The Ministry of Health (ministry) is making changes to the Ontario Health Insurance Plan (OHIP) Schedule of Benefits for Physician Services (Schedule) to help streamline patient care and support scope of practice expansions.

These changes will enable physician payment for the following:

  • Diagnostic procedures, including physician interpretation, ordered by nurse practitioners and oral and maxillofacial surgeons when ordering the diagnostic procedure is within their respective scope of practice, and
  • Specialist consultation services requisitioned by hospital-based dentists as required to support insured dental procedures.

New general preamble section

Effective July 1, 2023, information regarding OHIP payment to physicians for diagnostic procedures ordered by persons other than a physician will be in the Schedule in a new section of the General Preamble titled “Diagnostic Procedures Ordered by Persons Other Than Physicians”.

Insured services requested by nurse practitioners and dental surgeons

Effective July 1, 2023, the following services are insured under OHIP:

Diagnostic Procedures

  • Magnetic resonance imaging (MRI) scans ordered by oral and maxillofacial surgeons
  • MRIs and computed tomography (CT) scans, as well as x-rays and ultrasounds for any region of the body, when ordered by nurse practitioners

Consultation Services

  • Specialist consultation services requisitioned by hospital-based dentists when required to support insured dental procedures

Claims submission requirements

The insured services described above should be claimed using existing fee codes in the Schedule and include the OHIP Billing number of the provider referring/ordering the service.

Physicians are asked to hold claims for MRI services ordered by oral and maxillofacial surgeons until August 1, 2023, to allow time for updates to the medical claims payment system.

Consults requested by dentists will continue to reject “V09 – Invalid Referring Number” until additional system changes can be completed.

For consult services rendered on or after July 1, 2023, please flag the claim for manual review and reference this INFOBulletin.

A future INFOBulletin will be published to advise physicians when the system changes are complete and the claims for consults requested by dentists can be submitted for processing without flagging the claim for manual review.

Providers requiring an OHIP Billing number should submit the form Application for OHIP Billing Number for Health Professionals to
