Interprofessional consultation
About 99451: Interprofessional consultation with written report
A consulting physician reviews a patient's clinical information and sends written assessment and recommendations to the treating professional after at least five minutes of consultative work.
A treating physician or other qualified health care professional may request a specialist’s advice about a patient’s clinical question without arranging a patient visit with that specialist. The consultant reviews the relevant record and provides an assessment and recommendations in a written report. For example, a primary care physician might ask a cardiologist to review a patient’s symptoms and available cardiac test results and advise on next steps. The service is an exchange between professionals, not a face-to-face consultation with the patient.
Report 99451 when the consultative physician provides the written report and performs at least five minutes of medical consultative work. The record should identify the request and clinical question, information reviewed, consultant’s assessment and recommendations, written communication to the treating professional, and time spent. Document the patient’s consent to the interprofessional consultation. Distinguish this service from codes 99446–99449, which include verbal as well as written communication and use specific time intervals.

99451 billing questions
When should 99451 be chosen instead of 99446?

Is patient consent part of the documentation?
Yes. Document the patient’s consent to the interprofessional consultation.
Can 99451 be reported for less than five minutes?
