How do I fix OHIP error code TM6?

Check the service date and the billing number on the claim. Confirm the registration dates with the Ministry. If the service date is on or after December 1, 2022, bill it under the virtual care rules instead: the Appendix J code plus K300A or K301A, or A101A/A102A, with no OTN service location indicator. Resubmit the corrected claim. Resubmit within three months of the service date if you can. If that window has passed but the claim was first submitted on time, use the Ministry's stale-dated resubmission process: one stale-dated claim file through MCEDT, then an email to ClaimsManagement@ontario.ca with the Error Reports showing the original submission date.

Code: TM6
Description: Registration not in effect on Service Date

Explanation

Updated October 26, 2026

The telemedicine registration wasn't in effect on the service date. Check the registration dates before resubmitting.

What it means

TM6 ("Registration not in effect on Service Date") means the Ministry did not have an active telemedicine registration for this claim on the service date.

TM codes belong to the Ministry's telemedicine error codes (ET1 to ET5 and TM1 to TM8), which were tied to the former telemedicine program. For services on or after December 1, 2022, the virtual care funding framework replaced it: the 'OTN' service location indicator was discontinued (claims using it reject with V73) and OVCP/telemedicine B-prefix codes reject with A3E. Virtual care is now billed with the in-person code plus the K300A (video) or K301A (telephone) modality indicator, or A101A/A102A for limited virtual care.

Common causes

The physician's telemedicine registration had not started or had ended on the service date
The service date was entered wrong
The claim was billed under the wrong billing or group number
