Referral requiredFrom: Physician, NursePractitioner, DentalSurgeon

A new written request from a referring physician, nurse practitioner, or dental surgeon is required.

The consultant must prepare a written report including findings, opinions, and recommendations to the referring provider.

The consultant is required to perform a general, specific, or medical specific assessment, including a review of all relevant data.

A copy of the written request for the consultation, signed by the referring physician, nurse practitioner or dental surgeon must be kept in the consulting physician’s medical record, except in the case of a consultation which occurs in a hospital, long-term care institution or multi-specialty clinic where common medical records are maintained. In such cases, the written request may be contained on the common medical record.

The request identifies the consultant by name and/or the specialty being consulted, the referring physician, nurse practitioner or dental surgeon by name and billing number, and identifies the patient by name and health number.

The written request sets out the information relevant to the referral and specifies the service(s) required.
