1What Is the C050 OHIP Code?

What is the C050 Billing Code?

The C050 OHIP billing code is used for special community medicine consultations rendered by specialists to hospital in-patients. This code is primarily used in scenarios involving public health implications, such as outbreak investigations or exposure cases.

During such consultations, the community medicine specialist assesses the patient and addresses broader public health risks related to the patient's condition or admission, usually requiring a minimum of 50 minutes in direct contact.

This code is often missed due to its specific requirement for both patient assessment and public health evaluation, which must be documented in accordance with OHIP’s guidelines.
