The Ontario billing system was designed to only accept 2 digits for the quantity, meaning a service with over 99 units needs to be separated into two claims.
Ie. If you want to submit a procedure and the total number
of units is 110 (basic units + time units), you need to create two
identical claims - one claim with 99 units and a second claim with 11 units.
You will also need to indicate both claims for "Manual Review" under the advanced tab and fax patient notes to OHIP.
