Looking for some guidance. I am in a family practice office. We have a physician's assistant who is also a chiropractor, but is currently using his PA credential's in our office. He is doing myofascial release and manual traction. A couple of the secondary supervising physicians are DO's and the rest are MD's. If the supervision physician is comfortable co-signing the chart, is there a valid reason for this service to be non-billable? BTW-this is not an insurance issue, it's an auditing issue.
