Emergency Medicine OHIP Billing Codes
Emergency department and hospital physicians in Ontario bill OHIP using H-prefix codes from the Schedule of Benefits. H001A covers standard emergency assessments; H002A covers complex presentations.

The April 2026 Fee Schedule Master contains approximately 200 active H-prefix codes.
H-Prefix Code Structure
H-prefix codes in the OHIP fee schedule cover: emergency assessments (H001–H009), hospital consultations (H3xx), trauma assessments (H112, H113), critical care, and institution-specific services.

Emergency Medicine OHIP Billing — FAQ
What OHIP billing codes do emergency department physicians use?
Emergency department physicians primarily bill H-prefix codes from the OHIP fee schedule. H001A is the emergency department assessment. H002A covers complex ED assessments. H113A and H112A cover trauma assessments. ED physicians may also bill A-prefix assessment codes when patients are seen in an outpatient or office context. All H-prefix consultation codes require a referring provider number on the claim.
Do emergency medicine OHIP claims require a diagnostic code?
Most H-prefix emergency medicine codes require a diagnostic code (dx) on the OHIP claim per MCEDT spec section 4.9. A small number of H-codes are exempt — these are listed in the Schedule of Benefits. Using the filter above, check the "Requires Dx code" checkbox or expand any code to see its diagnostic code requirement.
What is the H-prefix in OHIP billing codes?

H-prefix codes are used by physicians providing care in hospital settings — emergency departments, inpatient units, and outpatient hospital clinics. Consultation codes with H prefix require a referring provider number. The fee schedule contains approximately 200 active H-prefix codes as of April 2026.
