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

Courtney Marie L.
January 3, 2020

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!

SLI Code Indicator Guidelines Reminders
HOP Hospital out Patient Patient seen in a hospital but not admitted – clinic setting. If you are a specialist and see a patient in the emergency department (thus aren’t the emergency doctor) you need to bill as HIP. (EX: A135 K994 K962 E082).
HIP Hospital in Patient Patient located in a hospital or long-term facility with an admission date. Must use facility # for hospital or long-term care facility AT (acute care treatment hospital).
HED Hospital Emergency Department Patient located in emergency department and does not get admitted. Example: if you get called to emergency to assess a patient and the patient goes home.
IHF Independent Health Facility Clinic outside of the hospital, walk in clinic. May or may not have a facility number – doesn’t require one to be added to claim.
OFF Office of Community Physician Private Doctor’s office Office out of a home or private office space, leave the facility # blank
OTN Ontario Telemedicine Network A telemedicine designated room in a hospital or facility pre booked by OTN, use facility # of hospital. When billing OTN the B100, B200 etc. are premiums, you must also bill a consult or assessment.
HDS Hospital Day Surgery Patient undergoes a surgery or procedure and is not admitted to hospital; one day stay. Use facility # for that hospital AM (ambulatory care).
