OHIP Billing Support – Don’t Forget the Service Location Indicator

What is the Service Location Indicator?

The Service Location Indicator (SLI) is a mandatory field that must be filled out on all billing software that electronically submits claims to OHIP. The SLI field simply lets OHIP know where the patient is being seen. In total, there are 8 options to choose from and each option is represented by a 3-letter code.

Billing Tip: Our OHIP billing experts find that a lot of submission errors are due to the incorrect use of an SLI code.

Therefore, to make things easier, we've created a reference chart of all SLI codes so you can quickly find the one you’re looking for and avoid getting submission errors once and for all!
