1What Is the C655 OHIP Code?

What is OHIP C655?

The OHIP C655 billing code allows hematologists to claim for limited consultations provided to non-emergency hospital in-patients. This code offers a flat fee, acknowledging services that are less demanding than full hematology consultations. It's typically used for presenting a short, focused opinion on specific aspects of care, such as a transfusion or anticoagulation decision, rather than conducting an exhaustive work-up.

Limited consultations are often overlooked due to physicians defaulting to more comprehensive codes or misunderstanding the precise eligibility requirements. Understanding its specific application can ensure accurate and efficient billing.
