What 99452 covers
99452 represents the treating or requesting physician’s or qualified health care professional’s work to arrange an interprofessional consultation. That work can include reviewing and preparing the patient’s records, sending the clinical question and relevant information to a consultant, and coordinating the referral. It is used when the clinicians communicate through telephone, internet, or the electronic health record rather than conducting a joint face-to-face visit. The requesting clinician reports their own referral work; the consultant’s assessment and response are a separate service.
Report 99452 when the requesting clinician’s documented work reaches 30 minutes. Record the consultation request, the records and clinical information provided, communication or coordination performed, and total time. CMS assigns the service work and practice-expense values, with different practice-expense inputs for office and facility settings. The related consultant-side codes are selected according to the consultant’s service and time, not the requesting clinician’s referral time.
