Version: 20180331

Release Date: April 3, 2018


The SNOMED CT Odontogram release is a reference set (refset) developed from 2015-2017 as a tool to exchange basic oral health status information between dental clinicians using a standardized format and to support gathering of research and quality data based on the most common visualizations for clinicians worldwide. The purpose of the refset is twofold: 1) it is designed to identify a set of core content that can realistically be exchanged for an odontogram and 2) a small set may allow Electronic Dental Record (EDR) vendors and the dental payer community to move quickly and inexpensively implement tools that will allow for their use. The odontogram refset contains primarily terms from four of the SNOMED CT hierarchies: The most common one is Procedures, but it also includes several Body Structures and some Findings and Disorders.

SNOMED CT Odontogram Refset Package

Release Date: October 2017

Version: July 2017

Release Notes: The SNOMED CT Odontogram release is a reference set (refset) developed from 2015-2017 as a tool to exchange basic oral health status information between dental clinicians using a standardized format and to support gathering of research and quality data based on the most common visualizations for clinicians worldwide. The purpose of the refset is twofold: 1)it is designed to identify a set of core content that can realistically be exchanged for an odontogram and 2)a small set may allow Electronic Dental Record (EDR) vendors and the dental payer community to move quickly and inexpensively implement tools that will allow for their use. The odontogram refset contains primarily terms from four of the SNOMED CT hierarchies: The most common one is Procedures, but it also includes several Body Structures and some Findings and Disorders.

ICNP to SNOMED CT Interventions Release

Release Date: March 2017

Version: January 2017

Release Notes: The International Classification of Nursing Practice (ICNP) to SNOMED CT International Release Nursing Interventions equivalency table is a product of an ongoing program of work carried out under a pre-existing collaboration agreement between the International Council of Nurses (ICN) and the SNOMED CT International (SI). The initial effort centered on nursing diagnoses, specifically problems. The focus of this release document is on the identification of SNOMED CT equivalencies for ICNP nursing interventions. The table of equivalence provides a vehicle for transforming ICNP-encoded data into SNOMED CT (e.g. an ICNP concept in a local system can be transformed via the table to the equivalent SNOMED CT concept for use in a multidisciplinary record). By providing a robust pathway from ICNP to SNOMED CT, the table of equivalence helps to ensure that users of ICNP can continue to use their preferred terminology while remaining a central part of the bigger picture and wider implementation of SNOMED CT globally.

Please Note: Users of the table should comply with licensing arrangements for both ICN and SNOMED International.
