1What Is the C220 OHIP Code?

The C220 OHIP billing code pertains to special genetic consultations conducted by physicians in the field of Medical Genetics and Genomics. These consultations are extensive, requiring a minimum of 75 minutes of direct contact with the patient, whether with the involvement of their family or not. This code is applied typically in non-emergency hospital in-patient settings.

Genetic consultations under C220 are pivotal in scenarios such as evaluating suspected inherited disorders in adults, or neonates presenting with dysmorphic features. It requires the genetic specialist to perform a thorough assessment and provide a detailed report back to the referring healthcare professional.

Billing for C220 may sometimes be overlooked due to the strict requirement for minimum contact time and comprehensive documentation, including precise start and stop times in the patient record.
