Standards Access

To access licensed international and national health information standards (e.g. SNOMED CT), simply login to your Infoway Account and reconfirm acceptance of the Terms of Use and License Agreements annually. Fees are only collected for access and use of HL7 International materials.

All SNOMED CT, LOINC and Infoway software tools are available at no cost to users with an active Infoway account. Information provided during Infoway Account registration may be used to respect our contractual commitments with licensors such as HL7 International and SNOMED International, or to request feedback on artifacts downloaded via Terminology Gateway or Terminology API. Email us to opt out from receiving feedback emails of terminology downloads from the maintaining organization.
