Register for an OHIP billing number

You must register with the Ministry of Health (the ministry) in order to receive an Ontario Health Insurance Plan (OHIP) billing number to submit claims for insured services.

In order to register for an OHIP billing number, the ministry requires that you hold a valid certificate with the College of Physicians and Surgeons of Ontario (CPSO) and you must have an Ontario practice address.

For further information on how to register for an OHIP billing number, please refer to the ministry’s webpage on OHIP Billing Number Registration.

Mandatory practice address reporting

All physicians are required under Regulation 57/97 to the Health Insurance Act to provide in writing to the ministry, an address for every place they regularly provide insured services in Ontario to insured persons. If a physician plans to change the place where they regularly provide insured services, they must give the ministry the address of the new place 30 days before the change occurs.

Where multiple addresses exist, the physician should identify which address is the primary practice site where possible. In addition to each address, physicians must indicate whether services are provided as a locum tenens and/or provided as delegated procedures carried out under direct supervision of the physician.

Provisions governing delegated procedures can be found in the General Preamble section of the Schedule of Benefits for Physician Services.

Practice addresses are not considered personal information and may be disclosed upon request pursuant to the Freedom of Information and Protection of Privacy Act and as such, it is recommended that your residential address not be provided.

The ministry may require supporting documentation to validate your address information and may request information on any other practice addresses. In addition, you may be contacted to verify and/or update your address data currently on file with the ministry.
