OIDs are machine readable, globally unique object identifiers used in health care interoperability for various purposes including the identification of code systems and subsets used in exchange of health care information.
As the Canadian affiliate for HL7, Infoway can register OIDs on behalf of Canadian implementers free of charge. There is a $500 USD fee per OID request if done directly with HL7 International.
If you need to register an OID, you can benefit from the savings Infoway offers. Visit the OID page to access the registration form and submission guidelines.
