1What Is the H122 OHIP Code?

The H122 billing code is designated for comprehensive assessments and care provided by family physicians in an emergency department setting overnight, specifically between 00:00h and 08:00h. This assessment covers a complete history, examination, and management plan for patients presenting with acute conditions such as chest pain or abdominal pain that cannot wait until morning.

This billing code is essential for ensuring patients receive timely evaluations and care during hours when fewer healthcare resources may be available. Due to its specific timing requirement, it may be easily missed or incorrectly billed if the timing of the service does not align with the stipulated timeframe.
