Code: TM4
Description: Non-telemedicine claim already paid for same patient

Explanation

Updated October 26, 2026

A non-telemedicine claim was already paid for this patient for the same service. Check whether both claims cover the same encounter.

What it means

TM4 ("Non Telemedicine Claim paid for same patient") means OHIP already paid a regular (non-telemedicine) claim for the same patient that conflicts with this telemedicine claim.

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 same encounter was billed once as in-person and once as telemedicine
Another physician or group member billed the encounter in person
The service date is wrong on one of the claims
