1What Is the K736 OHIP Code?

K736 is an OHIP billing code designated for referring physicians participating in CritiCall telephone consultations. These consultations occur typically in emergency departments or hospital urgent care clinics, where timely specialist advice is crucial for patient management or determining patient transfer needs.

Family physicians use this code when they seek the expertise of a consultant physician via a telephone consultation facilitated by CritiCall Ontario. This setup allows immediate access to specialist input, which is vital for quickly addressing the often critical conditions presented in emergency settings.

Often missed, the K736 billing opportunity may be overlooked in the rush of emergency settings due to uncertainty about the specific requirements or confusion with similar codes, such as K732.
