1What Is the C415 OHIP Code?

What is C415?

C415 is a billing code used by gastroenterologists in Ontario for consultations provided to non-emergency hospital in-patients. This service involves an in-depth assessment requested by another healthcare professional to address complex or serious conditions like gastrointestinal bleeds, decompensated liver disease, or inflammatory bowel disease flares.

Consultations are pivotal in shaping patient management plans by offering clinical insights and recommendations based on specialized knowledge in gastroenterology. The C415 code ensures that gastroenterologists are compensated for these critical evaluative services.

The C415 code requires precise documentation and adherence to eligibility criteria, and it may be commonly overlooked due to misunderstanding of these detailed requirements.

Can the C415 code be billed twice in a 12-month span?
Generally, no. However, if the second service is for a hospital inpatient between 12 and 24 months after the first, it may qualify.
What conditions typically justify a gastroenterology consultation using C415?
Conditions like gastrointestinal bleeds, decompensated liver disease, or inflammatory bowel disease flares typically qualify.

Because C415 applies to consultations for hospitalized patients needing in-depth gastroenterological assessments.
Can a consultation initiated by a nurse practitioner be billed under C415?
