1What Is the K735 OHIP Code?

The K735 billing code is used for telephone consultations where a consultant physician provides advice to another physician, usually when the consultant is on emergency or urgent care duty. This service is crucial in ensuring continuity of care, especially for rural or remote family physicians who may require immediate input on managing a patient.

This code allows for remuneration for the consultant's time in reviewing patient data and providing recommendations over the phone. It differs from in-person or video consultations in that it is specifically designed for the dynamic and immediate communication needed in urgent or emergency settings.

It is important to note that K735 is often missed because physicians may not be aware it can be billed separately from other in-person patient interactions or services provided on the same day.
