My provider routinely treats hard to treat patients. This provider will take extensive time to consult with the patient's pharmacist, psychotherapist, psychiatrist, and/or primary care physician. Can this provider charge for this extra time (a single session with another HCP can take more than hour). Discussion will usually involve changing medications, cooperating on behavior modification, extensive history in some cases. However, this time sometime does not happen the same day as the E/M. Is there a different code, or just tack on time to the E/M visit?
