Subject      Nurse Practitioners - Referrals

Regulation 552 under the Health Insurance Act was amended on February 11, 1998 to ensure that certain lab tests performed at the request of Extended Class Registered Nurses (ECRNs) - (Nurse Practitioners) are insured services. Referrals on or after February 11, 1998 will be honoured by OHIP.


As a result of an agreement between the Ministry of Health and the College of Nurses, ECRNs who are licensed by the College of Nurses of Ontario and registered with the Ministry of Health can order specific medical laboratory tests.

Nurse Practitioners are registered nurses who have additional nursing education and hold a certificate as an ECRN. This education prepares them to provide the public with services in all five components of comprehensive health services; (health promotion, prevention of diseases and injuries, cure rehabilitation, and support services). Although ECRN’s services are different, they complement those provided by family physicians and other primary care providers.


System changes have been made to the Ministry’s Health Resources Register to accommodate the registration of these practitioners. The nurse practitioners registration numbers range from (722900 - 744292) with a specialty code (76). These services are for referrals only and do not permit claims submission to OHIP by ECRNs for medical laboratory tests.

Lab tests originating in a hospital cannot be billed to OHIP (see Bulletin 4218) and remain the financial responsibility of the hospital.

For OHIP payment of lab tests ordered by ECRNs, the billing provider must be a Private Medical Laboratory (5000 series) and the Fee Schedule Codes must be:
