1What Is the C055 OHIP Code?

C055 is an OHIP billing code designed explicitly for Community Medicine consultations, typically used in settings such as hospitals where inpatients are assessed for communicable diseases or exposures that might impact other patients and staff.

In practice, this consultation involves the evaluation of the patient's condition, followed by a comprehensive written report submitted to the referring healthcare professional. This process is critical when the case complexity requires specialized knowledge that the consulting physician possesses.

Due to procedural and documentation requirements, C055 might be missed if the consultation request isn't correctly documented, or if the consultation doesn't meet the criteria for a complex assessment.
