- Telemedicine Premium/Tracking Code Missing
Explanation
Updated October 26, 2026
ET4 means a telemedicine claim is missing its telemedicine premium or tracking code. Check how the visit should be billed.
What it means
ET4 (Telemedicine Premium/Tracking Code Missing) means the claim was set up as a telemedicine claim but did not include the telemedicine premium or tracking code the program needs.
The July 2026 Schedule of Benefits has no telemedicine (OTN) fee rules. Virtual care is now billed with the in-person code plus K300A (video) or K301A (telephone), or with A101/A102 for limited virtual care.
Common causes
- The OTN service location indicator was used without a telemedicine tracking code
- An older telemedicine billing template still in use
How to fix it
- Check whether the claim was meant to be telemedicine.
- For virtual visits, bill under the current virtual care rules: the in-person code with K300A or K301A, or A101/A102. Remove the OTN service location indicator.
- Resubmit the corrected claim within three months of the service date. If that window has passed but the claim was first submitted on time, use the Ministry's stale-dated resubmission process.
