Y879 – Y879
OHIP Other Code · Schedule of Benefits
When to Use
- Use Y879 as a mandatory diagnostic code when billing for the administration of the COVID-19 vaccine to indicate the service provided.
- Apply this code when submitting claims for the COVID-19 immunization encounter fee to ensure the claim is correctly identified by the Ministry for tracking purposes.
Common Pitfalls
- Failing to include Y879 on the claim will result in the rejection of the associated immunization fee code, as the Ministry requires this specific diagnostic code for all COVID-19 vaccine administration claims.
- Using Y879 in conjunction with other non-immunization related services on the same claim can lead to processing errors; it should be reserved for the specific encounter related to the vaccine administration.
Billing Tips
- Ensure Y879 is linked to the specific fee code used for the vaccine administration (e.g., G593 or G594) to satisfy the Ministry's validation requirements for COVID-19 claims.
