Answer: Reporting 99371-99372 (Telephone call by a physician to patient or for consultation or medical management or for coordinating medical management with other healthcare professionals [e.g., nurses, therapists, social workers, nutritionists, physicians, pharmacists] ...) probably isn't appropriate for these services, because the activities you describe are generally included in the emergency department E/M service.
Most payers do not pay for telephone calls. And the physician must meet the requirements for a consult before billing codes 99371-99372, which is highly unlikely in the ED.
