Q637 – Q637
OHIP Critical Care Code · Schedule of Benefits
When to Use
- Use Q637 as the mandatory tracking code when billing for the administration of the COVID-19 vaccine to patients aged 6 months and older.
- Apply this code alongside the appropriate vaccine administration fee (e.g., G590) to ensure the encounter is correctly captured in the ministry's immunization registry.
Common Pitfalls
- Billing Q637 without an associated administration fee code will result in a rejected claim as it is a non-fee-bearing tracking code.
- Using Q637 for non-COVID-19 immunizations is a billing error; it is strictly reserved for COVID-19 vaccine tracking.
Billing Tips
- Ensure Q637 is submitted on the same claim as the administration fee to avoid reconciliation issues with the provincial immunization database.
