1What Is the C621 OHIP Code?
Understanding C621
The C621 billing code is designed for complex medical-specific re-assessments conducted by allergists and immunologists for hospital in-patients. This code is crucial for managing patients with intertwined allergic and immunologic issues, such as severe asthma interwoven with infections and multiple drug intolerances.
Often, such complex cases are overseen during an admitted hospital stay where treatment decisions require careful consideration due to the overlapping constraints each condition poses on one another. Re-assessing these patients ensures comprehensive care adjustments tailored specifically to their needs.

3Eligibility Requirements
Eligibility for C621 Billing
- General Assessment Requirements: Per the General Preamble GP21, a general assessment involves taking a full patient history, including the presenting complaint, family, past medical, and social histories, followed by a functional inquiry into all body systems. A complete physical exam is generally required unless medically or personally waived.
- Time Recording: OHIP mandates precise documentation of service times. Recording when the assessment starts and ends is essential for billing legitimacy as outlined in General Preamble GP7.
- In-Patient Context: C621 is applicable for services delivered to hospital in-patients with complex medical histories requiring re-assessment during their stay.
- Out-Patient Equivalent: The corresponding service code for out-patient settings is A621.
