1What Is the C626 OHIP Code?

What is C626?

The C626 code is designated for repeat consultations in the field of Allergy and Immunology, specifically for in-patient settings. These repeat consultations are necessary when a patient has further allergic reactions or when the initial treatment plan needs adjustment due to ineffectiveness.

This code is frequently missed due to misunderstandings about the conditions that warrant a repeat consultation, or failure to secure a new written request from the referring provider.
