctor and he is out of the office can she use any other physician that is located in the office or does it strictly have to be under the supervising physician?![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
