G593 – COVID-19 vaccine
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Administration of a COVID-19 vaccine. This service is an add-on (+) to another service. If the immunization is the sole reason for the visit, G700 may be added, limited to once per patient per day. This procedure can be delegated to a trained employee under specific conditions as per pages -.
When to Use
- Use G593 in addition to an assessment code (e.g., A007) when a patient presents for a medical issue and receives a COVID-19 vaccine during the same encounter.
- Use G593 combined with G700 when the patient attends the office exclusively for a COVID-19 vaccination with no other assessment or counselling performed.
Common Pitfalls
- Billing G593 as a standalone service without adding G700, which results in the loss of the $5.60 visit premium for sole-purpose immunization visits.
- Attempting to bill G700 alongside an assessment code (e.g., A007) or consultation, which will trigger a rejection because G700 is only payable when the vaccine is the sole reason for the visit.
Billing Tips
- Unlike most counselling codes, G593 is explicitly permitted on the same day as K013 or K033, allowing you to bill for both the counselling session and the vaccine administration.
